Its site EUI of 83.9 kBtu/ft² is about 30% 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 7.1 kgCO₂e/ft² is about 23% above the group average of 5.8 kgCO₂e/ft².
At 53,281 sq ft, it is about 74% below the average floor area of 205,440 sq ft for those buildings. It was built in 1925, 15 years earlier than the group's average year built (1940).

What does an ENERGY STAR score of 58 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 58 means the building performs better than about 58% of its national peers. BuildingCensus bands the score into report-card grades; 58 falls in band C — below median (55–69). It sits 17 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. 115 W 45th St's 83.9 kBtu/ft² across 53,281 sq ft works out to about 4.5 billion Btu (1,310 MWh-equivalent) in 2024. Its source EUI of 147.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 540,144 kWh of electricity, 12,814 therms of natural gas and 1,709 thousand gallons of water for the year.
