How has Rio San Diego Plaza II's energy performance changed over time?
BuildingCensus holds 2 San Diego disclosures for Rio San Diego Plaza II, covering report years 2021–2022. Its ENERGY STAR score went from 67 in 2021 to 96 in 2022 (+29 points). Site EUI moved from 45.6 kBtu/ft² (2021) to 29.1 kBtu/ft² (2022), a 36% decrease.
What does an ENERGY STAR score of 96 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 96 means the building performs better than about 96% of its national peers. BuildingCensus bands the score into report-card grades; 96 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 San Diego, 73% 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. Rio San Diego Plaza II's 29.1 kBtu/ft² across 79,947 sq ft works out to about 2.3 billion Btu (682 MWh-equivalent) in 2022.
