Its site EUI of 36.2 kBtu/ft² is about 44% below the average of 64.5 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 2.6 kgCO₂e/ft² is about 55% below the group average of 5.8 kgCO₂e/ft².
At 63,932 sq ft, it is about 69% below the average floor area of 205,440 sq ft for those buildings. It was built in 1873, 67 years earlier than the group's average year built (1940). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².
What does an ENERGY STAR score of 91 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 91 means the building performs better than about 91% of its national peers. BuildingCensus bands the score into report-card grades; 91 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. 670 Broadway's 36.2 kBtu/ft² across 63,932 sq ft works out to about 2.3 billion Btu (678 MWh-equivalent) in 2022. Its source EUI of 78.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 432,947 kWh of electricity and 1,926 thousand gallons of water for the year.
