Reported emissions went from 298 tCO₂e to 345 tCO₂e over the same span (up 16%).
What does an ENERGY STAR score of 64 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 64 means the building performs better than about 64% of its national peers. BuildingCensus bands the score into report-card grades; 64 falls in band C — below median (55–69). It sits 11 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. M661 (OECID: 0100185; BBL: 1009210064)'s 73.1 kBtu/ft² across 55,260 sq ft works out to about 4 billion Btu (1,184 MWh-equivalent) in 2024. Its source EUI of 134.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 480,789 kWh of electricity, 2,512 therms of natural gas and 0 thousand gallons of water for the year.
