What does an ENERGY STAR score of 87 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 87 means the building performs better than about 87% of its national peers. BuildingCensus bands the score into report-card grades; 87 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 New York City, 43% 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. 42-11/45 Corporal Kennedy St, 210-06/23 42nd Ave, and 210-01/05 43rd Ave -Parent's 50.6 kBtu/ft² across 208,345 sq ft works out to about 10.5 billion Btu (3,090 MWh-equivalent) in 2024. Its source EUI of 72.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 671,977 kWh of electricity, 82,517 therms of natural gas and 10,284 thousand gallons of water for the year.
