Its ENERGY STAR score went from 22 in 2019 to 97 in 2024 (+75 points); its best year on file was 2021, at 100. Site EUI moved from 68.5 kBtu/ft² (2019) to 33.6 kBtu/ft² (2024), a 51% decrease.

What does an ENERGY STAR score of 97 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 97 means the building performs better than about 97% of its national peers. BuildingCensus bands the score into report-card grades; 97 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. River Oaks (Rv56;Rivoaks2)'s 33.6 kBtu/ft² across 309,552 sq ft works out to about 10.4 billion Btu (3,048 MWh-equivalent) in 2024. The disclosure also reports 897,787 kWh of electricity and 73,705 therms of natural gas for the year.
