What does an ENERGY STAR score of 67 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 67 means the building performs better than about 67% of its national peers. BuildingCensus bands the score into report-card grades; 67 falls in band C — below median (55–69). It sits 8 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. 305 Rider Ave's 71.2 kBtu/ft² across 75,500 sq ft works out to about 5.4 billion Btu (1,575 MWh-equivalent) in 2024. Its source EUI of 154.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,018,025 kWh of electricity, 1,928 therms of natural gas and 879 thousand gallons of water for the year.
