How does Flatiron Association compare with other office buildings in New York City?
The latest disclosures cover 3,384 office buildings in New York City, out of 48,310 buildings citywide. Flatiron Association's ENERGY STAR score of 89 compares with an average of 72 across the 2,519 that report a score; it scores higher than 72% of them and lower than 26%. Its site EUI of 46.5 kBtu/ft² is about 28% below the average of 64.5 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 3.6 kgCO₂e/ft² is about 38% below the group average of 5.8 kgCO₂e/ft².
At 193,000 sq ft, it is roughly in line with the average floor area of 205,440 sq ft for those buildings. It was built in 1902, 38 years earlier than the group's average year built (1940). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².
What does an ENERGY STAR score of 89 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 89 means the building performs better than about 89% of its national peers. BuildingCensus bands the score into report-card grades; 89 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. Flatiron Association's 46.5 kBtu/ft² across 193,000 sq ft works out to about 9 billion Btu (2,630 MWh-equivalent) in 2022. Its source EUI of 75.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 892,713 kWh of electricity and 945 thousand gallons of water for the year.
Which law requires Flatiron Association to report its energy use?
Flatiron Association 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 2022 disclosure (source record nyc:3134101:2022). 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.
