What does an ENERGY STAR score of 16 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 16 means the building performs better than about 16% of its national peers. BuildingCensus bands the score into report-card grades; 16 falls in band D — lowest band (1–54). It sits 59 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. Piazza D' Oro (Pz01)'s 31.5 kBtu/ft² across 371,027 sq ft works out to about 11.7 billion Btu (3,425 MWh-equivalent) in 2024. The disclosure also reports 1,525,896 kWh of electricity and 67,836 therms of natural gas for the year.
