How has M451 (OECID: 0101197; BBL: 1007670068)'s energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for M451 (OECID: 0101197; BBL: 1007670068), covering report years 2022–2024. Its ENERGY STAR score went from 41 in 2022 to 63 in 2024 (+22 points). Site EUI moved from 54.8 kBtu/ft² (2022) to 38.3 kBtu/ft² (2024), a 30% decrease. Reported emissions went from 220 tCO₂e to 208 tCO₂e over the same span (down 5%).
What does an ENERGY STAR score of 63 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 63 means the building performs better than about 63% of its national peers. BuildingCensus bands the score into report-card grades; 63 falls in band C — below median (55–69). It sits 12 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. M451 (OECID: 0101197; BBL: 1007670068)'s 38.3 kBtu/ft² across 48,953 sq ft works out to about 1.9 billion Btu (549 MWh-equivalent) in 2024. Its source EUI of 102.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 513,537 kWh of electricity, 1,217 therms of natural gas and 702 thousand gallons of water for the year.
