What does an ENERGY STAR score of 95 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 95 means the building performs better than about 95% of its national peers. BuildingCensus bands the score into report-card grades; 95 falls in band A — high performer (85–100). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. 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. (4578-4580) - 211 Brighton 15th Street/1511-1521 Brightwater Ave's 55.8 kBtu/ft² across 109,832 sq ft works out to about 6.1 billion Btu (1,796 MWh-equivalent) in 2023. Its source EUI of 78.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 368,813 kWh of electricity, 48,648 therms of natural gas and 6,586 thousand gallons of water for the year.
