How has K157 (OECID: 0300159; BBL: 3018970013)'s energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for K157 (OECID: 0300159; BBL: 3018970013), covering report years 2022–2024. Its ENERGY STAR score went from 41 in 2022 to 67 in 2024 (+26 points). Site EUI moved from 79.9 kBtu/ft² (2022) to 54.0 kBtu/ft² (2024), a 32% decrease. Reported emissions went from 618 tCO₂e to 529 tCO₂e over the same span (down 14%).
What does an ENERGY STAR score of 67 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 67 means the building performs better than about 67% of its national peers. BuildingCensus bands the score into report-card grades; 67 falls in band C — below median (55–69). It sits 8 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. K157 (OECID: 0300159; BBL: 3018970013)'s 54.0 kBtu/ft² across 122,400 sq ft works out to about 6.6 billion Btu (1,937 MWh-equivalent) in 2024. Its source EUI of 77.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 442,913 kWh of electricity, 10,907 therms of natural gas and 1,216 thousand gallons of water for the year.
Which law requires K157 (OECID: 0300159; BBL: 3018970013) to report its energy use?
