Birch Wathen Lenox School's ENERGY STAR score of 68 compares with an average of 64 across the 2,052 that report a score; it scores higher than 47% of them and lower than 51%. Its site EUI of 86.0 kBtu/ft² is about 40% above the average of 61.3 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 8.0 kgCO₂e/ft² is about 67% above the group average of 4.8 kgCO₂e/ft².

At 38,784 sq ft, it is about 62% below the average floor area of 101,338 sq ft for those buildings. It was built in 1927, 26 years earlier than the group's average year built (1954). Across all 24 jurisdictions BuildingCensus covers, the 6,548 K-12 school buildings average an ENERGY STAR score of 64 and a site EUI of 52.7 kBtu/ft².

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. Birch Wathen Lenox School's 86.0 kBtu/ft² across 38,784 sq ft works out to about 3.3 billion Btu (978 MWh-equivalent) in 2023. Its source EUI of 172.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 540,598 kWh of electricity, 814 therms of natural gas and 1,666 thousand gallons of water for the year.

Which law requires Birch Wathen Lenox School to report its energy use?
