Q490, Q491 (OECID: 0400216; BBL: 4110490001)

How does Q490, Q491 (OECID: 0400216; BBL: 4110490001) compare with other K-12 school buildings in New York City?

The latest disclosures cover 2,301 K-12 school buildings in New York City, out of 48,310 buildings citywide. Q490, Q491 (OECID: 0400216; BBL: 4110490001)'s ENERGY STAR score of 79 compares with an average of 64 across the 2,052 that report a score; it scores higher than 64% of them and lower than 34%. Its site EUI of 66.4 kBtu/ft² is roughly in line with the average of 61.3 kBtu/ft². Its emissions intensity of 4.1 kgCO₂e/ft² is about 15% below the group average of 4.8 kgCO₂e/ft².

At 312,200 sq ft, it is about 208% above the average floor area of 101,338 sq ft for those buildings. It was built in 1939, 14 years earlier than the group's average year built (1954). Across all 24 jurisdictions BuildingCensus covers, the 6,548 K-12 school buildings average an ENERGY STAR score of 64 and a site EUI of 52.7 kBtu/ft².

How has Q490, Q491 (OECID: 0400216; BBL: 4110490001)'s energy performance changed over time?

BuildingCensus holds 3 New York City disclosures for Q490, Q491 (OECID: 0400216; BBL: 4110490001), covering report years 2022–2024. Its ENERGY STAR score went from 60 in 2022 to 79 in 2024 (+19 points). Site EUI moved from 87.8 kBtu/ft² (2022) to 66.4 kBtu/ft² (2024), a 24% decrease. Reported emissions went from 1,557 tCO₂e to 1,267 tCO₂e over the same span (down 19%).

What does an ENERGY STAR score of 79 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 79 means the building performs better than about 79% of its national peers. BuildingCensus bands the score into report-card grades; 79 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. Q490, Q491 (OECID: 0400216; BBL: 4110490001)'s 66.4 kBtu/ft² across 312,200 sq ft works out to about 20.7 billion Btu (6,075 MWh-equivalent) in 2024. Its source EUI of 89.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,033,653 kWh of electricity, 153,356 therms of natural gas and 1,269 thousand gallons of water for the year.

Which law requires Q490, Q491 (OECID: 0400216; BBL: 4110490001) to report its energy use?

Q490, Q491 (OECID: 0400216; BBL: 4110490001) 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. The record shown here is the report-year 2024 disclosure (source record nyc:1634550:2024). Under Local Law 97, buildings over 25,000 sq ft face carbon caps with fines of $268 per metric ton of CO₂e over the limit, phasing in from 2024.
