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. Dekalb Gardens's 33.5 kBtu/ft² across 66,000 sq ft works out to about 2.2 billion Btu (648 MWh-equivalent) in 2024. Its source EUI of 85.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 553,486 kWh of electricity, 3,211 therms of natural gas and 3,369 thousand gallons of water for the year.
