What does an ENERGY STAR score of 66 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 66 means the building performs better than about 66% of its national peers. BuildingCensus bands the score into report-card grades; 66 falls in band C — below median (55–69). It sits 9 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. 2615-2619 42nd St. NW's 65.2 kBtu/ft² across 29,960 sq ft works out to about 2 billion Btu (572 MWh-equivalent) in 2024. Its source EUI of 85.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 83,008 kWh of electricity, 16,691 therms of natural gas and 971 thousand gallons of water for the year.

Which law requires 2615-2619 42nd St. NW to report its energy use?
