How does 3870 Murphy Canyon Road compare with other office buildings in California?

Its site EUI of 29.9 kBtu/ft² is about half of the average of 56.4 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 2.0 kgCO₂e/ft² is about 43% below the group average of 3.6 kgCO₂e/ft².
At 55,018 sq ft, it is about 64% below the average floor area of 151,937 sq ft for those buildings. It was built in 1988, 3 years later than the group's average year built (1985). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².
What does an ENERGY STAR score of 88 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 88 means the building performs better than about 88% of its national peers. BuildingCensus bands the score into report-card grades; 88 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. 3870 Murphy Canyon Road's 29.9 kBtu/ft² across 55,018 sq ft works out to about 1.6 billion Btu (482 MWh-equivalent) in 2018. The disclosure also reports 440,760 kWh of electricity and 1,232 therms of natural gas for the year.
Which law requires 3870 Murphy Canyon Road to report its energy use?
