Introduction
Designers of constructions, manufacturers of construction products, users of constructions, owners of
constructions and others active in the building and construction sector are increasingly demanding
information that enables them to make decisions to address environmental impacts of buildings and
other construction works. These demands are currently being addressed only through various national
initiatives applying a variety of approaches.
It is essential that there be uniformity in the means of expressing environmental product declarations.
This includes having a consistent way of arriving at the declaration that is based on basic life-cycle
inventory data and additional information not based on life-cycle assessment (LCA). The user expects
non-biased information, which is expected be consistent with the best current practice and
understanding over the lifetime of the standard.
According to the set of four International Standards dealing with environmental labelling, (ISO 14020,
ISO 14021, ISO 14024 and ISO 14025), environmental labels and declarations are divided into three
principal types:
 General principles: ISO 14020;
 Self-declared environmental claims, type II environmental labelling (ISO 14021);
 Principles and procedures of environmental labels and declarations, types I and III environmental
labelling (ISO 14024 and ISO 14025).
This International Standard is one in a suite of International Standards dealing with sustainability in
building construction that includes the following:
a) ISO 15392 Sustainability in building construction — General principles;
b) ISO 21932 Buildings and constructed assets — Sustainability in building construction —
Terminology;
c) ISO/TS 21929-1 Sustainability in building construction — Sustainability indicators — Part 1:
Framework for development of indicators for buildings;
d) ISO 21930 Sustainability in building construction — Environmental declaration of building
products;
e) ISO/TS 21931-1 Sustainability in building construction — Framework for methods of assessment
for environmental performance of construction works — Part 1: Buildings.
Unlike the International Standards listed in a), b), c) and e), ISO 21930 (this International Standard)
deals only with environmental impacts and aspects and excludes consideration of the social and
economic aspects of sustainability. The relationship among the International Standards is elaborated in
Figure 1.

Sustainability in buildings and civil engineering works — Core
rules for environmental declaration of construction products and
services used in any type of construction works
1
Scope
This International Standard provides the principles and requirements for Type III environmental
declarations (EPD) for construction products and services used in any type of buildings and civil
engineering works. In this International Standard, unless otherwise designated, the term construction
product is used for any goods or service related to buildings and civil engineering works.
This International Standard contains specifications and requirements for the EPD of construction
products and services used in any types of construction works. Where this International Standard
contains more specific requirements, it complements ISO 14025 for the EPD of construction products
and services used in any type of construction works.
This International Standard contains core set of product category rules (PCR) for Type III
environmental declarations for any construction products.
This International Standard, as the core PCR document:
1.
includes the mandatory requirements (elements) that may not be altered in any PCR based on this
International Standard;
2.
describes which stages of a construction product's life cycle are considered in the EPD and which
processes are to be included in the life cycle stages, and how the stages are subdivided into
information modules;
3.
includes the rules for calculating the life cycle inventory (LCI), environmental indicators and the life
cycle impact assessment (LCIA) result reported in the EPD;
4.
defines rules for the development of scenarios;
5.
includes the rules setting indicators, etc., for relevant environmental and technical information that
is not covered by LCA;
6.
defines the core elements of EPD content;
7.
defines the generic template to present environmental information in a structured and consistent
way and in a common format;
8.
establishes the structure of a project report;
9.
defines the conditions under which construction products can be compared based on the
information provided by an EPD;
10. provides guidance on product category rules for sub-categories of construction products.
Environmental declarations for construction products, as described in this International Standard, are
primarily intended for use in business-to-business communication, but their use in business-toconsumer communication under certain conditions is not precluded.
This International Standard specifies certain methodological aspects for inclusion in business-toconsumer communication, but refers to ISO 14025:2010 for further requirements. Requirements for

ISO/CD 21930
Type III environmental declaration programmes that are verified by a third party and based on LCA are
found in ISO 14025 and are followed in this standard.
The safety of the working environment is not included in this International Standard.
The assessment of social and economic impacts at the product level is not covered by this International
Standard.

General aspects
4.1 Objectives of the core PCR (General)
An EPD provides quantified environmental information for a construction product or service on a
harmonized and scientific basis. The purpose of an EPD in the construction sector is to provide the basis
for assessing buildings and other construction works, and identifying those, which cause less stress to
the environment. The EPD may also provide additional information on aspects such as emissions to
indoor air and to local environment (air, soil and water). The PCR provides the set of rules,
requirements and guidelines that shall be applied to the development of an EPD
In addition to the requirements of this International Standard, the principles and procedures set out in
ISO 14025, ISO 21931-1 and ISO 15392 shall apply. This International Standard contains additional
specifications and requirements for the EPD of construction products. Where this International
Standard contains more specific requirements, it seeks to complement ISO 14025 for the EPD of
construction products. However, where the requirements of this standard conflict with the
requirements of ISO 14025 for the development of PCR for construction products the, requirements of
this standard shall apply. In addition, the principles of environmental declarations as described in ISO
14020 apply.
EPD of construction products are based on LCA and reported divided in common generic information
modules. Relevant environmental aspects that have not been covered by LCA are addressed as
additional environmental information; see 8.2.4.
Thus, the objective of this core PCR is to provide consistent rules to:
 provide verifiable and consistent data for an EPD, based on LCA and additional information;
 ensure EPD provide verifiable and consistent product related technical data and subjects for
scenarios for the assessment of the environmental performance of construction works;
 ensure EPD provide verifiable and consistent product data related to release of dangerous
substances to indoor air in the use stage, to air, soil and water during the life cycle and substances
of very high concern;
18
© ISO #### – All rights reserved
ISO/CD 21930
 explain how EPD can be used for comparison of construction products in the context of construction
works;
 enable the communication of the environmental information of products from business to business
by EPD;
 ensure the basis, subject to additional requirements, for the communication of the environmental
information of construction products to consumers;
 provide guidance on the development of specific rules for sub-categories of products within the
product category of construction products.
4.2 PCR hierarchy and EPD types
4.2.1 Core PCR structure
The core PCR includes all the rules for the development of EPD that can be equally applied to any
construction product i.e. on a horizontal level. In addition, general rules for developing sub-category
PCR are described.
Any sub-category PCR shall include the following list of those elements of the core PCR that may not be
changed in any way:
1. Methodological framework shall include:
 definition of system boundaries (e.g. allocation of processes to modules);
 additional technical information (as basis for scenario);
 criteria for cut off;
 selection of data;
 data quality requirements;
 units;
 requirements for comparability.
2. Inventory analysis shall include:
 collection of data;
 calculation rules for the inventory (i.e. allocation of flows to processes);
 data quality.
3. Impact assessment shall include:
 definition of characterisation factors.
4. Content of EPD shall include:
© ISO #### – All rights reserved
19
ISO/CD 21930
 declaration of general information;
 declaration of the methodological framework;
 declaration of environmental parameters derived from LCA:
 declaration LCA results from life cycle impact assessment;
 declaration LCA results from life cycle inventory.
 declaration of environmental information not derived from LCA;
 declaration of additional information.
5. Communication formats – ITM;
6. Project report.
4.2.2 Relation between Core PCR and sub-category PCR
The core PCR provides all horizontal requirements for any PCR for construction products. However, for
some subcategories among the overall product category of construction products, horizontal
requirements might have to be specified further. The main purpose of the sub-category PCRs is to
develop rules for scenarios for all information modules, except A1 to A3, see Figure 2.
For such product subcategories, this includes for instance:
 more precise product descriptions;
 definition of the type of EPD and any information modules to be assessed;
 detailed definition of technical information and/or scenarios to be provided for specific information
modules;
 provision of specific scenarios for information modules beyond the gate; i.e. for the construction
stage, use stage, end-of–life stage, for recycling or reuse scenarios;
 detailed descriptions of the end-of-waste state for the specific product subcategories;
 detailed description of which processes belong to which modules in the end of life stage;
 additional requirements for descriptions of the specific technical information that should be
provided for the product, transparency about constituents and/or descriptions of manufacturing
processes.
Such additional requirements or further specifications for sub-categories of construction products will
result in a sub-category PCR document that includes:
a) the same structure and text as in the core PCR and then the additional elements specifications valid
for the sub-category PCR, or alternative
b) just the headings from and referring to the core PCR and the text describing the additional elements
and specifications.

ISO/CD 21930
It is important to recognise that requirements and descriptions from the core PCR shall be followed by
for any sub-category PCR. These are the horizontal rules, which are needed to safeguard the principles
of the EPD development as well as consistency of data among the overall category of construction
products. Figure 2 illustrates which elements of the core PCR can include additional elements or
specifications to meet the needs of product sub-categories and which shall stay unaltered.

market acceptance; see ISO 14025.
4.3 Life cycle stages and their information modules
The LCA in the EPD is dived in four life cycle stages and a number of information models, see Figure 3.
These life cycle stages describe the entirely life cycle of any construction product. As a supplement, the
information stage D is added, and address loads and benefits beyond the discard products end of life.
Stage D deals with potential future use of the material when the construction product is recycled in
future and its environmental consequences.

ISO/CD 21930
The environmental information of an EPD shall be subdivided into the information module groups A1A3, A4-A5, B1-B5, B6-B7, C1-C4 and the different modules listed in section 5.2.4.6 valid for different
options for stage D. An EPD shall as a minimum comprise the product stage modules, A1-A3, to comply
with this International standard.
For products where operational energy and/or water use are significant or if other resources are
consumed during the operation of the product, module B6 and B7 are mandatory with respect to
technical information, see Table 10. As for products that their performance at use stage are important,
the assessment of use stage shall be mandatory.
Information modules within any of the life cycle stages are communicated depending on the types of
EPD as specified in 4.3.1.
The modular set up of the LCA underlying an EPD (see Figure 2) allows easy organisation and
expression of data packages throughout the life cycle of the product. This approach requires that the
product system boundaries for the life cycle stages and the information modules included are
transparent, well defined and applicable to any construction product.
The setting of the product system boundaries follows the two principles:
a) The “modularity principle”: Where processes influence the product’s environmental performance
during its life cycle, they shall be assigned to the module of the life cycle where they occur; all
environmental aspects and impacts are declared in the life cycle stage where they appear.
b) The “polluter pays principle”: Processes of waste processing shall be assigned to the product system
that generates the waste until the end-of-waste state is reached.
4.3.1 Types of EPD with respect to Life Cycle Stages covered
An EPD of a construction product (goods and services), as defined here, provides information modules
for the assessment of the environmental performance of buildings; see ISO21931-1, and civil
engineering works. The information modules can be used to combine the environmental impacts from
materials, products, components or services to an assessment on construction or civil engineering
works or a part of such works over its life cycle.
The LCA based information in an EPD may cover different combinations of modules i.e. cover different
life cycle stages or parts thereof. The following different types of EPD are defined and illustrated in
Figure 4:
Cradle to gate: Covers the mandatory production stage e that is divided into the information modules
extraction and upstream production (raw material supply), transport to factory and manufacturing. The
LCA result is reported based on a declared unit.
Cradle to gate with options: Covers the mandatory production stage and optional modules from the
construction, use and end-of-life stage. The LCA results are reported based on a declared unit unless the
use stage is completely included. In that case a functional unit may also be defined. Modules beyond the
gate are based on scenarios. Examples for cradle to gate with options are:
 Cradle to central warehouse: Covers the mandatory production stage and the distribution to a
central warehouse in the given country or region as well as the storage processes (A4). The LCA
result is reported based on a declared unit. The transportation to the central warehouse module is
based on scenarios.
23
ISO/CD 21930
 Cradle to site: Covers the mandatory production stage and transportation to construction site. The
LCA result is reported based on a declared unit. The transportation to site module is based on
scenarios.
 Cradle through construction: Covers the mandatory production stage and both transport to site
and construction installation on site. The LCA result is reported based on a declared unit. Modules
beyond the factory gate are based on scenarios.
 Cradle to gate and maintenance Covers the mandatory production stage and maintenance
processes of the product during its service life (B2).
 Cradle to gate and end of life: Covers the mandatory production stage and the relevant end of life
modules of demolition or extraction from the building (C1), transportation from the building site to
the site for the end of life processes (C2), any waste management processes up to the end of waste
status e.g. scrap collection (C3) and/or final deposition of wastes e.g. deposition of waste on landfill
site (C4).
Cradle to grave: Covers the mandatory production stage and any of the information modules from the
construction, use and end-of-life stage. The LCA results are reported based on a functional unit. Modules
beyond the gate are based on scenarios.
Stage D includes supplementary information on environmental burdens and benefits when some or the
entire product is recovered, recycled or reused for a new product system. Stage D is voluntary
information and may be reported in any EPD for any of the different EPD types given above.

For the development of sub-category PCR, the programme operator shall be responsible to define any
default types of EPD describing the information modules where technical information or scenarios shall
be provided.
NOTE 1
Information modules can supply information for processes for which there is no EPD available, e.g. a
cleaning process.
NOTE 2
An information module may contain: the values of the pre-determined parameters and the technical
information underlying their quantification, relevant technical information for further calculation of the
environmental performance, scenarios for further calculation of the environmental performance.
NOTE 3
It is possible to have an EPD for a substance or preparation (e.g. cement), for a product (e.g. window),
for a construction service (e.g. cleaning service as part of maintenance) and for a construction (an assemblage of
products) and/or a building element (e.g. wall) or for technical equipment (e.g. lift).
25
ISO/CD 21930
4.3.2 Average EPD for groups of products
EPD may be developed for similar products from the same manufacturing plant and company using
data specific to that product. EPD may also be developed for groups of products using averaged
environmental performance data. Such average EPD may in practice significantly reduce the effort
associated with producing separate EPDs for similar products, or gives an EPD that is representative
market.
Similar products included in the average EPD should not differ in their environmental impacts by more
than +/-10% from the reported average value for each impact category. In the case where this rule is
not met, it is still possible to include these products in the same EPD e.g. as separate elements in a table.
In case where a typical representative value is chosen for each impact category for a product group
(resulting in a reference average), the value reported shall be the worst-case performance within the
range of variation.
For all types of average EPD, the declaration shall include a description of what the EPD represents. The
description shall at least include;
 a technical description of the average product group(such as density or a property like U-value);
 a description of number of manufacturing plants included in the EPD, and
 a description of number of manufacturing companies included. If the EPD includes data from more
than one company it becomes a sector representative EPD and a description of the market
representation shall therefore be stated (e.g. the EPD represent more than 75% of the products sold
on the North American market).
4.4 Development and use of PCR and PCR for a product sub-category
4.4.1 Development of PCR
Any stakeholder may develop a PCR, but the process shall be managed by a programme operator and
include an open, participatory consultation with interested parties. Thus, any organization that wishes
to create a PCR needs to identify a programme operator first.
4.4.2
Development of PCR for a product sub-category
4.4.2.1 Development of PCR for a product sub-category, general aspects
The requirements of 4.2 apply. The PCR review shall be conducted per ISO 14025. For a PCR for a
product subcategory to conform to this International Standard, the review shall not alter the core rules.
4.4.2.2 Determine the product subcategory to which the PCR will be applicable
The PCR shall clearly define the product subcategory for which the rules apply. It is important to define
precisely the product sub-category.
ISO 14025 states that a product category is a group of products that perform the same function. Product
sub-categories shall be primarily defined by product functionality. This includes a product description,
functions, and the use of the products in the category.
This description should also state which products are not covered by the PCR if there is potential
ambiguity in the product subcategory.
26
© ISO #### – All rights reserved
ISO/CD 21930
4.4.2.3 Perform a thorough search for product specific PCRs that belong to the same subcategory.
Programme operators can facilitate harmonisation when developing PCR for a product category by
considering readily available PCR documents in the same product category and in the appropriate
market area. Justification for not using readily available PCR shall be based on the content of existing
PCR documents with respect to this Core PCR and not, for example, on the origin of any particular PCR.
The efforts undertaken, the outcome and if relevant the explanations for not using readily available PCR
shall be reported in the sub-category PCR document.
4.4.3 Use of PCR and PCR for a product sub-category
All PCRs for construction products shall meet the requirements in the core rules according to this
standard. They are intended to ensure consistent assessment at the building level and comparability
where the requirements of ISO 14025:2006 clause 6.7.2 are met.
Four approaches can be taken to develop a sub-category PCR they are as follows:
a)
Single PCR without sub-category PCR:
When referencing these Core Rules in a PCR it shall be stated in the EPD that the requirements of this
standard are followed.
b)
Single PCR, product specific guidelines:
An EPD programme may cover all construction products with a single PCR and optional subcategory
PCR. In this case the EPD shall use these core rules as the basis of any PCR for sub-categories, but
additional information must be provided Sub-category PCR can be PCR for a smaller product category
which is part of the larger product category PCR for construction products. For example:
 the requirements for provision of additional environmental information, including any
methodological requirements (e.g. specifications for the assessment of eco-toxicological aspects);
 detailed description of the materials and substances to be declared (e.g. information about product
content, including specification of materials and substances that can adversely affect human health
and/or the environment, in all stages of the life cycle).
c)
Overarching guidelines and sub-category PCR:
An EPD programme can reference these core rules and provide product-specific PCR that each act as a
PCR to ISO 14025. The product-specific PCR can provide more detail of the application of the rules for
the specific product, for example the specific application of the general system boundaries for that
product, the technical information to be provided for the product.
d)
Product Specific PCR:
An EPD programme can use these core rules as the basis of PCR, which only cover one or more subcategories of construction products.
4.5 Use of EPD for construction products
The environmental information on construction products is intended mainly for business-to-business
communication and its prime purpose is to provide measurable and verifiable input for the assessment
27
ISO/CD 21930
of the environmental performance of buildings and civil engineering works. However, some EPD may be
used in the business-to-consumer marketplace and the user of this International Standard shall follow
the provisions of ISO 14025:2006, Clause 9.
The users of this International Standard are both the information providers and information users,
including those setting up Type III environmental declaration programmes.
The manufacturer, or group of manufacturers, of the building product is the sole owner of the data and
takes liability and responsibility for the EPD of the building product, according to the PCR. Apart from
these manufacturers, no one is authorized to declare the environmental performance of the building
product.
4.6 Comparability of EPD for construction products
Comparison of construction products using an EPD is preferable to be carried out in the context of
different construction works and different intended use applications. Consequently, comparison of the
environmental performance of construction products using the EPD information shall be based on the
product’s intended use in and its impacts on the environment as part of a building over the full life
cycle, and shall consider all relevant information modules. Such a comparison requires scenarios in the
building context.
Comparisons are possible at the sub-building level, e.g. for assembled systems, components, services, or
products for one or more life cycle stages. In such cases, the principle that the basis for comparison of
the assessment is the entire building, shall be maintained by ensuring that the same functional
requirements are met,
 such comparison has to be based on a functional unit
 the environmental performance and technical performance of any construction (assembled
systems, components, or products) excluded are the same, and
 the amounts of any material excluded are the same, and
 excluded processes or life cycle stages are the same, and
 the influence of the product systems on the operational aspects and impacts of the building are
taken into account or are the same.
NOTE 1
EPD that are cradle to gate are tool to compare construction products and construction services only if
the scenarios are identical.
The information provided for such comparison shall be transparent to allow the purchaser or user to
understand the limitations of comparability.
NOTE 2
The difference between two products may be insignificant in the building context.
4.7 Documentation and communication
The result form an EPD project shall be reported on three different levels as given in Figure 5; a project
report, an Information Transfer Matrix and an EPD.

The project report is the systematic and comprehensive summary of the project documentation
supporting the verification of an EPD. The project report shall record that the LCA based information
and the additional information as declared in the EPD meet the requirements of this International
Standard. The project report should contain any data and information of importance for the data
published in the EPD and as required in this European Standard. Special care is necessary to
demonstrate in a transparent way in which the data and information declared in the EPD results from
the LCA study and how the reference RSL has been established.
The project report shall be made available to the verifier with the requirements on confidentiality
stated in EN ISO 14025:2006.
The project report is not part of the public communication.
The requirement for the project report is given in clause 9.
An Information Transfer Matrix (ITM) a generic template to present environmental information in a
structured and consistent way and in a common format.
It is relevant to the use of the EPD in the construction work chain where materials and products are
assembled into new products and assemblies, each with their own EPD.
This International Standard will improve handling of the data from EPD at the construction works level
and the assessment of environmental performance of construction works.
The communication format is presented in clause 8.
In clause 7 the content of an EPD in accordance with this International standard is presented.

Product Category Rules for LCA
5.1 Product category
At the highest level, all products used in buildings and other types of construction works belong to the
overall product category of construction products. More specific sub-categories may be defined for
29
ISO/CD 21930
certain groups of construction products to address additional environmental information not based on
LCA and provide more specific rules for implementation of these core rules.
The product category referred to in this standard includes all construction products and construction
services for buildings and other construction works.
5.2 Methodological framework
5.2.1 Declared unit
The declared unit is used instead of the functional unit when the precise function of the product or
scenarios at the building or construction work level is not stated or is unknown. The declared unit
provides a reference by means of which the material flows of the information module of a building
material or component are normalised mathematically.
The declared unit provides the reference for combining the material flows attributed to the product and
the relevant environmental impacts, taking into account the selected stages of the product’s incomplete
life cycle; see Figure 2. It shall relate to the typical applications of products and their product categories.
The declared unit in the EPD shall be one of the following:
 an item, an assemblage of items, e.g. 1 brick, 1 window (dimensions to be specified);
 mass (kg), e.g. 1 kg of cement;
 length (m), e.g. 1 metre of pipe, 1 metre of a beam (dimensions shall be specified);
 area (m2), e.g. 1 square metre of wall elements, 1 square metre of roof elements (dimensions shall
be specified);
 volume (m3), e.g. 1 cubic metre of timber, 1 cubic metre of ready-mixed concrete.
A different unit may be declared for reasons that shall be explained and in such cases information shall
be provided on how to convert this unit to one or more of the required unit types.
EXAMPLE 1
If an EPD for an insulation material is declared in units of thermal resistance R D (m2K/W) in the
building, then a conversion factor, e.g. to 1 kilogramme of material is required.
For the development of, for example, transport and disposal scenarios conversion factors to mass per
declared unit shall be provided.
NOTE 1
Reasons for declaring units other than those listed include the need to use units normally used for
design, planning, procurement and sale.
The following information is the minimum that shall be provided together with the declared unit for the
building material or component:
 intended application;
 life-cycle stages that are included (information modules);
 reference service life of the product (only required for “use” and “maintenance” information
module);
30
© ISO #### – All rights reserved
ISO/CD 21930
 statement regarding the limitations of comparability.
If a product’s performance in any of the omitted life-cycle stages is relevant for its overall
environmental performance, the omission of this information shall be declared and justified. This
approach is also shown in Figure 3.
Information provided using a declared unit shall not be used for comparison unless their scenarios are
identical.
5.2.2 Functional unit
The functional unit defines the way in which the identified functions or performance characteristics of
the product are quantified. The primary purpose of the functional unit is to provide a reference by
which material flows (input and output data) of construction product’s LCA results and any other
information are normalised to produce data expressed on a common basis.
NOTE 1
Comparisons of construction products with the same functional unit follow the rules in 4.6.
The functional unit, used as the denominator provides the basis for the addition of material flows and
environmental impacts for any of the life cycle stages and their modules for the construction product or
construction service.
The functional unit of a construction product is based on:
 the quantified, relevant functional use or performance characteristics of the construction product
when integrated into a building, taking into account the functional equivalent of the building;
 the product’s reference service life (see 5.2.3) or required service life of the building or construction
work under defined in-use or use conditions.
Thus, quantification of both the qualitative and quantitative aspects of the function in relation to end
use in a building context e.g. ‘what’, ‘how much’, ‘how well’ and ‘for how long’ has to be performed.
NOTE 2
Guidance on the development of a functional unit is given in ISO 14040:2006, 4.2.2.
NOTE 3
Guidance on describing in-use conditions is given in Product Standards and ISO 15686-1,-2, -7, -8.
5.2.3 Reference service life requirement
RSL information to be declared in an EPD covering the use stage shall be provided by the manufacturer.
The RSL shall refer to the declared technical and functional performance of the product within a
building. It shall be established in accordance with any specific rules given in product standards and
shall take into account ISO 15686-1, -2, -7 and -8. Where product standards provide guidance on
deriving the RSL, such guidance shall have priority.
Information on the product’s RSL requires specification of compatible scenarios for the product stage,
construction process stage and use stage. RSL is dependent on the properties of the product and
reference in-use conditions. These conditions shall be declared together with a RSL and it shall be
stated that the RSL applies for the reference conditions only.
The RSL shall be verifiable.
31
ISO/CD 21930
The description of the reference service life (see also Annex A) may be based on data collected as
average data or at the beginning or end of the service life. The reference conditions for achieving the
declared technical and functional performance and the declared reference service life shall include the
reference service life data as described in Table 1, where relevant:

Units as appropriate
Requirements and guidance on the estimation of service life are given in normative Annex A.
5.2.4
System boundaries and technical information (for scenarios)
5.2.4.1 System boundaries and technical information (for scenarios), general
The LCA is divided in a number of information modules.
Scenarios and technical information are necessary for the application of EPD in building assessment.
Therefore, EPD should when relevant, include information about reference service life of the product, as
given in Table 2, modules transportation, construction, use, operation, maintenance and replacements
based on the reference service life.
When an information module in the LCA is included it shall follow the scope as defined in this clause.
5.2.4.2 A1-A3 Product stage
A1-A3 is required to be included in the EPD independent of type of EPD as stated in clause 5.3.1. The
system boundary with nature is set to include those processes that provide the material and energy
32

ISO/CD 21930
inputs into the system and the following manufacturing, and transport processes up to the factory gate
as well as the processing of any waste arising from those processes.
The product stage includes the following three information modules (processing up to the end-of-waste
state or disposal of final residues including any packaging not leaving the factory gate with the
product):
A1, raw material extraction and processing, processing of secondary material input (e.g. recycling
processes):
 A1 Extraction and processing of raw materials (e.g. mining processes) and biomass production and
processing (e.g. agricultural or forestry operations);
 A1 Reuse of products or materials from a previous product system;
 A1 Processing of secondary materials used as input for manufacturing the product, but not
including those processes that are part of the waste processing in the previous product system;
 A1 Generation of electricity, steam and heat from primary energy resources used for extraction and
processing of raw materials, also including their extraction, refining and transport;
 A1 Energy recovery and other recovery processes from secondary fuels, but not including those
processes that are part of waste processing in the previous product system;
 A1 Waste processing of the waste from raw material packaging and raw material wastage including
transport, up to the end-of-waste state or disposal of final residues (see 5.2.4.5).
A2, transport of raw materials up to the factory gate and internal transport as given in Table 2;
A3, manufacturing:
 A3 Production of ancillary materials or pre-products;
 A3 Generation of electricity, steam and heat from primary energy resources used in manufacturing,
also including their extraction, refining and transport
 A3 Manufacturing of products and co-products;

In the case of input of secondary materials or energy recovered from secondary fuels, the system
boundary between the system under study and the previous system (providing the secondary materials
and secondary fuels) is set where outputs of the previous system, e.g. materials, products, building
elements or energy, reach the end-of-waste state (see 5.2.4.5).
Flows leaving the system at the end-of-waste boundary of the product stage (A1-A3) shall be allocated
as co-products (see 5.3.3.2). Loads and benefits from allocated co-products shall not be declared in
stage D (see 5.3.3.3). If such a co-product allocation is not possible, other methods may be chosen and
shall be justified. Therefore, as a general rule, potential loads or benefits from A1-A3 do not appear in
stage D.
NOTE 1
The output of waste during this life cycle stage may reach the end-of-waste state when it complies with
the conditions described in 5.2.4.5, end-of-life stage. They are then allocated as co-products as 5.4.3.2.
5.2.4.3 A4-A5, Construction process stage, information modules
The construction process stage includes the following two information modules:
 A4, Distribution, and
 A5, installation into any type of construction or civil engineering works.

These information modules include provision of all materials, products and energy, as well as waste
processing up to the end-of-waste state or disposal of final residues during the construction process
stage. They also include all impacts and aspects related to any losses during this construction process
stage (i.e. production, transport, and waste processing and disposal of the lost products and materials).
A4, Distribution:
 A4 Storage of products, including the provision of heating, cooling, humidity control, etc. if relevant;
 A4 Transportation from the production gate to the central warehouse or storage site if relevant;

5.2.4.4 Use stage
The use stage includes the information modules covering the period from the handover of the building
or construction works to when it is deconstructed or demolished. The duration of the use stage of
products may be different from the required service life of a construction.
The use stage includes the use of construction products, equipment and services in their proper
function. It also includes their use for protecting, conserving, moderating or controlling a construction,
e.g. modules describing the building operation through building related services such as heating,
cooling, lighting, water supply and internal transport (provided e.g. by lifts and escalators). It also
includes maintenance (including cleaning), repair, replacement and refurbishment.
It is recognised that it may be difficult to separate all use stage processes and the connected aspects and
impacts into these separate modules. However, any deviation from the categorisation of aspects and
impacts into Modules B1-B5 and B6-B7 shall be transparently reported and justified.
37
ISO/CD 21930
Flows leaving the system at the end-of-waste boundary of the product stage (B1-B7) shall be allocated
as co-products (see 5.3.3.2). Loads and benefits from allocated co-products shall not be declared in
stage D (see 5.3.3.2). If such a co-product allocation is not possible, other methods may be chosen and
shall be justified. Therefore, as a general rule, potential loads or benefits from B1-B7 do not appear in
stage D.
B1-B5, Use stage, information modules related to the building fabric or construction work
The use stage includes the following five information modules:
 B1, use or application of the installed product;
 B2, maintenance;
 B3, repair;
 B4, replacement;
 B5, refurbishment;
including provision and transport of all materials, products and related energy and water use, as well as
waste processing up to the end-of-waste state or disposal of final residues during this part of the use
stage. These information modules also include all impacts and aspects related to the losses during this
part of the use stage (i.e. production, transport, and waste processing and disposal of the lost products
and materials).
B1 Use of the installed product in terms of any emissions to the environment (not covered by B2-B7)
The module “use of the installed product” covers environmental aspects and impacts connected to the
normal (i.e. anticipated) use of products, not including those related to energy and water use, which are
dealt with in B6 and B7) e.g. release of substances from the facade, roof, floor covering, walls and
different surfaces (interior or exterior) are reported as additional information (see 6.1).
B2 Maintenance
The module “Maintenance” covers the combination of all planned technical and associated
administrative actions during the service life to maintain the product installed in construction, in a
construction works or its parts in a state in which it can perform its required functional and technical
performance, as well as preserve the aesthetic qualities of the product.
This will include:
 B2 Preventative and regular maintenance activity such as cleaning, and the planned servicing,
replacement or mending of worn, damaged or degraded parts

B4 Replacement
The module “replacement” covers the combination of all technical and associated administrative actions
during the service life associated with the return of a construction product to a condition in which it can
perform its required functional or technical performance, by replacement of a whole construction
element.
Replacement of a broken component or part due to damage should be included as “repair”, but
replacement of a whole construction element due to damage should be considered as “replacement”.
Replacement of a whole construction element as part of a concerted replacement programme for the
building should be considered as “refurbishment”.
This will include:
 B4 The production (A1-A3) of any component and ancillary products used for replacement,
 B4 The transportation (A4) of any component and ancillary products used for replacement
 B4 Use of related energy and water; including production and distribution
 B4 Transportation of any waste from replacement processes or from replacement related
transportation;
 B4 The end-of-life processes of any waste from transportation and the replacement process,
including any part of the component and ancillary materials removed.

B6-B7, use stage, information modules related to the operation of the building
45
ISO/CD 21930
These information modules include provision and transport of all materials, products, as well as energy
and water provisions, waste processing up to the end-of-waste state or disposal of final residues during
this part of the use stage.
The use stage related to the operation of the building and constriction works includes the following two
information modules:
 B6, operational energy use (e.g. operation of heating system and other building related installed
services);
 B7, operational water use.
B6 Energy and water use to operate building integrated technical systems
Building integrated technical systems are installed technical equipment supporting operation of a
building or construction works. This includes technical building systems for heating, cooling,
ventilation, lighting, domestic hot water and other systems for sanitation, security, fire safety, internal
transport and building automation and control and IT communications.
The boundary of the module “Energy use to operate building integrated technical systems’’ shall
include:
 B6 Generation, distribution and use of energy during the operation of the product (the building
integrated technical system), together with its associated environmental aspects and impacts
including processing and transportation of any waste arising on site from the use of energy.
If relevant for the product group, aspects related to the production, transportation and installation of
building integrated technical systems equipment shall be assigned to Modules A1-A5; e.g. radiators,
boiler, ventilation system. Energy use during maintenance, repair, replacement or refurbishment
activities for the equipment shall be assigned to Modules B2-B5. Aspects related to the waste processing
and final disposal of equipment shall be assigned to Modules C1-C4.
The module "Operational water use by building integrated technical systems" covers the period from
the handover of the building or construction works to when the building is deconstructed or
demolished.
The boundary of the module ‘operational water use by building integrated technical systems’ shall
include:
 B7 Water use during the operation of the product (the building integrated technical system),
together with its associated environmental aspects and impacts considering the life cycle of water
including production and transportation and waste water treatment.
If additional technical information is provided in the EPD for building integrated technical systems for
using energy or water related to operation of the building, the information in Table 9 shall be provided
to specify the energy and water use scenarios or to support development of the energy and water use
scenarios at the level of the building assessment.

5.2.4.5 C1-C4 End-of-life stage
The end-of-life stage includes the following information modules:
 C1, de-construction, demolition;
 C2, transport to waste processing;
 C3, waste processing for reuse, recovery and/or recycling;
 C4, disposal.
including provision and all transport, provision of all materials, products and related energy and water
use.
The end-of-life stage of the construction product starts when it is replaced, dismantled or deconstructed
from the building or construction works and does not provide any further functionality. It can also start
at the end-of-life of the building, depending on choice of the product’s end-of-life scenario.
During the end-of-life stage of the product or the building, all output from dismantling, deconstruction
or demolition of the building, from maintenance, repair, replacement or refurbishing processes, all
debris, all construction products, materials or construction elements, etc. leaving the building, are at
first considered to be waste. This output however reaches the end-of-waste state when it complies with
all the following criteria:
 the recovered material, product or construction element is commonly used for specific purposes;
47
ISO/CD 21930
 a market or demand, identified e.g. by a positive economic value, exists for such a recovered
material, product or construction element;
 the recovered material, product or construction element fulfils the technical requirements for the
specific purposes and meets the existing legislation and standards applicable to products;
 the use of the recovered material, product or construction element will not lead to overall adverse
environmental or human health impacts.
NOTE 1
The "specific purpose" in this context is not restricted to the function of a certain product but can also
be applied to a material serving as input to the production process of another product or of energy.
The criterion for "overall adverse environmental or human health impacts" shall refer to the limit
values for pollutants set by regulations in place at the time of assessment and where necessary shall
take into account adverse environmental effects. The presence of any hazardous substances exceeding
these limits in the waste or showing one or more properties as listed in existing applicable legislation,
e.g. in the European Waste Framework Directive, prevents the waste from reaching the end-of-waste
state.
The end-of-life system boundary of the construction product system to stage D is set where outputs, i.e.
secondary materials or fuels, have reached the “end-of-waste” state.
The end-of-life stage includes modules:
 C1 deconstruction, including dismantling or demolition, of the product from the building and energy
use for this work, including initial on-site sorting of the materials;
 C2 transportation of the discarded construction product as part of the waste processing, e.g. to a
recycling site and transportation of waste e.g. to final disposal;
 C3 waste processing e.g. collection of waste fractions from the deconstruction and waste processing
of material flows intended for reuse, recycling and energy recovery. Waste processing shall be
modelled and the elementary flows shall be included in the inventory. Materials for energy recovery
are identified based on the efficiency of energy recovery with a rate higher than 60 % without
prejudice to existing legislation. Materials from which energy is recovered with an efficiency rate
below 60% are not considered materials for energy recovery.
NOTE 2
Only when materials have reached the end-of-waste-state can they be considered as materials for
energy recovery, provided the energy recovery process has an energy efficiency rate higher than 60%.
 C4 waste disposal including physical pre-treatment and management of the disposal site.
NOTE 3
In principle waste processing is part of the product system under study. In the case of materials leaving
the system as secondary materials or fuels, such processes as collection and transport before the end-of-waste
state are, as a rule, part of the waste processing of the system under study. However, after having reached the
“end-of-waste” state further processing may also be necessary in order to replace primary material or fuel input in
another product system. Such processes are considered to be beyond the system boundary and are assigned to
stage D.
Loads, (e.g. emissions) from waste disposal in module C4 are considered part of the product system
under study, according to the “polluter pays principle”.
The following information shall be provided for all construction products to specify the end-of-life
scenarios used or to support development of the end-of-life scenarios at the building level. Scenarios

5.2.4.6 Future reuse, material recycling and energy recovery
Stage D includes LCA based information that describes environmental benefits and loads if the analysed
product is reused, material recycled or energy recovered.
The result from stage D shall not – if not else is said in this standard – be compared to the result from
stage A to C and shall therefore be reported separately. The environmental performance reported in
stage D shall be used to give information on different handling options of the recovered material. The
environmental performance reported in stage D goes beyond the initial discard products lifecycle
(reported in stage A to C). Stage D gives information to support a resource efficient use of natural
resources and reduced environmental impact when handling the scraped product.
The inventory flows reported in Table 10, module C3, constitute the source information used as input
for the LCA calculations in life cycle stage D.
Different LCA approaches may be used in life cycle stage D. On a generic level different LCA approaches
may be divided in two system perspectives namely: attributional LCA and consequential LCA. Modules
in A to C follows an attributional approach, which is a system perspective where all products is assign to
the direct environmental burden that is allocated to the product from the different involved processes
in the products life cycle. In theory, following the attributional approach all products environmental
impact may be added up and corresponds then to the resulting global impact (sometimes referred to as
the 100% rule). A consequential LCA, on the other hand, also includes indirect environmental effects as
consequence of a change, which is typically handled with a process system expansion. A consequential
LCA expand the product cradle to-grave investigated and describes ‘what happens if’ in related product
systems, why the 100% rule is not valid in this system perspective. A challenge with consequential LCA
is to define these changes and its effect on the expanded product system. Both system perspectives are
applicable in stage D according to this standard. Stage D may therefore include a mix of these
approaches or just one system perspective.
49
ISO/CD 21930
As reported in Table 10, stage C3, different handling options of the discard product may be valid for the
very same product. These different alternatives and its consequences may be reported in Stage D on
voluntary basis. Stage D is designed to follow the same requirements concerning transparent and
modularity as applied the initial lifetime of the product (stage A to C).
Stage D includes the following options;
Attributional LCA;
 Reuse (RU) of the same product
 Material cascade recycling (CR)
Consequential LCA;
 Future material recycling (MR)
 Future energy recovery (ER).
If any of these options is accounted for, the following information applied shall be reported to specify
the scenarios and divided in a modular way as described in Table 11 to Table 14. Reuse is an applicable
method for recycling of the same product in a new context where the physical shape of the product is
essentially the same, but its intended use might differ from the original use (external doors might be
used as a table or as inside doors etc). Open loop recycling might be handled with material recycling or
cascade recycling and the latter alternative is also applicable for close loop recycling. Energy recovery is
in stage D handled with system expansion.
D-RU, Ruse
Reuse is in this standard handled as additional information compared to the initial use of the
construction product and reported separately in different modules in stage D. Reuse means that the,
more or less same physical product, is used at least once more. Due to the long lifetimes valid for most
construction products, a scenario setting where the initial product is used once more has to be based on
assumptions. The Reuse option shall account for a full life cycle, where these downs stream relevant
parts of the forthcoming life cycle follows the same scope as already defined in the modules in stage A
to C. The historical environmental impact related with the processing of the initial product will be
allocated to the initial product, which means that a secondary use will only account for the
environmental impact appearing after the initial products end of life (stage C). The information to be
reporting for reuse includes the following information modules:
 D-RU1 Upgrading, treatment; includes all processing performed that is made before the product is
put on the market again. This module continues where stage C ends. This module also includes
distribution and installation of the product with the same scope as described in stage A4 and A5.
The transport includes the average transportation of the product until it reaches the average new
construction site.
 D-RU2 Reuse route alternative A accounts for the same life cycle stages from module B and C that
are valid from the initial usage stage
 D-RU3 Reuse route alternative B. If optional reuse routs appears for instance on different markets
or for different intended use in any construction works, additional scenarios may be included
named A, B and so on.
 Total impact D-RU-route A. The summed environmental impact covering the entirely reused
products life cycle according to scenario A etc. may be reported.
50
© ISO #### – All rights reserved
ISO/CD 21930
The environmental ‘Total impact D-RU-route A’ may be compared with the summed environmental
impact for the initial product if they fulfil the same functional performance.
In practice, a physical reuse of a product might be combined with additional LCA based information in
stage D.
NOTE 1
Reuse shall not be mixed up with close loop recycling where the material is processed to a likewise
product (like melting the steel reinforcement to new reinforcement) or a complete new product in the case of
open loop recycling. Such handling alternatives may be in an LCA be treated either as ‘Material cascade recycling’
or the ‘Material recycling* alternative (as listed above). The latter alternative includes system expansion and the
first alternative accounts for a number of recycling loops where the environmental impact is shared typically even
across all products in the overall recycling cascade scenario described.

Specification; reuse of the same product
D-RU1 Upgrading, treatment

D-CR, Cascade recycling
Material from a scraped product that is processed and used in one or more future products, i.e. open
loop recycling, constitute a common chain of product system using the same basic material. According
to an attributional LCA it is possible to account for the full cascade chain and where common parts, like
raw material extraction, may be dived to all products. This environmental impact shall according to this
standard be dived evenly between all products in the cascade chain. This cascade recycling has to be
scenario based and therefore includes uncertainties. It is recommended to include more than one such
scenario in stage D.
Compared to the LCA methodology applied in module A to C the environmental impact is in that case
allocated temporally (and spatial) correctly. In the case of cascade recycling the environmental impact
will be (re-)allocated to other products in the defined cascade inapproachable when they didn’t
appeared temporally. This kind of LCA result does not follow a physical correct allocation approach, but
do instead reflect the environmental burden in a value chain where all product share common
processed equal. This kind of LCA result from stage D therefore gives an alternative view of the
environmental impact reported in stage A to C, and is comparable in that sense that they follow the
same system perspective. This means that the numerical figures reported in stage A to C is comparable
with the figures reported in stage D, but following two different allocation approaches. The information
given in stage D is therefore complementary for the same product analysed in the EPD.
The cascade recycling stage option accounts for a full life cycle and therefore includes the following
modules:
51
ISO/CD 21930
 D-CR1 upgrading, treatment; includes all processing performed that is made before the product is
put on the market again. This module continues where stage C ends. This module also includes
distribution and installation of the product with the same scope as described in stage A4 and A5.
The transport includes the average transportation of the product until it reaches the average new
construction site.
 D-CR2 Reuse route alt. A accounts for the same life cycle stages from module B and C that are valid
from the initial usage stage
 D-CR3 Reuse route alt. B. If optional reuse routs appears for instance on different markets or for
different intended use in any construction works, additional scenarios may be included named A, B
and so on.
 Average impact from route A. The average environmental impact from A to C and CR1 to CR3
covering relevant modules and where common processes are allocated evenly in the recycling
cascade according to scenario A etc.

D-MR, Material recycling
The Material recycling stage option accounts for all necessary life cycle stages and processes so it – as a
minimum – can replace an alternative material used on the market. This (traditionally limited) life cycle
scope might be expanded if other aspects that appear downstream shall be part of the LCA and wants to
be reported in the EPD. This LCA calculation option, therefore, does not at a mandatory state include a
full life cycle, but cradle to gate inventory. The ‘cradle’ in this case starts where the inventory from stage
C ends and the ‘gate’ represents at least the manufacturing site, where the material from the initial
product ends up after have been processed so it can replace another raw material. Note that this is
aiming at a raw material and have therefore not to be a finished product. Different materials are
handles as raw material in different forms on the trading market and also several forms as raw material
might be relevant. The specific material form of recycled material shall be described in the EPD. And if a
downstream life cycle after the raw material stage is accounted for in the LCA shall these stages be
reported in the EPD and documented according to Table 13.
The Material recycling alternative includes an assessment where the recycled (secondary) material
displaces the use of an alternative (marginal) material. This is in LCA referred to as system expansion
and the LCA results depend on which marginal material that is assumed to be displaced. To give the
user of the EPD an understanding of the consequences on different recycling options and the relative
difference between these, it is mandatory to report at least three scenario options. These options are;
52
© ISO #### – All rights reserved
ISO/CD 21930
 current practice;
 worst case;
 best case.
The current practice describes the replaced material on the representative market for the EPD. The
current practice is normally based on verifiable information. If such current practice cannot be
established a conservative approach shall be used. In this case, it shall be stated in the EPD that current
practice could not be defined and a description on the assumptions made shall be given briefly. Details
shall be reported in the LCA report and ICT/BIM communication format as defined in Table 13. Besides
current practice, a realistic worst case and best case shall be reported. The user of the EPD will then
understand the potential savings between reported alternatives. This scenario matter could also be
handled within a sub-oriented PCR and submitted for open consultation to branches outside the own.
The Material recycling option for stage D includes the following modules:
 D-MR1 Upgrading, treatment; includes all processing performed that is made before the upgraded
product is put on the market again where it replace a primary alternative material. This module
continues where stage C ends and might include additional transportation and several
manufacturing sites and processes;
 D-MR2 Displacement – current practice describes the environmental impact related to the displaced
material following the same life cycle scope as used in D-MR1;
 D-MR3 Displacement – best case current practice describes the environmental impact related to the
displaced material following the same life cycle scope as used in D-MR1;
 D-MR4 Displacement – worst case current practice describes the environmental impact related to
the displaced material following the same life cycle scope as used in D-MR1;
 D-MR Net impact – current practice. The net summed environmental impact from MR1 minus MR2,
covering the defined products life cycle according to the current practice scenario.
If this option for material recycling is chosen module D-MR1 to D-MR4 are mandatory and D-MR5 is
voluntary. It is also voluntary to give complementing scenarios, to the current practice scenario listed
above, in the EPD.
LCA methods used for this life cycle stage shall be reported separately in public available literature and
referred to in the EPD. Different methods might be used why comparison between different EPD might
not be applicable and shall be stated in the EPD. If a method is used established in a Sub-oriented PCR it
shall be added in the EPD that comparison between individual EPD concerning stage D-MR is possible
for the EPD following the same PCR or harmonised PCRs.

D-ER, Energy recovery
The energy recovery option accounts for all necessary life cycle stages and processes so the discard
product, or parts of it, can replace an alternative energy carrier used as fuel on the market. This option
follows the same approach as described above for material recycling including a cradle to gate
inventory scope. In this case, the 60% energy efficiency for the combustion process has to be fulfilled to
include the benefits with energy recovery in stage D. Else; the combustion will be regarded as an
incineration of the product and shall be accounted for as an environmental burden in stage C.
The energy recovery alternative includes an assessment where the marginal fuel that else would be
used on the market. This is in LCA referred to as system expansion and the LCA results depend on
which marginal fuel that is assumed to be displaced. To give the user of the EPD an understanding of the
consequences on different energy recovery options and the relative difference between these, it is
mandatory to report at least three scenario options. These options are;
 current practice;
 worst case;
 best case.
The current practice describes the marginal fuel on the market that the EPD shall be representative for.
The current practice is normally based on verifiable information. If such current practice cannot be
established a conservative approach shall be used. In this case, it shall be stated in the EPD that current
practice could not be defined and a description on the assumptions made shall be given briefly. Details
shall be reported in the LCA report and ICT/BIM communication format as defined in Table 14. Besides
current practice, a realistic worst case and best case shall be reported. The user of the EPD will then
understand the potential gains between reported alternatives. This scenario matter could also be
handled within a sub-oriented PCR and submitted for open consultation to branches outside the own.
The energy recovery option for stage D includes the following modules:
 D-ER1 Upgrading, treatment; includes all processing performed that is made before the discard
product may be sold as a fuel on the market, which may is defined by the current market for which
the EPD shall be representative for. This module continues where stage C ends and might include
additional transportation and several manufacturing sites and processes;
 D-ER2 Displaced fuel – current practice describes the environmental impact related to the displaced
fuel following the same life cycle scope as used in D-MR1;
 D-ER3 Displaced fuel – best case current practice describes the environmental impact related to the
displaced fuel following the same life cycle scope as used in D-MR1;
 D-ER4 Displaced fuel – worst case current practice describes the environmental impact related to
the displaced fuel following the same life cycle scope as used in D-MR1;
 D-ER Net impact – current practice. The net summed environmental impact from ER1 minus ER2,
covering the defined products life cycle according to the current practice scenario.

above, in the EPD.
LCA methods used for this life cycle stage shall be reported separately in public available literature and
referred to in the EPD. Different methods might be used why comparison between different EPD might
not be applicable and shall be stated in the EPD. If a method is used established in a Sub-oriented PCR it

5.2.5 Criteria for the inclusion and exclusion of inputs and outputs
Criteria for the exclusion of inputs and outputs (cut-off rules) in the LCA and information modules and
any additional information are intended to support an efficient calculation procedure. Cut-off rules shall
be defined in a way that has the minimum influence on the result obtained. They shall not be applied in
order to hide data. Any application of the criteria for the exclusion of inputs and outputs shall be
documented.
When impacts are assessed and reported, the cut-off rules shall be based on the environmental impacts
related to the respective material flows. The cut-off rules shall be justified and documented in the PCR.
The following procedure shall be followed for the inclusion and exclusion of inputs and outputs:
 All hazardous and toxic materials and substances shall be included in the inventory and the cut-off
rules do not apply;
 All inputs and outputs to a (unit) process shall be included in the calculation, for which data are
available. Data gaps may be filled by conservative assumptions with average or generic data. Any
assumptions for such choices shall be documented;
 In case of insufficient input data or data gaps for a unit process, the cut-off criteria shall be 1 % of
renewable and non-renewable primary energy usage and 1 % of the total mass input of that unit
process. The total of neglected input flows per module, e.g. per module A1-A3, A4-A5, B1-B5, B6-B7,
C1-C4 and modules in stage D (see Figure 3) shall be a maximum of 5 % of energy usage and mass.
Conservative assumptions in combination with plausibility considerations and expert judgement
can be used to demonstrate compliance with these criteria;
55
ISO/CD 21930
 Particular care should be taken to include material and energy flows known to have the potential to
cause significant emissions into air and water or soil related to the environmental indicators of this
standard. Conservative assumptions in combination with plausibility considerations and expert
judgement can be used to demonstrate compliance with these criteria.
5.2.6 Selection of data and data quality requirement
The data quality has an influence on the content of an EPD. As a general rule, specific data derived from
specific production processes or average data derived from specific production processes shall be the
first choice as a basis for calculating an EPD. In addition, the following rules apply:
 An EPD describing a specific product shall be calculated using specific data for at least the processes
the producer of the specific product has influence over. Generic data may be used for the processes
the producer cannot influence e.g. processes dealing with the production of input commodities, e.g.
raw material extraction or electricity generation, often referred to as upstream data (see Table 15);
 A specific EPD covering all life cycle stages (cradle to grave) may be calculated using generic data
for some downstream processes e.g. waste incineration. For the sake of comparability the
calculation of the use stage shall be based on the same additional technical information as is
required in 4.6;
 An EPD describing an average product shall be calculated using representative average data of the
products declared by the EPD, see Table 16;
 The additional technical information for the development of scenarios of the building’s life cycle
stages shall be specific or specific average information, when an average product is declared;
 Documentation of technological, geographical and time related representatives for generic data
shall be provided in the project report;
 Measured emission data – use foreground and background;
 For all types of average EPD the declaration shall include a description of what the EPD represents:
 Similar products included in the calculation of a manufacturer declaration (see 4.3.2.3: 1c1d) should not differ in their environmental impacts by more than +/-10% from the
reported average value for each impact category. In the case where this rule is not met, it is

5.3 Inventory analysis
5.3.1 Data collection
Data collection shall follow the guidance provided in EN ISO 14044:2006, 4.3.2.
5.3.2 Calculation procedures
The calculation procedures described in EN ISO 14044 shall apply. The same calculation procedures
shall be applied consistently throughout the study.
When transforming the inputs and outputs of combustible material into inputs and outputs of energy
the net calorific value of fuels shall be applied according to scientifically based and accepted values
specific to the combustible material.
5.3.3
Allocation of input and output flows
5.3.3.1 General
Most industrial processes produce more than the intended product. Normally, more than one input is
needed to produce one product and sometimes products are co-produced with other products. As a rule
the material flows between them are not distributed in a simple way. Intermediate and discarded
products can be recycled to become inputs for other processes. When dealing with systems involving
multiple products and recycling processes, allocation should be avoided as far as possible. Where
unavoidable, allocation should be considered carefully and should be justified.
In this standard, the rules for allocation are based on the guidance given in EN ISO 14044:2006, 4.3.4.
However, the basic procedures and assumptions used in EN ISO 14044 have been refined in order to
reflect the goal and scope of this standard.
The use of upstream data, which does not respect the allocation principles described in this standard
shall be clearly stated and justified in the project report. These data shall be in line with EN ISO 14044
allocation rules.
The principle of modularity shall be maintained. Where processes influence the product’s
environmental performance during its life cycle, they shall be assigned to the module in the life cycle
where they occur (see Figure 3).
The sum of the allocated inputs and outputs of a unit process shall be equal to the inputs and outputs of
the unit process before allocation. This means no double counting or omission of inputs or outputs
through allocation is permitted.
5.3.3.2 Co-product allocation
Allocation shall be avoided as far as possible. This may be done by dividing the unit process in a given
information module to be divided into different sub-processes that can be distributed to the coproducts.
 If a process can be sub-divided, but respective data are not available, the inputs and outputs should
be partitioned between its different products or functions in a way which reflects the underlying
physical relationships between them; i.e. they shall reflect the way in which the inputs and outputs
are changed by quantitative changes in the products or functions delivered by the system.
In the case of joint co-production, where the processes cannot be sub-divided, allocation shall respect
the main purpose of the processes studied, allocating all relevant products and functions appropriately.
59
ISO/CD 21930
The purpose of a plant and therefore of the related processes is generally declared in its permit and
should be taken into account. Processes generating a very low contribution to the overall revenue may
be neglected. Joint co-product allocation shall be allocated as follows:
 Allocation shall be based on physical properties (e.g. mass, volume) when the difference in revenue
from the co-products is low;
 In all other cases allocation shall be based on economic values;
 Material flows carrying specific inherent properties, e.g. energy content, elementary composition
(e.g. biogenic carbon content), shall always be allocated reflecting the physical flows, irrespective of
the allocation chosen for the process.
NOTE 1
Contributions to the overall revenue of the order of 1% or less is regarded as very low. A difference in
revenue of more than 25 % is regarded as high.
NOTE 2
A common position on the definition on the most appropriate allocation rule needs to be defined
together with other relevant sectors.
NOTE 3
Products and functions are the outputs and/or services provided by the process, having a positive
economic value.
NOTE 4
In industrial processes there may be a wide variety of different types of materials produced in
conjunction with the intended product. In business vocabulary, these may be identified as by-products, coproducts, intermediate products, non-core products or sub-products. In this International Standard, these terms
are treated as being equivalent. However, for the allocation of environmental aspects and impacts a distinction
between co-products and products is made in this standard.
5.3.3.3 Allocation procedure for reuse, recycled material and energy recovery
Historical loads and benefits from recycled material used as input to any process in stage A to C shall
not be allocated to the current product system. Inherent properties shall, however, not be allocated
away. Consequently, no bonus from such future material recycling, beyond the product system under
study, is accounted for in stage A to C.
Reuse is not included in stage A to C. Reuse is accounted for in stage D and handled in the same manner
in stage A to C as material recycling described above. This means that impact from the first use of the
product will not be allocated to downstream future use of the product.
Energy recovery is handled as co-product allocation in stage A to C. Materials for energy recovery are
identified based on the efficiency of energy recovery with a rate higher than 60 % without prejudice to
existing legislation. Materials from which energy is recovered with an efficiency rate below 60% are not
considered materials for energy recovery. Such impact shall be assign to the product under study.
The end-of-life system boundary of the construction product system is set where outputs of the system
under study, e.g. materials, products or construction elements, have reached the end-of-waste state.
Waste processing of the material flows (e.g. undergoing recovery or recycling processes) during any
module of the product system (e.g. during the production stage, use stage or end-of-life stage) are
included up to the system boundary of the respective module as defined above.
Environmental potential loads and benefits of secondary material, secondary fuel or recovered energy
from the scraped product is handled in stage D as supplementary information, and is defined in section
5.2.4.6.

ISO/CD 21930
5.3.4 Accounting of biotic carbon during the life cycle
Renewable materials (wood, linen, cork etc or biogenic manufactured polymers) contain biotic carbon
that originates from living organisms. This material flow shall be reported as inherent CO 2 bio when
entering the product system (i.e. a flow to technosphere from nature). This biotic carbon flow will be
reported as a negative CO2 bio value in the LCI, since it represents a coal source that is part of a
renewable circulation. When this biotic carbon material – partly or as a whole – is transformed to
emissions, it will then be accounted for as emitted as CO2 bio. The overall CO2 bio balance will therefore
always be zero when a full life cycle is accounted for. These two specifications represent the system
boundary between nature and the product system. In addition, if the biotic carbon accounted for enter a
new product system after end-of-life (after module C), this transformation will be reported as a positive
CO2 bio value in module C. Therefore, product that is recycled or energy recovered in future will result in
a zero value, when this inventory flow is added for the whole life cycle (A to C). Consequently, a product
that is use biotic recycled material shall report a negative CO2 bio representing the inherent biotic carbon
content when entering the product system.
NOTE 1
the LCI.
A biotic material also has an energy content as an inherent property that is accounted for separately in
NOTE 2
This system boundary is valid for all life cycle stages from A to C.
NOTE 3
CO2 bio shall not be reported as CO2e since it is not an LCIA result.
NOTE 4
When a biotic material is transformed to emissions other emissions than CO2 they shall be accounted
for in the LCI and evaluated in the LCIA.
5.3.5 Accounting of delayed emission of biotic carbon – biotic carbon sinks
In respect to climate change it is essential to reduce the peak emission of greenhouse gases. A
construction product that contain biogenic carbon sink may contribute to this matter. There is a few
method suggested to handle this matter and report the result as CO2e. Since a common acceptance of
such LCIA method is lacking, this indicator result is not part of the LCA result in the EPD and has to be
reported under “Additional information” if included. However, the biotic carbon sink may be optionally
reported in the EPD for construction products in B1 as “x kg CO2 bio stored for y years”.
NOTE 1
A noticed applied method for accounting of delayed emission of biotic carbon is defined in climate
footprint system PAS 2050, which also referred to and part of the LCIA indicators in the EC environmental
declaration system; Product Environmental Footprints (PEF).
5.3.6 Land use change
Land transformation or land use change accounts for the purpose for which land is used by humans and
may include several environmental aspects where effects on climate change are commonly reported.
Different international valid factors for land use change are given by Intergovernmental Panel on
Climate Change (IPCC); Good Practice Guidance for Land Use, Land-Use Change and Forestry (GPGLULUCF). The reporting under forest management is strongly linked to the reporting of ‘Forest land
remaining forest land’ under the UNFCCC-reporting.
In addition and when significant, the greenhouse gases emissions occurring as a result of the land use
change it should be assessed in accordance with internationally recognised methods such as the
Intergovernmental Panel on Climate Change (IPCC) Guidelines for National Greenhouse Gas Inventories.
These GHG emissions shall be included in the LCI and LCIA and documented separately in the LCA
report. Double-counting shall be avoided.
NOTE 1
This aspect is not restricted to biogenic materials but also all other of materials and processes.
61
ISO/CD 21930
NOTE 2
Wood from well managed forestry’s may be accounted for zero emission concerning land use change,
since this as assumed to be a conservative approach since the indirect ground soil carbon normally is a net
contributor of a carbon pool in the forestry system.
5.3.7 Calcination and carbonation of pozzulane materials
A pozzulane is a material (like cement, fly ash etc.) with a capability of reacting with calcium hydroxide
(Ca2+ or Ca(OH)2) in the presence of water. Such material has an inherent potential to carbonate in any
downstream life cycle stage when the material is in contact to air. Inapproachable of the co-product
allocation method applied the inherent potential possible to carbonate cannot be allocated away and
will be allocated to the product system where it appears. Consequently, the calcination will always be
the same or larger than the reported carbonated CO2 in the context of LCA.
These kind of process related greenhouse gas emissions would always be reported as part of the
common LCIA indicator for climate change (i.e. as CO2e) and reported separately in the LCA report.
Established theoretical methods for calculation of the carbonation exist and may be applied.
NOTE 1
It is possible in e.g. a sub-oriented PCR to establish commonly valid intended use application to
simplify the calculation on carbonation on a generic level. Suck simplified approach will always be based on
scenarios and therefore only an example on how it might be.
5.3.8 Inventory indicator describing energy resource use
The declaration of use of energy recourses – primary and secondary - shall be carried out for the
parameters given in Table C.4 and Table C.5 specified for all modules. The parameters are as:
1) Renewable primary energy used as an energy carrier (fuel); RPEE is all (first time used)
biological materials used as an energy source. Also hydropower, solar and wind power used in
technosphere belong here.
2) Renewable primary energy used as material; RPEM is (first time used) biological materials
used as materials (Wood, hemp, etc.).
3) Non-renewable primary energy used as an energy carrier (fuel); NRPEE is materials such as
peat, oil, gas, coal, uranium.
4) Non-renewable primary energy used as materials; NRPEM are primary resources (with an
energy content) such as oil, gas and coal, which later ends as products like plastic materials or
animal feed.
5) Secondary materials; SM are materials recycled from previous use or waste (scrap metal,
broken concrete, broken glass, plastic) which are used as material. Could be both renewable and
non-renewable, with or without energy content.
6) Renewable secondary fuel; RSF are renewable materials with an energy content, which have
been used previously or are defined as waste, which are used as energy source (biomass
residue, waste wood).
7) Non-renewable secondary fuels; NRSF are non-renewable materials with energy content,
which have been used previously or are defined as waste, which are used as an energy source
(solvents, tires).
62

ISO/CD 21930
Cumulative energy demand (CED) shall be reported based on both renewable and non-renewable
energy resources as given in Table B.1.
CEDR is given as sum of RPEE and RSF for materials used as energy carrier (not used as material).
CEDNR is given as sum of NRPEE and NRSF for materials used as energy carrier (not used as material).
5.3.9 Inventory indicator describing net use of fresh water
Net use of fresh water shall be calculated and reported.
Net Use of Fresh Water should follow the approach of ISO/DIS 14046.2:2013.
5.3.10 Environmental information describing waste categories and outflows derived from LCA
The parameters describing waste categories and other material flows are output flows derived from the
LCI.
The waste categories given in Table 17 shall be declared and specified for all information modules
included in the EPD. In Table C.6 the format for declaration of waste in the ITM is given and may be
used as format in the EPD.

The parameters in Table 17 are calculated on the gross amounts leaving the system boundary when
they have reached the end-of-waste state as described in Table C.7.
The output flows given in Table 18 shall be declared and specified for all information modules included
in the EPD. In Table C.7 the format for declaration of output flows in the ITM is given and may be used
as format in the EPD.

The parameter “Materials for energy recovery” does not include materials for waste incineration.
Waste incineration is a method of waste processing and is allocated within the system boundaries. Waste
incineration plants have a lower energy efficiency rate than power stations using secondary fuels. Materials for
energy recovery are based on thermal energy efficiency rate of the power station not less than 60 %.
5.4 Impact assessment; Parameters describing main environmental impacts derived
from LCA
The impact assessment shall be carried out for the impact categories GWP, ODP, AP, EP, POCP and
ADPfossil, ADPelement specified for all modules included as given in Table C.2.
Characterisation factors given in references in Table 19 for GWP, ODP, AP, EP, POCP and ADP shall be
used.

The abiotic depletion potential is calculated and declared in two different indicators:
ADPelement include all non-renewable material resources (minerals, uranium, sulphur) used as energy
and material.
ADPfossil include all non-renewable fossil resources indicators (coal, oil, fossil gas) used as energy and
material; sum of TNRPE (Total use of Non-Renewable Primary Energy resources), for all modules given in
Table B.1.
NOTE 1
It is considered good practice to identify LCI data that has no calculated environmental impact within
the project report. This can help to identify the need for complementary and consistent characterisation factors
for relevant LCI flows.
NOTE 2
ADPfossil will always be equal to or less than total use of non-renewable primary energy resources
(TNRPE), in Table C.4 as sulphur and uranium are not included in ADP fossil.

with respect to occupant health at the building level. When developing sub-category PCR, specific
requirement shall be given.
 Emissions to indoor air shall be declared according to standards applicable in the market for which
the EPD is valid. The reporting is based on measurement of release of dangerous substances from
construction products using harmonised test methods.
6.1.1 Volatile, semi-volatile and very volatile organic compounds
The reporting format for declaration of VOC emissions given in Table 20 shall be used.
Reporting on VOC according to this format is intended for all products that may be exposed to interior
spaces and/or within the building envelope.
NOTE 1
The building envelope consists of the roof, exterior walls and floor of a structure. These elements form
a barrier that separates the interior of the building from the outdoor environment
NOTE 2
Where post-manufacture coatings or surface applications have not been applied, the following floor,
ceiling and wall systems are deemed to comply with the requirements: ceramic and concrete tile, organic-free
mineral-based materials, gypsum plaster, clay masonry, concrete masonry, concrete, and metal.

The R-value (Risk-value) is derived by summarizing the individual Ri-values. The Ri value is the ratio of
the emission concentrations of individual compounds in the mixture (Ci) divided by the corresponding
lowest concentration of interest value (LCIi); Ri = (Ci/LCIi).
R-value = Σ(Ri + …Rn)

ISO/CD 21930
The R-value approach assuming dose additivity of all compounds in a chemical mixture irrespective of
their health effects. Applied LCIi values are given in Annex D and are mandatory, but may be
complemented with other data sets.
Measured product specific VOC emission values, Ci, are derived from chamber tests.
NOTE 3
This standard suggests using CEN/TS 16516 or likewise methods, as specification for such horizontal
testing method. CEN/TC 16516 is based in ISO 16000 standard series, but contains additional refinements for
improving reliability and has gone through extensive validation.
6.1.2 Particulate matter
Currently no recognised methods is found on realize of particulates matters. However, this will be taken
into account in future revision of this standard.
6.2 Release of dangerous substances to soil and water during the life cycle
Emissions from material may be measured as a material and substance specific property via different
laboratory tests. Such data will serve as input for estimation of release of emissions in different
intended use applications. Dependant on the type of material and its structure, column or batch test are
used for granular material and serial batch leaching tests (also known as tank tests) for monolith
materials. Batch test shall in this context be regarded as proxy for column tests. The common approach
with these methods is that a declining emission will occur in relation to the amount of water available in
respect to the material exposed. Test method/-s required on different markets shall be utilised and the
method/-s applied shall be reported in the EPD.
NOTE 2
Work is currently going on in Europe by CEN TC 351 on a package of tests methods relevant for the
reporting defined here.
The laboratory tests is the basis for scenario based calculation some emission. Information on release of
emissions to soil and water may be relevant for input to the LCA in life cycle stages A1-3, A5, B1 and C4.
These emissions can also be used for risk assessment or to calculate a simplified R-factor (as outlined
above for indoor air). It is likely that such development take place in future. The difference compared to
the indoor air emission that has only one unit room is that is that a number of representative
compartments for soil and water exposure have to be defied, and suck works exist but is not yet
standardised.
The reporting format as given in Table 21 shall be provided for products exposed to soil and water after
their installation in construction works during the use stage in order to support use stage scenarios for
soil and water pollution at the building level.

Since batch leaching test results are normally available at limited number of L/S values for which the
test is performed (typically L/S = 2 l/kg or 10 l/kg) and therefore may not correspond to the L/S value
at which the release is sought in the scenario. The result can be “translated” from one L/S value to
another by means of the kappa () relationship. From the leaching test, the leaching of several
substances may be expressed by a simple decay function:
C = C0 * e - (L/S) 
where C is the concentration of the contaminant as a function of L/S (mg/l), the constant C 0 is the initial
peak concentration of the contaminant in the leachate (mg/l), L/S is the liquid to solid ratio
corresponding to the concentration C (l/kg) and where  is a kinetic constant describing the rate of
decrease of the concentration as a function of L/S for a given material and a given substance (kg/l). C0
and  values may be estimated from column or serial batch leaching data. By integrating the above
expression, the amount of the substance, M (in mg/kg), released over the period of time it takes for L/S
to increase from 0 l/kg to the value corresponding to C, can be calculated:
M = (C0/)(1 – e - (L/S))
If an emission scenario is applied (based on the figures given in Table 21) in the LCA the release, M, and
significant scenario settings may be reported according to Table 22.

Communication formats
This clause defines the standardized part of the EPD communication i.e. the generic template. The
generic template is called an Information Transfer Matrix (ITM).
Communication of standardized environmental information for construction goods and services
requires a format that provides a location of all elements of information from different sources. The ITM
provides a unique and consistent reference position in a grid. The ITM will contain some information,
which is mandatory and some information, which is voluntary, and so in some cases blanks or gaps can
occur in the ITM.
The matrix provides the template for communicating this information for each of the information
modules as defined in Figure 2. The matrix is also used for communicating the information for any of
the scenarios, which can occur and/or the respective technical information for these scenarios. The ITM
consists of a grid structure in which all items of information according to this International Standard
shall be presented.
To present environmental information in a structured and consistent way and in a common format, a
generic template is used. The generic template is used for information transfer. The ITM:
 does not preclude the fact that an EPD can have an individual and unique format;
 is the standardized part of EPD communication according to this International Standard;
73
ISO/CD 21930
 a statement whether the ITM has been independently verified shall be made.
The ITM addresses the following types of information according to this International Standard:
— general information; see C.1;
— LCA results from life cycle impact assessment - LCIA:, see Table C.2;
— LCA results from life cycle inventory; see Table C.3 to C.7;
— environmental information not derived from LCA; see Table 20 and Table 21;
— scenarios and technical information; see Table 3 to Table 14;
— declaration of future reuse, material recycling and energy recovery (stage D); see Table C8 to Table
C.11;
— in any EPD the declaration of material content of the product shall list as a minimum substances
contained in the product that are identified as hazardous according to normative requirements in
standards or regulation applicable in the market for which the EPD is valid.

It is not required to make such confidential data publicly available.
Normally, the EPD present only data that have been aggregated over the four stages of the life cycle or
relevant portions of it and the aggregation obscures the underlying competitive information.
Confidential business data provided for the independent verification process can be kept confidential
upon request of the body supplying the data and with the approval of the programme operator, in
accordance with programme operational rules; see ISO 14025:2006, 8.3.

in the EPD as required in this standard. Such documentation on additional environmental information
may include, e.g. as copies or references:
 laboratory results/measurements for the content declaration;
 laboratory results/measurement of functional/technical performance;
 documentation on declared technical information on life cycle stages that have not been considered
in the LCA of the construction product and that will be used for the assessment of buildings (e.g.
transport distances, RSL according to Annex A, energy consumption during use, cleaning cycles,
etc.);
 laboratory results/measurements for the declaration of emissions to indoor air, soil and water
during the product’s use stage.
9.5 Data availability for verification
To facilitate verification it is considered good practice to make the following information available to
the verifier, taking into account data confidentiality according to ISO 21930:2007, 7.4 and 9.1:
 analysis of material and energy flows to justify their inclusion or exclusion;
 quantitative description of unit processes that are defined to model processes and life cycle stages

 documentation that substantiates the percentages and figures (number of cycles, prices, etc.) used
for the calculations in the allocation procedure, if it differs from the PCR.
10 Verification and validity of an EPD
After verification an EPD is valid for a 5 year period from the date of issue, after which it shall be
reviewed and verified. An EPD shall only be reassessed and updated as necessary to reflect changes in
technology or other circumstances that could alter the content and accuracy of the declaration. An EPD
does not have to be recalculated after 5 years, if the underlying data has not changed significantly.
The process for verification and establishing the validity of an EPD shall be in accordance with EN ISO
14025:2010.
77
ISO/CD 21930
NOTE 1
A reasonable change in the environmental performance of a product to be reported to the verifier is
+/- 10% on any one of the declared parameters of the EPD (see 5.2.6). Such a change may require an update of the
EPD.

ISO/CD 21930
Annex A (normative) Requirements and guidance on the reference service life
A reference service life (RSL) can only be determined for a cradle to grave EPD or a Cradle to Gate EPD
with options where modules A1-A5 and B1-B5 have been provided. If the service life is declared then
the following principles shall apply. The manufacturer or producer of the construction product cannot
be held responsible for the actual design of the building and the use and application of the product,
environment, workmanship or use.
 The reference service life of a product can be based upon empirical, probabilistic, statistical,
deemed to satisfy or research (scientific) data and shall always taking into account the intended use
(description of use), see ISO 15686-1, -2, -7 and -8. This basis shall be mentioned in the EPD;
 If the manufacturer provides the RSL for the product then he shall take into account and shall
describe in the EPD the intended use and declared functional performance(s) and the scenario. The
estimate shall be transparent to allow for verification.
A declared RSL shall be related to the declared functional technical performance and to any
maintenance or repair necessary to provide the declared performance during the declared RSL or
provided Estimated Service Life (ESL). The declared technical performance may be based on
specifications for determination or calculation of this performance given in the relevant harmonised
European standards. These performances may be defined as initial, average or minimum levels. See
Figure A.1 and A.2.
NOTE 1
The declared technical performance may be the input for calculations beyond this standard. However
the out-come in terms of RSL will be input for the requirements in this standard.
EXAMPLE 2
The thermal performance of a window, insulation, a heating boiler, etc. will impact on the energy
use of the building in the use stage. This energy use, its emissions and waste are contributing to the environmental
aspects and impacts of the building in the use stage. The RSL of the window, insulation, the heating boiler, etc.
needs to be linked to the product's performance in order to provide consistency in the calculation model.

Figure A.2 — Type of declared technical and functional performance, repair/maintenance

The RSL is dependent on the properties of the product and specific in-use conditions. These conditions
shall be declared together with a RSL and it shall be stated that the RSL only applies to these specific
conditions.
The description of the technical and functional performance of a product is required for the European
technical specifications for construction products. This description may be based on data collected as
average data or at the beginning or end of the service life. The reference conditions for achieving the
declared technical and functional performance and the declared reference service life shall include the
following, where relevant:
 declared product properties (at the gate) and those of any finishes, etc.;
 design application parameters (if instructed by the manufacturer), including references to any
appropriate requirements and application codes;
 an assumed quality of work,;
 external environment, (for outdoor applications), e.g. weathering, pollutants, UV and wind
exposure, building orientation, shading, temperature;
 internal environment (for indoor applications), e.g. temperature, moisture, chemical exposure;
 usage conditions, e.g. frequency of use, mechanical exposure;
 maintenance, e.g. required frequency, type and quality and replacement of replaceable components.
In many cases the Estimated Service Life (ESL) of the building depends on whether its components are
replaceable or repairable. Normally the ESL of a building depends on the service life of the load bearing
product or construction element that is not replaceable or repairable.
80
© ISO #### – All rights reserved
ISO/CD 21930
The RSL of a construction element (e.g. a window) declared in the EPD is dependent on the service life
of its individual components (handle, hinge, etc.) and may be determined by the component with the
lowest service life. It also depends on whether the single components of the construction element are
replaceable or repairable.
RSL data is normally based on direct testing or both direct and indirect data acquisition (see ISO 156862, ISO 15686-8 and ISO/TS 15686-9). Direct data acquisition may be based on:
 field exposure;
 inspection of buildings and their components;
 experimental buildings;
 in-use exposure.
In some cases for products for which direct data are not available indirect methods may be used for
establishing RSL:
 correlated to data for existing products of a similar type with similar functions having similar use
and exposure conditions;
 comparative data obtained by testing the products of a similar type and similar function for similar
uses and exposure conditions, in accordance with EN product test standards.
NOTE 2
ISO/TS 15686-9 refers to procedures that may be divided into two groups, direct and indirect tests.
Direct testing – the achievement of a certain level of performance in a test of a particular property is
recognised as being direct evidence of expected service life (e.g. abrasion, fatigue, closing, and impact
tests).
Indirect (proxy) testing – the measurement of “proxy” characteristics that can be correlated to actual
performance and hence service life (e.g. porosity for freeze-thaw resistance and hardness for abrasion
resistance).
Tests may be either:
 Natural weathering/ageing tests, which either give a direct indication of service life (e.g. corrosion
tests) or enable normal performance tests to be carried out after treatment, thus allowing the likely
degradation under in-use conditions to be determined;
 Accelerated weathering/ageing tests, in which the normal ageing process is speeded up to reduce
the duration of the test. Care is needed to ensure that degradation mechanisms are just accelerated
and not significantly altered in such tests.
Tests may be long-term or short-term, or a combination of both.
Long-term tests may include:
a) field exposure;
b) exposure in experimental buildings.
Short-term tests may include:
81
ISO/CD 21930
c) accelerated short-term tests;
d) short-term in-use exposures.
