What does an ENERGY STAR score of 42 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 42 means the building performs better than about 42% of its national peers. BuildingCensus bands the score into report-card grades; 42 falls in band D — lowest band (1–54). It sits 33 points below 75, the threshold for ENERGY STAR certification. 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. Sand Hill Commons I/Ii (2)'s 101.5 kBtu/ft² across 133,124 sq ft works out to about 13.5 billion Btu (3,960 MWh-equivalent) in 2022. The disclosure also reports 2,038,939 kWh of electricity and 66,168 therms of natural gas for the year.
