How has Mission Ridge 27101's energy performance changed over time?
BuildingCensus holds 3 California disclosures for Mission Ridge 27101, covering report years 2022–2024. Its ENERGY STAR score went from 92 in 2022 to 93 in 2024 (+1 points).

What does an ENERGY STAR score of 93 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 93 means the building performs better than about 93% of its national peers. BuildingCensus bands the score into report-card grades; 93 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. Mission Ridge 27101's 27.2 kBtu/ft² across 120,322 sq ft works out to about 3.3 billion Btu (959 MWh-equivalent) in 2024. The disclosure also reports 808,004 kWh of electricity and 5,416 therms of natural gas for the year.
