Its site EUI of 50.8 kBtu/ft² is about 23% below the average of 65.6 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 3.0 kgCO₂e/ft² is about 25% below the group average of 4.0 kgCO₂e/ft².

At 60,246 sq ft, it is about 64% below the average floor area of 167,786 sq ft for those buildings. It was built in 1958, 30 years earlier than the group's average year built (1988).

What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 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. 9520 Castillo Dr - Ab802's 50.8 kBtu/ft² across 60,246 sq ft works out to about 3.1 billion Btu (897 MWh-equivalent) in 2024. The disclosure also reports 322,565 kWh of electricity and 20,166 therms of natural gas for the year.
