How has Q520 (OECID: 0401069; BBL: 4002490001)'s energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for Q520 (OECID: 0401069; BBL: 4002490001), covering report years 2022–2024. Its ENERGY STAR score went from 35 in 2022 to 57 in 2024 (+22 points). Site EUI moved from 95.1 kBtu/ft² (2022) to 63.4 kBtu/ft² (2024), a 33% decrease. Reported emissions went from 494 tCO₂e to 476 tCO₂e over the same span (down 4%).
What does an ENERGY STAR score of 57 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 57 means the building performs better than about 57% of its national peers. BuildingCensus bands the score into report-card grades; 57 falls in band C — below median (55–69). It sits 18 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. Q520 (OECID: 0401069; BBL: 4002490001)'s 63.4 kBtu/ft² across 70,000 sq ft works out to about 4.4 billion Btu (1,301 MWh-equivalent) in 2024. Its source EUI of 163.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,133,879 kWh of electricity, 5,710 therms of natural gas and 637 thousand gallons of water for the year.
