How has UNICEF HOUSE's energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for UNICEF HOUSE, covering report years 2022–2024. Its ENERGY STAR score went from 86 in 2022 to 88 in 2024 (+2 points). Site EUI moved from 84.1 kBtu/ft² (2022) to 70.9 kBtu/ft² (2024), a 16% decrease. Reported emissions went from 1,356 tCO₂e to 1,553 tCO₂e over the same span (up 15%).
What does an ENERGY STAR score of 88 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 88 means the building performs better than about 88% of its national peers. BuildingCensus bands the score into report-card grades; 88 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. UNICEF HOUSE's 70.9 kBtu/ft² across 208,203 sq ft works out to about 14.8 billion Btu (4,326 MWh-equivalent) in 2024. Its source EUI of 175.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,450,592 kWh of electricity and 6,154 thousand gallons of water for the year.
Which law requires UNICEF HOUSE to report its energy use?
UNICEF HOUSE reports under Local Law 84 (LL84), the legal basis of New York City's Energy and Water Data Disclosure program, which publishes each covered building's annual benchmarking results.
