How has 301- 5 Seventh Ave Assoc.'s energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for 301- 5 Seventh Ave Assoc., covering report years 2022–2024. Its ENERGY STAR score was 90 in both 2022 and 2024.

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. 301- 5 Seventh Ave Assoc.'s 57.0 kBtu/ft² across 180,023 sq ft works out to about 10.3 billion Btu (3,007 MWh-equivalent) in 2024. Its source EUI of 110.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,570,015 kWh of electricity, 34 therms of natural gas and 1,906 thousand gallons of water for the year.
