## Why Consider a “Green” Building and LEED?

**Can achieve lower first cost.**
**Advanced thermal envelope can significantly reduce heating and cooling equipment sizes.**
**Lower long term operating and maintenance costs.**
**Longer life of the building and finishes.**
**Improved worker comfort and productivity.**
**Significant image and good will benefits for the entity.**
**Lowered impact on the environment.**
**LEED is the only nationally recognized objective standard to rate Green building designs.**
