How does 256 W 36th 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. 256 W 36th St's ENERGY STAR score of 90 compares with an average of 72 across the 2,519 that report a score; it scores higher than 74% of them and lower than 23%. Its site EUI of 33.4 kBtu/ft² is about half of 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 3.1 kgCO₂e/ft² is about half of the group average of 5.8 kgCO₂e/ft².
At 35,000 sq ft, it is about 83% below the average floor area of 205,440 sq ft for those buildings. It was built in 1917, 23 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 90 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 90 means the building performs better than about 90% of its national peers. BuildingCensus bands the score into report-card grades; 90 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. 256 W 36th St's 33.4 kBtu/ft² across 35,000 sq ft works out to about 1.2 billion Btu (343 MWh-equivalent) in 2024. Its source EUI of 72.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 221,892 kWh of electricity and 4,106 therms of natural gas for the year.
