What does an ENERGY STAR score of 94 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 94 means the building performs better than about 94% of its national peers. BuildingCensus bands the score into report-card grades; 94 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. Macomb Gardens Apartments (mc061)'s 56.7 kBtu/ft² across 60,984 sq ft works out to about 3.5 billion Btu (1,013 MWh-equivalent) in 2024. Its source EUI of 87.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 280,515 kWh of electricity, 25,009 therms of natural gas and 3,403 thousand gallons of water for the year.

Which law requires Macomb Gardens Apartments (mc061) to report its energy use?
