Its ENERGY STAR score went from 87 in 2021 to 67 in 2023 (-20 points); its best year on file was 2021, at 87. Site EUI moved from 35.3 kBtu/ft² (2021) to 47.8 kBtu/ft² (2023), an 35% increase. Reported emissions went from 276 tCO₂e to 293 tCO₂e over the same span (up 6%).
What does an ENERGY STAR score of 67 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 67 means the building performs better than about 67% of its national peers. BuildingCensus bands the score into report-card grades; 67 falls in band C — below median (55–69). It sits 8 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. Observatory Flats Community's 47.8 kBtu/ft² across 58,531 sq ft works out to about 2.8 billion Btu (820 MWh-equivalent) in 2023. The disclosure also reports 416,647 kWh of electricity and 13,734 therms of natural gas for the year.
