The U.S. Department of Energy (DOE)’s Building Energy Asset Score (Asset Score) is a national standardized tool for assessing the physical and structural energy efficiency of commercial and multifamily residential buildings. The Asset Score generates a simple energy efficiency rating that enables comparison among buildings, and identifies opportunities to invest in energy efficiency upgrades. It is available for voluntary use and is 100% free to use.


This project supports additional DOE initiatives, such as the Better Building Challenge. A primary market barrier to implementing energy efficiency strategies is that building owners and investors lack a reliable source to understand building as-built efficiency and a low-cost means to identify opportunities for cost-effective improvements. The Asset Score reflects the energy efficiency of a building based solely on its design, construction, and energy systems. The Asset Score normalizes for operational and occupancy factors, enabling users to identify specific opportunities to invest in asset-related energy upgrades.
