How has Vista Hermosa Apartments's energy performance changed over time?
BuildingCensus holds 6 California disclosures for Vista Hermosa Apartments, covering report years 2019–2024. Its ENERGY STAR score was 100 in both 2020 and 2024.

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. Vista Hermosa Apartments's 8.9 kBtu/ft² across 54,672 sq ft works out to about 0.5 billion Btu (143 MWh-equivalent) in 2024. The disclosure also reports 57,782 kWh of electricity and 3,114 therms of natural gas for the year.
