What does an ENERGY STAR score of 18 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 18 means the building performs better than about 18% of its national peers. BuildingCensus bands the score into report-card grades; 18 falls in band D — lowest band (1–54). It sits 57 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. GLENWOOD's 121.3 kBtu/ft² across 1,197,700 sq ft works out to about 145.3 billion Btu (42,578 MWh-equivalent) in 2024. Its source EUI of 160.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 6,697,753 kWh of electricity and 1,224,224 therms of natural gas for the year.
