How has K834, K764 (OECID: 0301751; BBL: 3004550001)'s energy performance changed over time?
BuildingCensus holds 2 New York City disclosures for K834, K764 (OECID: 0301751; BBL: 3004550001), covering report years 2022–2023. Its ENERGY STAR score went from 83 in 2022 to 89 in 2023 (+6 points). Site EUI moved from 73.3 kBtu/ft² (2022) to 55.7 kBtu/ft² (2023), a 24% decrease. Reported emissions went from 288 tCO₂e to 245 tCO₂e over the same span (down 15%).
What does an ENERGY STAR score of 89 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 89 means the building performs better than about 89% of its national peers. BuildingCensus bands the score into report-card grades; 89 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. K834, K764 (OECID: 0301751; BBL: 3004550001)'s 55.7 kBtu/ft² across 51,830 sq ft works out to about 2.9 billion Btu (846 MWh-equivalent) in 2023. Its source EUI of 89.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 282,000 kWh of electricity, 1,371 therms of natural gas and 195 thousand gallons of water for the year.
Which law requires K834, K764 (OECID: 0301751; BBL: 3004550001) to report its energy use?
