How has 1800 Glenarm Pl's energy performance changed over time?
BuildingCensus holds 3 Denver disclosures for 1800 Glenarm Pl, covering report years 2021–2023. Its ENERGY STAR score went from 57 in 2021 to 76 in 2023 (+19 points).

What does an ENERGY STAR score of 76 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 76 means the building performs better than about 76% of its national peers. BuildingCensus bands the score into report-card grades; 76 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. 1800 Glenarm Pl's 51.7 kBtu/ft² across 71,432 sq ft works out to about 3.7 billion Btu (1,082 MWh-equivalent) in 2023. The disclosure also reports 714,356 kWh of electricity and 12,524 therms of natural gas for the year.
