What does an ENERGY STAR score of 83 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 83 means the building performs better than about 83% of its national peers. BuildingCensus bands the score into report-card grades; 83 falls in band B — above median (70–84). 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. 1M Street Properties LLC's 57.3 kBtu/ft² across 128,575 sq ft works out to about 7.4 billion Btu (2,159 MWh-equivalent) in 2024. Its source EUI of 160.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,159,084 kWh of electricity, 0 therms of natural gas and 2,226 thousand gallons of water for the year.
