What does an ENERGY STAR score of 13 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 13 means the building performs better than about 13% of its national peers. BuildingCensus bands the score into report-card grades; 13 falls in band D — lowest band (1–54). It sits 62 points below 75, the threshold for ENERGY STAR certification. 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. 1010 Massachusetts Avenue Condominium's 87.0 kBtu/ft² across 204,045 sq ft works out to about 17.8 billion Btu (5,203 MWh-equivalent) in 2024. Its source EUI of 151.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,053,097 kWh of electricity, 107,470 therms of natural gas and 2,224 thousand gallons of water for the year.

Which law requires 1010 Massachusetts Avenue Condominium to report its energy use?
