What does a site EUI of 80.6 kBtu/ft² mean?
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. Leyden St's 80.6 kBtu/ft² across 57,388 sq ft works out to about 4.6 billion Btu (1,356 MWh-equivalent) in 2023. The disclosure also reports 91,281 kWh of electricity and 44,668 therms of natural gas for the year.
Which law requires Leyden St to report its energy use?
Leyden St 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:1468:2023). 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.
