What does an ENERGY STAR score of 80 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 80 means the building performs better than about 80% of its national peers. BuildingCensus bands the score into report-card grades; 80 falls in band B — above median (70–84). 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 California, 65% 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. 919 East Hillsdale's 46.5 kBtu/ft² across 142,667 sq ft works out to about 6.6 billion Btu (1,944 MWh-equivalent) in 2024. The disclosure also reports 1,848,918 kWh of electricity and 2,742 therms of natural gas for the year.
