How has No 25 Downing Condominiums's energy performance changed over time?
BuildingCensus holds 3 Denver disclosures for No 25 Downing Condominiums, covering report years 2021–2023. Its ENERGY STAR score went from 68 in 2021 to 81 in 2023 (+13 points).

What does an ENERGY STAR score of 81 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 81 means the building performs better than about 81% of its national peers. BuildingCensus bands the score into report-card grades; 81 falls in band B — above median (70–84). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. 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. No 25 Downing Condominiums's 50.1 kBtu/ft² across 125,345 sq ft works out to about 6.3 billion Btu (1,840 MWh-equivalent) in 2023. The disclosure also reports 1,029,488 kWh of electricity and 27,634 therms of natural gas for the year.
