Its ENERGY STAR score went from 70 in 2018 to 92 in 2024 (+22 points); its best year on file was 2021, at 100. Site EUI moved from 59.8 kBtu/ft² (2018) to 27.4 kBtu/ft² (2024), a 54% decrease.

What does an ENERGY STAR score of 92 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 92 means the building performs better than about 92% of its national peers. BuildingCensus bands the score into report-card grades; 92 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. Rio San Diego Plaza Ii's 27.4 kBtu/ft² across 79,947 sq ft works out to about 2.2 billion Btu (642 MWh-equivalent) in 2024. The disclosure also reports 593,509 kWh of electricity for the year.
Which law requires Rio San Diego Plaza Ii to report its energy use?
