What does an ENERGY STAR score of 62 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 62 means the building performs better than about 62% of its national peers. BuildingCensus bands the score into report-card grades; 62 falls in band C — below median (55–69). It sits 13 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. Carlsbad W1's 54.2 kBtu/ft² across 60,000 sq ft works out to about 3.3 billion Btu (953 MWh-equivalent) in 2024. The disclosure also reports 728,030 kWh of electricity and 8,197 therms of natural gas for the year.
