How does 230 W 39th St compare with other office buildings in New York City?
The latest disclosures cover 3,384 office buildings in New York City, out of 48,310 buildings citywide. 230 W 39th St's ENERGY STAR score of 79 compares with an average of 72 across the 2,519 that report a score; it scores higher than 50% of them and lower than 48%. Its site EUI of 74.9 kBtu/ft² is about 16% above the average of 64.5 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 5.7 kgCO₂e/ft² is roughly in line with the group average of 5.8 kgCO₂e/ft².
At 59,488 sq ft, it is about 71% below the average floor area of 205,440 sq ft for those buildings. It was built in 1926, 14 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 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. 230 W 39th St's 74.9 kBtu/ft² across 59,488 sq ft works out to about 4.5 billion Btu (1,306 MWh-equivalent) in 2022. Its source EUI of 107.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 310,708 kWh of electricity and 2,309 thousand gallons of water for the year.
