How does Blake Street compare with other office buildings in Denver?
The latest disclosures cover 427 office buildings in Denver, out of 3,287 buildings citywide. Blake Street's ENERGY STAR score of 72 compares with an average of 71 across the 339 that report a score; it scores higher than 38% of them and lower than 59%. Its site EUI of 67.0 kBtu/ft² is roughly in line with the average of 67.1 kBtu/ft² — it uses less energy per square foot than the typical building in that group.
At 71,708 sq ft, it is about half of the average floor area of 157,927 sq ft for those buildings. It was built in 1880, 100 years earlier 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 72 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 72 means the building performs better than about 72% of its national peers. BuildingCensus bands the score into report-card grades; 72 falls in band B — above median (70–84). It sits 3 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. Blake Street's 67.0 kBtu/ft² across 71,708 sq ft works out to about 4.8 billion Btu (1,408 MWh-equivalent) in 2021. The disclosure also reports 715,517 kWh of electricity and 20,501 therms of natural gas for the year.
Which law requires Blake Street to report its energy use?
