What does an ENERGY STAR score of 27 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 27 means the building performs better than about 27% of its national peers. BuildingCensus bands the score into report-card grades; 27 falls in band D — lowest band (1–54). It sits 48 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. 3505 Rochambeau Ave's 124.3 kBtu/ft² across 35,400 sq ft works out to about 4.4 billion Btu (1,290 MWh-equivalent) in 2023. Its source EUI of 193.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 374,590 kWh of electricity and 31,216 therms of natural gas for the year.
