How has Q239 (OECID: 0401471; BBL: 4035610001)'s energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for Q239 (OECID: 0401471; BBL: 4035610001), covering report years 2022–2024. Its ENERGY STAR score went from 17 in 2022 to 33 in 2024 (+16 points). Site EUI moved from 83.5 kBtu/ft² (2022) to 64.6 kBtu/ft² (2024), a 23% decrease. Reported emissions went from 687 tCO₂e to 669 tCO₂e over the same span (down 3%).
What does an ENERGY STAR score of 33 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 33 means the building performs better than about 33% of its national peers. BuildingCensus bands the score into report-card grades; 33 falls in band D — lowest band (1–54). It sits 42 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. Q239 (OECID: 0401471; BBL: 4035610001)'s 64.6 kBtu/ft² across 117,126 sq ft works out to about 7.6 billion Btu (2,217 MWh-equivalent) in 2024. Its source EUI of 126.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,163,622 kWh of electricity, 25,711 therms of natural gas and 781 thousand gallons of water for the year.
