Its ENERGY STAR score went from 96 in 2019 to 100 in 2024 (+4 points); its best year on file was 2020, at 100. Site EUI moved from 20.1 kBtu/ft² (2019) to 14.6 kBtu/ft² (2024), a 27% decrease. Reported emissions went from 82 tCO₂e to 77 tCO₂e over the same span (down 6%).
What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 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. The Wilson (Wl100)'s 14.6 kBtu/ft² across 81,541 sq ft works out to about 1.2 billion Btu (349 MWh-equivalent) in 2024. The disclosure also reports 311,934 kWh of electricity and 1,213 therms of natural gas for the year.
