How has Stonegate (St948)'s energy performance changed over time?
BuildingCensus holds 3 California disclosures for Stonegate (St948), covering report years 2021–2023. Its ENERGY STAR score was 94 in both 2022 and 2023.

What does an ENERGY STAR score of 94 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 94 means the building performs better than about 94% of its national peers. BuildingCensus bands the score into report-card grades; 94 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. Stonegate (St948)'s 37.9 kBtu/ft² across 285,536 sq ft works out to about 10.8 billion Btu (3,172 MWh-equivalent) in 2023. The disclosure also reports 1,499,176 kWh of electricity and 56,892 therms of natural gas for the year.
