What does an ENERGY STAR score of 64 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 64 means the building performs better than about 64% of its national peers. BuildingCensus bands the score into report-card grades; 64 falls in band C — below median (55–69). It sits 11 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. Columbine Towers's 76.3 kBtu/ft² across 123,354 sq ft works out to about 9.4 billion Btu (2,758 MWh-equivalent) in 2023. The disclosure also reports 874,648 kWh of electricity and 64,220 therms of natural gas for the year.
