What does an ENERGY STAR score of 2 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 2 means the building performs better than about 2% of its national peers. BuildingCensus bands the score into report-card grades; 2 falls in band D — lowest band (1–54). It sits 73 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. 631 Foster Avenue's 151.8 kBtu/ft² across 51,240 sq ft works out to about 7.8 billion Btu (2,280 MWh-equivalent) in 2024. Its source EUI of 244.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 730,387 kWh of electricity, 52,884 therms of natural gas and 4,686 thousand gallons of water for the year.
