How has I3Logix's energy performance changed over time?
BuildingCensus holds 3 Denver disclosures for I3Logix, covering report years 2021–2023. Its ENERGY STAR score went from 62 in 2021 to 64 in 2023 (+2 points). Site EUI moved from 87.4 kBtu/ft² (2021) to 85.6 kBtu/ft² (2023), a 2% decrease. Reported emissions went from 256 tCO₂e to 237 tCO₂e over the same span (down 7%).
What does an ENERGY STAR score of 64 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 64 means the building performs better than about 64% of its national peers. BuildingCensus bands the score into report-card grades; 64 falls in band C — below median (55–69). It sits 11 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. I3Logix's 85.6 kBtu/ft² across 29,413 sq ft works out to about 2.5 billion Btu (738 MWh-equivalent) in 2023. The disclosure also reports 297,056 kWh of electricity and 15,032 therms of natural gas for the year.
Which law requires I3Logix to report its energy use?
I3Logix 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:5554:2023). 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.
