Bay Inn Apartments's ENERGY STAR score of 99 compares with an average of 82 across the 9,612 that report a score; it scores higher than 71% of them and lower than 24%. Its site EUI of 26.8 kBtu/ft² is about 22% below the average of 34.4 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 1.5 kgCO₂e/ft² is about 29% below the group average of 2.1 kgCO₂e/ft².
At 51,510 sq ft, it is about 66% below the average floor area of 150,919 sq ft for those buildings. It was built in 1962, 26 years earlier than the group's average year built (1988).

What does an ENERGY STAR score of 99 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 99 means the building performs better than about 99% of its national peers. BuildingCensus bands the score into report-card grades; 99 falls in band A — high performer (85–100). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. 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. Bay Inn Apartments's 26.8 kBtu/ft² across 51,510 sq ft works out to about 1.4 billion Btu (405 MWh-equivalent) in 2021. The disclosure also reports 146,656 kWh of electricity and 8,926 therms of natural gas for the year.
Which law requires Bay Inn Apartments to report its energy use?
