How has Alliance Center Operations's energy performance changed over time?
BuildingCensus holds 3 Denver disclosures for Alliance Center Operations, covering report years 2021–2023. Its ENERGY STAR score went from 71 in 2021 to 80 in 2023 (+9 points). Site EUI moved from 33.2 kBtu/ft² (2021) to 33.0 kBtu/ft² (2023), a 1% decrease. Reported emissions went from 223 tCO₂e to 215 tCO₂e over the same span (down 4%).
What does an ENERGY STAR score of 80 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 80 means the building performs better than about 80% of its national peers. BuildingCensus bands the score into report-card grades; 80 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. Alliance Center Operations's 33.0 kBtu/ft² across 40,393 sq ft works out to about 1.3 billion Btu (391 MWh-equivalent) in 2023. The disclosure also reports 405,514 kWh of electricity and 0 therms of natural gas for the year.
Which law requires Alliance Center Operations to report its energy use?
