How has K307 (OECID: 0300302; BBL: 3000560007)'s energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for K307 (OECID: 0300302; BBL: 3000560007), covering report years 2022–2024. Its ENERGY STAR score was 87 in both 2022 and 2024. Site EUI moved from 56.4 kBtu/ft² (2022) to 51.5 kBtu/ft² (2024), a 9% decrease. Reported emissions went from 483 tCO₂e to 472 tCO₂e over the same span (down 2%).
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. K307 (OECID: 0300302; BBL: 3000560007)'s 51.5 kBtu/ft² across 111,600 sq ft works out to about 5.7 billion Btu (1,684 MWh-equivalent) in 2024. Its source EUI of 72.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 369,953 kWh of electricity, 862 therms of natural gas and 0 thousand gallons of water for the year.
