Chez 66's ENERGY STAR score of 38 compares with an average of 63 across the 22,829 that report a score; it scores higher than 22% of them and lower than 77%. Its site EUI of 72.2 kBtu/ft² is roughly in line with the average of 74.9 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 5.7 kgCO₂e/ft² is roughly in line with the group average of 5.2 kgCO₂e/ft².

At 50,074 sq ft, it is about half of the average floor area of 100,951 sq ft for those buildings. It was built in 1920, 32 years earlier than the group's average year built (1952). Across all 24 jurisdictions BuildingCensus covers, the 59,945 multifamily housing buildings average an ENERGY STAR score of 70 and a site EUI of 59.0 kBtu/ft².

How has Chez 66's energy performance changed over time?

BuildingCensus holds 2 New York City disclosures for Chez 66, covering report years 2022–2023. Its ENERGY STAR score went from 29 in 2022 to 38 in 2023 (+9 points). Site EUI moved from 82.4 kBtu/ft² (2022) to 72.2 kBtu/ft² (2023), a 12% decrease. Reported emissions went from 295 tCO₂e to 287 tCO₂e over the same span (down 3%).

What does an ENERGY STAR score of 38 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 38 means the building performs better than about 38% of its national peers. BuildingCensus bands the score into report-card grades; 38 falls in band D — lowest band (1–54). It sits 37 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. Chez 66's 72.2 kBtu/ft² across 50,074 sq ft works out to about 3.6 billion Btu (1,060 MWh-equivalent) in 2023. Its source EUI of 123.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 340,294 kWh of electricity, 2,042 therms of natural gas and 1,375 thousand gallons of water for the year.

Which law requires Chez 66 to report its energy use?

Chez 66 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 2023 disclosure (source record nyc:2604354:2023). 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.
