How has X064, X924 (OECID: 0200100; BBL: 2028430040)'s energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for X064, X924 (OECID: 0200100; BBL: 2028430040), covering report years 2022–2024. Its ENERGY STAR score went from 75 in 2022 to 80 in 2024 (+5 points). Site EUI moved from 75.6 kBtu/ft² (2022) to 61.9 kBtu/ft² (2024), a 18% decrease. Reported emissions went from 562 tCO₂e to 522 tCO₂e over the same span (down 7%).
What does an ENERGY STAR score of 80 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 80 means the building performs better than about 80% of its national peers. BuildingCensus bands the score into report-card grades; 80 falls in band B — above median (70–84). 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. X064, X924 (OECID: 0200100; BBL: 2028430040)'s 61.9 kBtu/ft² across 96,700 sq ft works out to about 6 billion Btu (1,754 MWh-equivalent) in 2024. Its source EUI of 98.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 564,799 kWh of electricity, 2,459 therms of natural gas and 1,009 thousand gallons of water for the year.
Which law requires X064, X924 (OECID: 0200100; BBL: 2028430040) to report its energy use?
