How has Nobel Executive Center's energy performance changed over time?
BuildingCensus holds 2 San Diego disclosures for Nobel Executive Center, covering report years 2021–2022. Its ENERGY STAR score went from 75 in 2021 to 65 in 2022 (-10 points); its best year on file was 2021, at 75. Site EUI moved from 66.9 kBtu/ft² (2021) to 78.5 kBtu/ft² (2022), an 17% increase.
What does an ENERGY STAR score of 65 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 65 means the building performs better than about 65% of its national peers. BuildingCensus bands the score into report-card grades; 65 falls in band C — below median (55–69). It sits 10 points below 75, the threshold for ENERGY STAR certification. 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. Nobel Executive Center's 78.5 kBtu/ft² across 120,972 sq ft works out to about 9.5 billion Btu (2,783 MWh-equivalent) in 2022.
Which law requires Nobel Executive Center to report its energy use?
