How has K158 (OECID: 0300160; BBL: 3040150001)'s energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for K158 (OECID: 0300160; BBL: 3040150001), covering report years 2022–2024. Its ENERGY STAR score went from 49 in 2022 to 56 in 2024 (+7 points); its best year on file was 2023, at 56. Site EUI moved from 63.5 kBtu/ft² (2022) to 56.3 kBtu/ft² (2024), a 11% decrease. Reported emissions went from 416 tCO₂e to 402 tCO₂e over the same span (down 3%).
What does an ENERGY STAR score of 56 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 56 means the building performs better than about 56% of its national peers. BuildingCensus bands the score into report-card grades; 56 falls in band C — below median (55–69). It sits 19 points below 75, the threshold for ENERGY STAR certification. 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. K158 (OECID: 0300160; BBL: 3040150001)'s 56.3 kBtu/ft² across 102,000 sq ft works out to about 5.7 billion Btu (1,683 MWh-equivalent) in 2024. Its source EUI of 81.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 385,994 kWh of electricity, 37,083 therms of natural gas and 0 thousand gallons of water for the year.
