Whole systems approach
•  Solving a systemic problem requires a holistic
approach
•  Systems thinking = holistic approach
•  Integrative design uses systems thinking
© Climate Resources Exchange (2014) Pte Ltd

The whole systems approach to
reducing capital and operating costs
•  High performance design deals with a complex web of
interrelated issues
•  This complexity cannot be addressed through a “broad
brush-stroke” or single issue approach
•  Efficiency requires “designing out” technical complexity and
cost by carefully rethinking, challenging and improving
•  A well-defined, collaborative, integrated multi-disciplinary
team process is essential

Whole systems thinking
•  The process of understanding how things
influence one another within a whole
o  In nature, various elements must work
together in ecosystems
o  In buildings, all the components that
make up the building must work
together
•  Solve ‘problems’ by viewing them as parts of an
overall system, rather than reacting to specific
parts, outcomes or events
o  Piecemeal approach potentially creates
unintended consequences. An improvement
in one area of a system can adversely affect
another.
o  Small catalytic events can cause large
changes in complex systems

Whole systems thinking
•  Most people think that efficient
systems are about energy
efficient equipment and
expensive gadgets.
•  This is like saying that using the
best ingredients will ensure a
tasty dish.

Whole systems thinking
But the finest ingredients won't make
our dish tasty unless:
•  We use a good recipe
•  The recipe combines the
right ingredients…
•  …in the right manner and
proportions

What is IDP?
•  IDP is the most effective process for exploring and
implementing sustainable design principles on a project while
staying within budget and program schedule constraints.
•  The process is essential to achieving high performance
(sustainable) buildings while avoiding or minimizing
incremental costs
•  Requires a multi-disciplinary and collaborative team
•  Follows the design through the entire project life, from predesign through occupancy and into operation
•  Can be used for both new and existing buildings. Don’t
replicate the old mistakes.
•  LEED/Green Mark is not the same thing as IDP

Factor Ten Engineering (10xE)
•  Factor Ten Engineering (10xE) aims to help engineers, architects and
their clients attack resource-intensive design problems, such as
manufacturing/industrial processes and facilities using whole-system
principles in order to produce fundamentally better results.
•  10xE currently offers design principles and a growing set of case studies
over several projects and as pioneered by RMI. Rather than a rigid
formula, 10xE is a set of ideas for shaping the design space and design
approaches within it. These ideas will be used by those purchasing or
approving design services, as well as design practitioners.
•  CRX facilitates the exchange of expertise by and between the design
team and consultants. The approach also allows for solutions to be
presented at the outset to be followed through from construction
through operations.

The Differences
Integrative Design Process
vs
Conventional Design Process
Inclusive from the outset vs
Involves team members only when essential
Front-loaded — time and energy invested early vs
Less time, energy, and collaboration in early
stages
Decisions influenced by broad team vs
Iterative process vs
Whole-systems thinking vs
Allows for full optimization vs
Seeks synergies
vs
Life-cycle costing vs
Process continues through post-occupancy vs
Source: Roadmap for the
Integrated Design Process
More decisions made by fewer people
Linear process
Systems often considered in isolation
Limited to constrained optimization
Diminished opportunity for synergies
Emphasis on up-front costs
Typically finished when construction is complete

14
LEED/Green Mark
is not the same thing as
an Integrative Design Process
Often the team’s only purpose is to achieve
LEED points
•  The architecture is designed separately,
without the engineer’s input concerning
its energy performance
•  Energy modeling is done only to get the
point, rather than to inform design
decisions
•  Commissioning is often an afterthought
•  Etc.

Bank of America in NYC –
The New Republic Magazine
July 28, 2013 “What LEED designers deliver is what most
LEED building owners want—namely, green publicity, not
energy savings,” John Scofield, a professor of physics at
Oberlin, testified before the House last year.
Governments, nevertheless, have been happy to rely on
LEED rather than design better metrics. Which is why New
York’s release of energy data last fall was significant.
It provided more public-energy data for a U.S. city than
has ever existed. It found the worst-performing buildings
use three to five times more energy per square foot than
the best ones.
It also found that, if the most energy-intensive large
buildings were brought up to, the city’s total greenhouse
gases could be reduced by 9 percent" the current
seventy-fifth percentile

Performance Metrics
Importance of Integrative Design Process
•  Early feedback from engineers informs the design process
•  Building performance metrics set clear indicators for
evaluating competing design solutions
•  Load reduction measures can be exploited in sizing and
selection of equipment (offsetting cost of premium
elements)

sustainable building, uses 50% more energy than it was designed
to do.”

Example: Reduction in fan power
Airflow rate = 180m3/h
Diameter of duct 100mm
Velocity =6.5m/s
Pressure loss =7.0Pa/m
If duct diameter increased to 150mm
Velocity =2.9m/s
Pressure Loss = 0.9Pa/m
A 50% increase in duct diameter results in a 90% reduction in
duct pressure loss, this will deliver:
A 4 to 5 fold reduction in fan power!

What does this mean in terms of reduced OPEX?
Example:
Air Handling Unit (AHU)
•  Fan motor size reduced from 27.5 kW to 15.3 kW
• 
Saves 106,800 kWh/year
•  Operating cost reduction = S$ 26,000/year
(@ 24 c/kWh)
