How has Q809 (OECID: 0401091; BBL: 4061850001)'s energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for Q809 (OECID: 0401091; BBL: 4061850001), covering report years 2022–2024. Its ENERGY STAR score went from 70 in 2022 to 41 in 2024 (-29 points); its best year on file was 2022, at 70. Site EUI moved from 69.4 kBtu/ft² (2022) to 92.7 kBtu/ft² (2024), an 34% increase. Reported emissions went from 98 tCO₂e to 141 tCO₂e over the same span (up 45%).
What does an ENERGY STAR score of 41 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 41 means the building performs better than about 41% of its national peers. BuildingCensus bands the score into report-card grades; 41 falls in band D — lowest band (1–54). It sits 34 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. Q809 (OECID: 0401091; BBL: 4061850001)'s 92.7 kBtu/ft² across 23,060 sq ft works out to about 2.1 billion Btu (626 MWh-equivalent) in 2024. Its source EUI of 131.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 130,769 kWh of electricity, 16,926 therms of natural gas and 294 thousand gallons of water for the year.
