What does an ENERGY STAR score of 56 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 56 means the building performs better than about 56% of its national peers. BuildingCensus bands the score into report-card grades; 56 falls in band C — below median (55–69). It sits 19 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. Harmony Creek's 47.6 kBtu/ft² across 61,750 sq ft works out to about 2.9 billion Btu (861 MWh-equivalent) in 2024. The disclosure also reports 323,255 kWh of electricity and 17,437 therms of natural gas for the year.
