How has Cottonwood Creek's energy performance changed over time?
BuildingCensus holds 6 California disclosures for Cottonwood Creek, covering report years 2019–2024. Its ENERGY STAR score went from 94 in 2019 to 100 in 2024 (+6 points); its best year on file was 2022, at 100. Site EUI moved from 37.2 kBtu/ft² (2019) to 28.2 kBtu/ft² (2024), a 24% decrease.

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. Cottonwood Creek's 28.2 kBtu/ft² across 86,030 sq ft works out to about 2.4 billion Btu (711 MWh-equivalent) in 2024. The disclosure also reports 230,056 kWh of electricity and 16,572 therms of natural gas for the year.
Which law requires Cottonwood Creek to report its energy use?
