How has AKA United Nations's energy performance changed over time?
BuildingCensus holds 2 New York City disclosures for AKA United Nations, covering report years 2022–2023. Its ENERGY STAR score was 100 in both 2022 and 2023.

What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 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. AKA United Nations's 2.8 kBtu/ft² across 102,877 sq ft works out to about 0.3 billion Btu (84 MWh-equivalent) in 2023. Its source EUI of 7.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 83,073 kWh of electricity and 51 therms of natural gas for the year.
