What does an ENERGY STAR score of 89 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 89 means the building performs better than about 89% of its national peers. BuildingCensus bands the score into report-card grades; 89 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. Mass Court - Municipal Benchmarking Account's 36.9 kBtu/ft² across 363,927 sq ft works out to about 13.4 billion Btu (3,936 MWh-equivalent) in 2017. Its source EUI of 99.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,086,503 kWh of electricity, 28,991 therms of natural gas and 15,835 thousand gallons of water for the year.
