What does an ENERGY STAR score of 96 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 96 means the building performs better than about 96% of its national peers. BuildingCensus bands the score into report-card grades; 96 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 San Francisco, 73% 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. Hawthorne Plaza - 75 Hawthorne's 35.5 kBtu/ft² across 408,667 sq ft works out to about 14.5 billion Btu (4,252 MWh-equivalent) in 2025. Its source EUI of 78.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,437,445 kWh of electricity and 43,689 therms of natural gas for the year.
Which law requires Hawthorne Plaza - 75 Hawthorne to report its energy use?
