Its site EUI of 66.4 kBtu/ft² is about 40% below the average of 111.4 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 5.9 kgCO₂e/ft² is about 32% below the group average of 8.7 kgCO₂e/ft².

At 46,500 sq ft, it is about 79% below the average floor area of 223,266 sq ft for those buildings. It was built in 2006, 43 years later than the group's average year built (1963). Across all 24 jurisdictions BuildingCensus covers, the 1,327 other buildings average an ENERGY STAR score of 60 and a site EUI of 63.3 kBtu/ft².

What does an ENERGY STAR score of 79 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 79 means the building performs better than about 79% of its national peers. BuildingCensus bands the score into report-card grades; 79 falls in band B — above median (70–84). 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. 317 DAHILL RD.'s 66.4 kBtu/ft² across 46,500 sq ft works out to about 3.1 billion Btu (905 MWh-equivalent) in 2024. Its source EUI of 137.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 525,692 kWh of electricity, 12,917 therms of natural gas and 3,566 thousand gallons of water for the year.
