Buckingham House's ENERGY STAR score of 35 compares with an average of 63 across the 22,829 that report a score; it scores higher than 20% of them and lower than 79%. Its site EUI of 115.6 kBtu/ft² is about 54% above the average of 74.9 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 8.0 kgCO₂e/ft² is about 54% above the group average of 5.2 kgCO₂e/ft².
At 13,830 sq ft, it is about 86% below the average floor area of 100,951 sq ft for those buildings. It was built in 1931, 21 years earlier than the group's average year built (1952).

What does an ENERGY STAR score of 35 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 35 means the building performs better than about 35% of its national peers. BuildingCensus bands the score into report-card grades; 35 falls in band D — lowest band (1–54). It sits 40 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. Buckingham House's 115.6 kBtu/ft² across 13,830 sq ft works out to about 1.6 billion Btu (469 MWh-equivalent) in 2023. Its source EUI of 181.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 138,369 kWh of electricity and 11,266 therms of natural gas for the year.
Which law requires Buckingham House to report its energy use?
