What does an ENERGY STAR score of 61 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 61 means the building performs better than about 61% of its national peers. BuildingCensus bands the score into report-card grades; 61 falls in band C — below median (55–69). It sits 14 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. 921-23 Barretto Street's 80.9 kBtu/ft² across 36,575 sq ft works out to about 3 billion Btu (867 MWh-equivalent) in 2024. Its source EUI of 102.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 107,786 kWh of electricity, 25,910 therms of natural gas and 2,008 thousand gallons of water for the year.
