How has 901 Liberty Station's energy performance changed over time?
BuildingCensus holds 2 San Diego disclosures for 901 Liberty Station, covering report years 2021–2022. Its ENERGY STAR score went from 85 in 2021 to 83 in 2022 (-2 points); its best year on file was 2021, at 85. Site EUI moved from 30.2 kBtu/ft² (2021) to 30.0 kBtu/ft² (2022), a 1% decrease.
What does an ENERGY STAR score of 83 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 83 means the building performs better than about 83% of its national peers. BuildingCensus bands the score into report-card grades; 83 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 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. 901 Liberty Station's 30.0 kBtu/ft² across 50,568 sq ft works out to about 1.5 billion Btu (445 MWh-equivalent) in 2022.
Which law requires 901 Liberty Station to report its energy use?
