SUSTAINABILITY TOOLS
FOR INTEGRATED DESIGN
Whole Building Design
 Provides the strategies to achieve a true high-performance building: one
that is cost-effective over its entire life cycle, safe, secure, accessible,
flexible, aesthetic, productive, and sustainable.
the ease of maintenance,
global climate change,
operating costs, fuel choice,
the type of lighting and
controls used, how much
natural daylight is brought in,
how the space is organized,
the facility's operating hours,
and the local microclimate.
aesthetics, accessibility, and
security of the project
A successful Whole Building Design is a solution that is greater than the sum of its parts.

What is Building Performance
Simulation
Complex and rigorous calculations of the
energy processes within a building using
computer models
Advanced software packages are capable of
calculating building energy performance hour
by hour for an entire year
31
Why We Need Building Performance
Simulation
Powerful tool to analyze how form, size,
orientation and type of building systems affect
overall energy performance
For optimizing:
Energy
Lighting/Day Lighting
HVAC Design/IAQ/Natural Ventilation/Airflow
Evaluating costs
Code compliance – LEED, Title 24, ECBC etc
