HOLISTEEC concept
The main objective is to design, develop, and demonstrate a BIM-based, on-the-cloud,
collaborative building design software platform, featuring advanced design support for
multi-criteria building optimization, taking into account external neighbourhood-level
influences

Performance-based methodology
Performance based design approach emphasizes the setting of project targets as
functional targets of end product (building) and evaluation of fulfillment of these
targets during design, construction and operation (CIB, 1982)
HOW BUILDING PERFORMANCE is considered within HOLISTEEC
BIM-based software platform
 DEDICATED CALCULATION ENGINES for building
performance SIMULATION
 MULTI-PHYSICAL SIMULATION ENGINE enabling the
combination of the results coming from the different
calculation engines by means of a multi-criteria analysis,
thus providing the platform end-users with a quantitative
measurements of the quality of the implemented design
solution

Dedicate calculation engines
Currently experience and knowledge of the designers are used as a basis to choose
design global optimum  the goal for HOLISTEEC is to transfer designers’ knowledge
and experience in the software design decision tools, in order to provide
recommendations to designers based on empirical, formalized design expertise.
Simulation tools starting from concept design phase
• Energy calculation engine
• Acoustic calculation engine
• Environmental impact engine
• Lighting calculation engine

Key Performance Indicators
Assessment of the process
performance
Comparison among different
performances
Communication in a concise and
understandable way process
achievements
In the framework of HOLISTEEC BIM based software PLATFORM:
Strategic importance of KPI in order to assess the quality of the results coming
from the building performance simulations

Multi-physical simulation engine
 Multi-physical simulation engine completed by a design assistant, providing online
recommendations to the designer, enabling a semi-automated approach to design.
This tool will be based on a multi-criteria analysis enabling the assessment of the
building with respect to the identified KPIs for each domain of interest.

KPI Scoreboard
 Will provide assistance during
design (options, missing data,
risk analysis…)
 Intuitive visualization of
performance indicators of the
various design options
