Stanford Place Iii's ENERGY STAR score of 86 compares with an average of 71 across the 339 that report a score; it scores higher than 73% of them and lower than 22%. Its site EUI of 39.1 kBtu/ft² is about 42% below the average of 67.1 kBtu/ft² — it uses less energy per square foot than the typical building in that group.
At 403,626 sq ft, it is about 156% above the average floor area of 157,927 sq ft for those buildings. Its 1982 construction date is close to 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.
How has Stanford Place Iii's energy performance changed over time?
BuildingCensus holds 3 Denver disclosures for Stanford Place Iii, covering report years 2021–2023. Its ENERGY STAR score went from 87 in 2021 to 86 in 2023 (-1 points); its best year on file was 2021, at 87. Site EUI moved from 44.0 kBtu/ft² (2021) to 39.1 kBtu/ft² (2023), a 11% decrease. Reported emissions went from 2,909 tCO₂e to 2,408 tCO₂e over the same span (down 17%).
What does an ENERGY STAR score of 86 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 86 means the building performs better than about 86% of its national peers. BuildingCensus bands the score into report-card grades; 86 falls in band A — high performer (85–100). 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. Stanford Place Iii's 39.1 kBtu/ft² across 403,626 sq ft works out to about 15.8 billion Btu (4,625 MWh-equivalent) in 2023. The disclosure also reports 4,551,858 kWh of electricity and 0 therms of natural gas for the year.
Which law requires Stanford Place Iii to report its energy use?
Stanford Place Iii reports under the Energize Denver Building Performance Policy, the legal basis of Denver's Energize Denver Benchmarking program, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2023 disclosure (source record denver:5668:2023). Energize Denver sets energy-use (EUI) targets for buildings of 25,000+ sq ft — for most buildings an interim target in 2028 and a final target in 2032 — with civil penalties of roughly $0.15–0.35 per kBtu over target for non-compliance.
