Optimize energy performance

Intent

Achieve increasing levels of energy performance above the prerequisite standard to reduce environmental impacts associated with excessive energy use.

Requirements

Demonstrate the EPA ENERGY STAR energy performance rating that the building has achieved. Utilize ENERGY STAR’S Portfolio Manager tool for building types addressed by ENERGY STAR,

For building types not addressed by ENERGY STAR, demonstrate the ENERGY STAR equivalent rating for the building energy use, calculated using the alternate method described in the LEED for Existing Buildings Reference Guide.
