Frequently asked questions

Which large Washington, DC buildings have the worst energy grades?

Washington Hospital Center reports the lowest ENERGY STAR score (1) among Washington, DC buildings over 50,000 sq ft. DC's Building Energy Performance Standards (BEPS) require buildings below the performance standard to improve on 5-year compliance cycles, with penalties for buildings that fail to meet their pathway.

Does a low score mean the building breaks the law?

No. A low ENERGY STAR score is a national efficiency percentile, not a violation. It does correlate with exposure under building-performance standards (carbon caps, retrofit mandates), which is why owners, lenders and retrofit contractors watch these lists.
