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 m
icroclimate.
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
