How has K997 (OECID: 0301717; BBL: 3067390077)'s energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for K997 (OECID: 0301717; BBL: 3067390077), covering report years 2022–2024. Its ENERGY STAR score went from 76 in 2022 to 83 in 2024 (+7 points).

What does an ENERGY STAR score of 83 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 83 means the building performs better than about 83% of its national peers. BuildingCensus bands the score into report-card grades; 83 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. K997 (OECID: 0301717; BBL: 3067390077)'s 63.4 kBtu/ft² across 27,600 sq ft works out to about 1.7 billion Btu (513 MWh-equivalent) in 2024. Its source EUI of 164.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 452,951 kWh of electricity, 2,043 therms of natural gas and 0 thousand gallons of water for the year.
