What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 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. 1 Lefrak City Plaza Office/Retail's 2.0 kBtu/ft² across 454,645 sq ft works out to about 0.9 billion Btu (266 MWh-equivalent) in 2022. Its source EUI of 2.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher.
