Compliance
ENERGY STAR
Definition
A voluntary U.S. EPA energy efficiency program that provides performance ratings and certification for commercial buildings (scores 1–100), homes, appliances, and industrial equipment. Buildings scoring 75 or above on the ENERGY STAR 1–100 scale can apply for ENERGY STAR certification.
Why It Matters for Your Business
ENERGY STAR-certified commercial buildings use on average 35% less energy than similar buildings. The certification is recognized by tenants, investors, and appraisers as a marker of quality, often supporting higher rents and occupancy rates. It's also required or preferred for many federal and state incentive programs.
Frequently Asked Questions
How is the ENERGY STAR score calculated?
EPA's Portfolio Manager calculates a 1–100 percentile score comparing a building's source EUI against similar buildings in the CBECS (Commercial Buildings Energy Consumption Survey) database, normalized for weather, occupancy, and operating hours. A score of 50 = median; 75+ = top quartile.
What buildings are eligible for ENERGY STAR certification?
Over 20 building types are eligible, including offices, retail, hotels, hospitals, schools, warehouses, and multifamily housing. Not all building types have an eligible scoring model. Check energystar.gov/buildings for current eligible types.
