How does Kiamie 256 LLC 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. Kiamie 256 LLC's ENERGY STAR score of 87 compares with an average of 72 across the 2,519 that report a score; it scores higher than 67% of them and lower than 30%. Its site EUI of 32.7 kBtu/ft² is about half of 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 2.4 kgCO₂e/ft² is about 59% below the group average of 5.8 kgCO₂e/ft².
At 36,000 sq ft, it is about 82% below the average floor area of 205,440 sq ft for those buildings. It was built in 2007, 67 years later 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 87 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 87 means the building performs better than about 87% of its national peers. BuildingCensus bands the score into report-card grades; 87 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. Kiamie 256 LLC's 32.7 kBtu/ft² across 36,000 sq ft works out to about 1.2 billion Btu (345 MWh-equivalent) in 2022. Its source EUI of 69.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 213,804 kWh of electricity for the year.
Which law requires Kiamie 256 LLC to report its energy use?
Kiamie 256 LLC 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:3523055:2022).
