Its ENERGY STAR score went from 40 in 2021 to 48 in 2023 (+8 points); its best year on file was 2022, at 49. Site EUI moved from 119.3 kBtu/ft² (2021) to 126.2 kBtu/ft² (2023), an 6% increase. Reported emissions went from 305 tCO₂e to 309 tCO₂e over the same span (up 1%).
What does an ENERGY STAR score of 48 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 48 means the building performs better than about 48% of its national peers. BuildingCensus bands the score into report-card grades; 48 falls in band D — lowest band (1–54). It sits 27 points below 75, the threshold for ENERGY STAR certification. In Denver, 54% 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. 3400 Bayaud's 126.2 kBtu/ft² across 28,466 sq ft works out to about 3.6 billion Btu (1,053 MWh-equivalent) in 2023. The disclosure also reports 340,413 kWh of electricity and 24,309 therms of natural gas for the year.
