What does an ENERGY STAR score of 6 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 6 means the building performs better than about 6% of its national peers. BuildingCensus bands the score into report-card grades; 6 falls in band D — lowest band (1–54). It sits 69 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. Union Lofts's 73.3 kBtu/ft² across 86,681 sq ft works out to about 6.4 billion Btu (1,862 MWh-equivalent) in 2024. The disclosure also reports 798,067 kWh of electricity for the year.
