How does 346 First Street Owners' Association compare with other multifamily housing buildings in California?

Its site EUI of 21.9 kBtu/ft² is about 36% 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 1.3 kgCO₂e/ft² is about 39% below the group average of 2.1 kgCO₂e/ft².
At 60,372 sq ft, it is about 60% below the average floor area of 150,919 sq ft for those buildings. It was built in 1996, 8 years later than the group's average year built (1988). Across all 24 jurisdictions BuildingCensus covers, the 59,945 multifamily housing buildings average an ENERGY STAR score of 70 and a site EUI of 59.0 kBtu/ft².
What does an ENERGY STAR score of 84 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 84 means the building performs better than about 84% of its national peers. BuildingCensus bands the score into report-card grades; 84 falls in band B — above median (70–84). 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. 346 First Street Owners' Association's 21.9 kBtu/ft² across 60,372 sq ft works out to about 1.3 billion Btu (387 MWh-equivalent) in 2019. The disclosure also reports 145,300 kWh of electricity and 8,003 therms of natural gas for the year.
Which law requires 346 First Street Owners' Association to report its energy use?
