Its ENERGY STAR score went from 84 in 2021 to 73 in 2023 (-11 points); its best year on file was 2021, at 84. Site EUI moved from 41.2 kBtu/ft² (2021) to 55.9 kBtu/ft² (2023), an 36% increase. Reported emissions went from 130 tCO₂e to 155 tCO₂e over the same span (up 19%).
What does an ENERGY STAR score of 73 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 73 means the building performs better than about 73% of its national peers. BuildingCensus bands the score into report-card grades; 73 falls in band B — above median (70–84). It sits 2 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. 1055 Auraria's 55.9 kBtu/ft² across 28,313 sq ft works out to about 1.6 billion Btu (464 MWh-equivalent) in 2023. The disclosure also reports 204,755 kWh of electricity and 8,844 therms of natural gas for the year.
