What does an ENERGY STAR score of 97 mean?

ENERGY STAR scores run from 1 to 100 and are computed by the EPA's Portfolio Manager as a percentile against similar buildings nationwide, adjusted for climate, size and use: a score of 97 means the building performs better than about 97% of its national peers. BuildingCensus bands the score into report-card grades; 97 falls in band A — high performer (85–100). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. In Washington, DC, 47% of scored buildings are at 75 or above.

Site energy-use intensity (EUI) is the energy a building uses on site in a year divided by its floor area, in thousand Btu per square foot — lower is more efficient. Woodley Plaza Condominium's 28.4 kBtu/ft² across 79,517 sq ft works out to about 2.3 billion Btu (662 MWh-equivalent) in 2024. Its source EUI of 79.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 661,299 kWh of electricity, 0 therms of natural gas and 1,956 thousand gallons of water for the year.

Which law requires Woodley Plaza Condominium to report its energy use?
