What does an ENERGY STAR score of 65 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 65 means the building performs better than about 65% of its national peers. BuildingCensus bands the score into report-card grades; 65 falls in band C — below median (55–69). It sits 10 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. Manchester Apartments's 95.2 kBtu/ft² across 103,437 sq ft works out to about 9.8 billion Btu (2,886 MWh-equivalent) in 2023. The disclosure also reports 535,615 kWh of electricity and 80,170 therms of natural gas for the year.

Which law requires Manchester Apartments to report its energy use?

Manchester Apartments 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:2930:2023). 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.
