How does One Dtc West compare with other office buildings in Denver?
The latest disclosures cover 427 office buildings in Denver, out of 3,287 buildings citywide. One Dtc West's ENERGY STAR score of 56 compares with an average of 71 across the 339 that report a score; it scores higher than 18% of them and lower than 80%. Its site EUI of 72.2 kBtu/ft² is roughly in line with the average of 67.1 kBtu/ft².
At 75,168 sq ft, it is about half of the average floor area of 157,927 sq ft for those buildings. It was built in 2018, 38 years later than the group's average year built (1980). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².
What does an ENERGY STAR score of 56 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 56 means the building performs better than about 56% of its national peers. BuildingCensus bands the score into report-card grades; 56 falls in band C — below median (55–69). It sits 19 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. One Dtc West's 72.2 kBtu/ft² across 75,168 sq ft works out to about 5.4 billion Btu (1,591 MWh-equivalent) in 2023. The disclosure also reports 1,426,108 kWh of electricity and 5,600 therms of natural gas for the year.
Which law requires One Dtc West to report its energy use?
