How has Rio Vista Tower Iii's energy performance changed over time?
BuildingCensus holds 2 California disclosures for Rio Vista Tower Iii, covering report years 2018–2019. Its ENERGY STAR score went from 86 in 2018 to 84 in 2019 (-2 points); its best year on file was 2018, at 86. Site EUI moved from 36.0 kBtu/ft² (2018) to 39.7 kBtu/ft² (2019), an 10% increase. Reported emissions went from 205 tCO₂e to 223 tCO₂e over the same span (up 9%).
What does an ENERGY STAR score of 84 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 84 means the building performs better than about 84% of its national peers. BuildingCensus bands the score into report-card grades; 84 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. Rio Vista Tower Iii's 39.7 kBtu/ft² across 81,799 sq ft works out to about 3.2 billion Btu (952 MWh-equivalent) in 2019. The disclosure also reports 848,311 kWh of electricity and 3,639 therms of natural gas for the year.
