How has M841 (OECID: 0100033; BBL: 1012300001)'s energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for M841 (OECID: 0100033; BBL: 1012300001), covering report years 2022–2024. Its ENERGY STAR score went from 67 in 2022 to 69 in 2024 (+2 points); its best year on file was 2023, at 79. Site EUI moved from 92.1 kBtu/ft² (2022) to 82.1 kBtu/ft² (2024), a 11% decrease. Reported emissions went from 468 tCO₂e to 490 tCO₂e over the same span (up 5%).
What does an ENERGY STAR score of 69 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 69 means the building performs better than about 69% of its national peers. BuildingCensus bands the score into report-card grades; 69 falls in band C — below median (55–69). It sits 6 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. M841 (OECID: 0100033; BBL: 1012300001)'s 82.1 kBtu/ft² across 64,880 sq ft works out to about 5.3 billion Btu (1,561 MWh-equivalent) in 2024. Its source EUI of 146.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 677,914 kWh of electricity, 844 therms of natural gas and 1,026 thousand gallons of water for the year.
