What does an ENERGY STAR score of 85 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 85 means the building performs better than about 85% of its national peers. BuildingCensus bands the score into report-card grades; 85 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. Sunset Park Library & Apartments's 45.5 kBtu/ft² across 71,636 sq ft works out to about 3.3 billion Btu (955 MWh-equivalent) in 2024. Its source EUI of 86.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 462,991 kWh of electricity and 16,815 therms of natural gas for the year.
