What does an ENERGY STAR score of 61 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 61 means the building performs better than about 61% of its national peers. BuildingCensus bands the score into report-card grades; 61 falls in band C — below median (55–69). It sits 14 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. 6850 Argonne Denver Airport Business Park's 76.4 kBtu/ft² across 38,264 sq ft works out to about 2.9 billion Btu (857 MWh-equivalent) in 2023. The disclosure also reports 212,680 kWh of electricity and 21,971 therms of natural gas for the year.
