How has Omni San Diego's energy performance changed over time?
BuildingCensus holds 5 California disclosures for Omni San Diego, covering report years 2019, 2020, 2021, 2022, 2024. Its ENERGY STAR score went from 73 in 2019 to 79 in 2024 (+6 points); its best year on file was 2020, at 98. Site EUI moved from 89.8 kBtu/ft² (2019) to 87.6 kBtu/ft² (2024), a 2% decrease.
What does an ENERGY STAR score of 79 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 79 means the building performs better than about 79% of its national peers. BuildingCensus bands the score into report-card grades; 79 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. Omni San Diego's 87.6 kBtu/ft² across 600,728 sq ft works out to about 52.6 billion Btu (15,423 MWh-equivalent) in 2024. The disclosure also reports 3,491,677 kWh of electricity for the year.
Which law requires Omni San Diego to report its energy use?
