How has Harlem Academy's energy performance changed over time?
BuildingCensus holds 2 New York City disclosures for Harlem Academy, covering report years 2023–2024. Site EUI moved from 63.1 kBtu/ft² (2023) to 62.6 kBtu/ft² (2024), a 1% decrease. Reported emissions went from 138 tCO₂e to 144 tCO₂e over the same span (up 4%).
What does an ENERGY STAR score of 54 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 54 means the building performs better than about 54% of its national peers. BuildingCensus bands the score into report-card grades; 54 falls in band D — lowest band (1–54). It sits 21 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. Harlem Academy's 62.6 kBtu/ft² across 27,877 sq ft works out to about 1.7 billion Btu (511 MWh-equivalent) in 2024. Its source EUI of 117.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 241,050 kWh of electricity, 9,222 therms of natural gas and 203 thousand gallons of water for the year.
