What does an ENERGY STAR score of 74 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 74 means the building performs better than about 74% of its national peers. BuildingCensus bands the score into report-card grades; 74 falls in band B — above median (70–84). It sits 1 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. M125 (OECID: 0100114; BBL: 1019640012)'s 81.3 kBtu/ft² across 160,925 sq ft works out to about 13.1 billion Btu (3,834 MWh-equivalent) in 2024. Its source EUI of 121.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,045,097 kWh of electricity, 1 therms of natural gas and 0 thousand gallons of water for the year.
