Rocklyn: Transfiguration (3022070002)'s ENERGY STAR score of 95 compares with an average of 64 across the 2,052 that report a score; it scores higher than 91% of them and lower than 8%. Its site EUI of 13.8 kBtu/ft² is about 77% below the average of 61.3 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 1.5 kgCO₂e/ft² is about 69% below the group average of 4.8 kgCO₂e/ft².
At 47,615 sq ft, it is about half of the average floor area of 101,338 sq ft for those buildings. It was built in 1950, 3 years earlier than the group's average year built (1954).

What does an ENERGY STAR score of 95 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 95 means the building performs better than about 95% of its national peers. BuildingCensus bands the score into report-card grades; 95 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. Rocklyn: Transfiguration (3022070002)'s 13.8 kBtu/ft² across 47,615 sq ft works out to about 0.7 billion Btu (193 MWh-equivalent) in 2023. Its source EUI of 38.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 193,271 kWh of electricity and 247 thousand gallons of water for the year.
