What does an ENERGY STAR score of 71 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 71 means the building performs better than about 71% of its national peers. BuildingCensus bands the score into report-card grades; 71 falls in band B — above median (70–84). It sits 4 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. RJJ Girls School's 46.2 kBtu/ft² across 63,400 sq ft works out to about 2.9 billion Btu (858 MWh-equivalent) in 2023. Its source EUI of 75.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 288,000 kWh of electricity, 19,486 therms of natural gas and 1,928 thousand gallons of water for the year.
