455 Jefferson

How does 455 Jefferson 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. 455 Jefferson's ENERGY STAR score of 62 compares with an average of 72 across the 2,519 that report a score; it scores higher than 26% of them and lower than 73%. Its site EUI of 58.0 kBtu/ft² is about 10% 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 6.7 kgCO₂e/ft² is about 15% above the group average of 5.8 kgCO₂e/ft².

At 105,289 sq ft, it is about half of the average floor area of 205,440 sq ft for those buildings. It was built in 1930, 10 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 62 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 62 means the building performs better than about 62% of its national peers. BuildingCensus bands the score into report-card grades; 62 falls in band C — below median (55–69). It sits 13 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. 455 Jefferson's 58.0 kBtu/ft² across 105,289 sq ft works out to about 6.1 billion Btu (1,790 MWh-equivalent) in 2024. Its source EUI of 162.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,789,841 kWh of electricity and 5,581 thousand gallons of water for the year.

Which law requires 455 Jefferson to report its energy use?

455 Jefferson 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:20835118:2024). 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.
