Uptown Villa Apartments's ENERGY STAR score of 100 compares with an average of 82 across the 9,612 that report a score; it scores higher than 76% of them. Its site EUI of 21.3 kBtu/ft² is about 38% 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 1.2 kgCO₂e/ft² is about 43% below the group average of 2.1 kgCO₂e/ft².
At 55,750 sq ft, it is about 63% below the average floor area of 150,919 sq ft for those buildings. Its 1989 construction date is close to 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. Uptown Villa Apartments's 21.3 kBtu/ft² across 55,750 sq ft works out to about 1.2 billion Btu (348 MWh-equivalent) in 2019. The disclosure also reports 61,532 kWh of electricity and 9,681 therms of natural gas for the year.
