What does an ENERGY STAR score of 49 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 49 means the building performs better than about 49% of its national peers. BuildingCensus bands the score into report-card grades; 49 falls in band D — lowest band (1–54). It sits 26 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. 21551 Prairie Avenue's 14.5 kBtu/ft² across 57,665 sq ft works out to about 0.8 billion Btu (245 MWh-equivalent) in 2021. The disclosure also reports 249,740 kWh of electricity for the year.
