How has M488 (OECID: 0101702; BBL: 1013300013)'s energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for M488 (OECID: 0101702; BBL: 1013300013), covering report years 2022–2024. Its ENERGY STAR score was 31 in both 2022 and 2024. Site EUI moved from 78.0 kBtu/ft² (2022) to 72.4 kBtu/ft² (2024), a 7% decrease. Reported emissions went from 1,766 tCO₂e to 2,148 tCO₂e over the same span (up 22%).
What does an ENERGY STAR score of 31 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 31 means the building performs better than about 31% of its national peers. BuildingCensus bands the score into report-card grades; 31 falls in band D — lowest band (1–54). It sits 44 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. M488 (OECID: 0101702; BBL: 1013300013)'s 72.4 kBtu/ft² across 304,477 sq ft works out to about 22 billion Btu (6,461 MWh-equivalent) in 2024. Its source EUI of 166.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 4,622,574 kWh of electricity and 62,687 therms of natural gas for the year.
