Its site EUI of 10.9 kBtu/ft² is about 72% below the average of 39.3 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.7 kgCO₂e/ft² is about 77% below the group average of 3.1 kgCO₂e/ft².

At 72,100 sq ft, it is about 13% below the average floor area of 83,240 sq ft for those buildings. It was built in 1926, 27 years earlier than the group's average year built (1953). Across all 24 jurisdictions BuildingCensus covers, the 4,723 non-refrigerated warehouse buildings average an ENERGY STAR score of 66 and a site EUI of 26.0 kBtu/ft².

What does an ENERGY STAR score of 92 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 92 means the building performs better than about 92% of its national peers. BuildingCensus bands the score into report-card grades; 92 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. 495 Walton Avenue's 10.9 kBtu/ft² across 72,100 sq ft works out to about 0.8 billion Btu (230 MWh-equivalent) in 2022. Its source EUI of 17.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 74,806 kWh of electricity and 28 thousand gallons of water for the year.

Which law requires 495 Walton Avenue to report its energy use?
