The Energy Star designation means the building performs in the top 25% of similar facilities nationwide for energy efficiency. The award was presented on June 28 during ASHRAE's 2010 Annual Conference by Jean Lupinacci, chief of the Energy Star Commercial & Industrial Branch.
Commercial buildings that earn the ENERGY STAR use an average of 35% less energy than typical buildings and also release 35% less carbon dioxide into the atmosphere. ASHRAE improved its energy performance by managing energy strategically across the entire organization and by making cost-effective improvements to its building. ASHRAE has prevented greenhouse gas emissions equal to the electricity use from nearly 22 households for a year.
The national average site energy use index (EUI) is 68 and average source EUI is 228. ASHRAE's site energy intensity is 49 and source is 162.
