What does an ENERGY STAR score of 84 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 84 means the building performs better than about 84% of its national peers. BuildingCensus bands the score into report-card grades; 84 falls in band B — above median (70–84). 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. 77 West 15th Street's 52.9 kBtu/ft² across 91,875 sq ft works out to about 4.9 billion Btu (1,424 MWh-equivalent) in 2023. Its source EUI of 91.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 549,049 kWh of electricity, 29,894 therms of natural gas and 3,831 thousand gallons of water for the year.
