How has Casa La Paz's energy performance changed over time?
BuildingCensus holds 2 California disclosures for Casa La Paz, covering report years 2023–2024. Its ENERGY STAR score went from 69 in 2023 to 80 in 2024 (+11 points).

What does an ENERGY STAR score of 80 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 80 means the building performs better than about 80% of its national peers. BuildingCensus bands the score into report-card grades; 80 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 La Paz's 44.8 kBtu/ft² across 114,932 sq ft works out to about 5.1 billion Btu (1,509 MWh-equivalent) in 2024. The disclosure also reports 406,738 kWh of electricity and 36,597 therms of natural gas for the year.
Which law requires Casa La Paz to report its energy use?
