Its site EUI of 27.9 kBtu/ft² is about 19% 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 1.8 kgCO₂e/ft² is about 14% below the group average of 2.1 kgCO₂e/ft².
At 62,550 sq ft, it is about 59% below the average floor area of 150,919 sq ft for those buildings. It was built in 1974, 14 years earlier than the group's average year built (1988).

What does an ENERGY STAR score of 78 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 78 means the building performs better than about 78% of its national peers. BuildingCensus bands the score into report-card grades; 78 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. Casa Serrano-Gk Mgt's 27.9 kBtu/ft² across 62,550 sq ft works out to about 1.7 billion Btu (511 MWh-equivalent) in 2019. The disclosure also reports 277,316 kWh of electricity and 8,185 therms of natural gas for the year.
Which law requires Casa Serrano-Gk Mgt to report its energy use?
