How has Dumont Green's energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for Dumont Green, covering report years 2022–2024. Its ENERGY STAR score went from 64 in 2022 to 68 in 2024 (+4 points).

What does an ENERGY STAR score of 68 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 68 means the building performs better than about 68% of its national peers. BuildingCensus bands the score into report-card grades; 68 falls in band C — below median (55–69). It sits 7 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. Dumont Green's 69.4 kBtu/ft² across 172,000 sq ft works out to about 11.9 billion Btu (3,498 MWh-equivalent) in 2024. Its source EUI of 105.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 935,811 kWh of electricity, 87,419 therms of natural gas and 9,426 thousand gallons of water for the year.
