How has 117 Winston's energy performance changed over time?

Its ENERGY STAR score went from 92 in 2019 to 91 in 2024 (-1 points); its best year on file was 2022, at 98. Site EUI moved from 15.9 kBtu/ft² (2022) to 19.5 kBtu/ft² (2024), an 23% increase. Reported emissions went from 69 tCO₂e to 66 tCO₂e over the same span (down 3%).
What does an ENERGY STAR score of 91 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 91 means the building performs better than about 91% of its national peers. BuildingCensus bands the score into report-card grades; 91 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. 117 Winston's 19.5 kBtu/ft² across 52,080 sq ft works out to about 1 billion Btu (298 MWh-equivalent) in 2024. The disclosure also reports 293,210 kWh of electricity for the year.
