NB:377 Broadway's ENERGY STAR score of 73 compares with an average of 72 across the 2,519 that report a score; it scores higher than 39% of them and lower than 59%. Its site EUI of 47.8 kBtu/ft² is about 26% 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 5.4 kgCO₂e/ft² is roughly in line with the group average of 5.8 kgCO₂e/ft².
At 100,650 sq ft, it is about half of the average floor area of 205,440 sq ft for those buildings. It was built in 1920, 20 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 73 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 73 means the building performs better than about 73% of its national peers. BuildingCensus bands the score into report-card grades; 73 falls in band B — above median (70–84). It sits 2 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. NB:377 Broadway's 47.8 kBtu/ft² across 100,650 sq ft works out to about 4.8 billion Btu (1,410 MWh-equivalent) in 2024. Its source EUI of 132.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,379,288 kWh of electricity and 1,089 therms of natural gas for the year.
