At 59,940 sq ft, it is about 24% below the average floor area of 79,006 sq ft for those buildings. Its 1971 construction date is close to the group's average year built (1972). Across all 24 jurisdictions BuildingCensus covers, the 2,372 manufacturing/industrial plant buildings average an ENERGY STAR score of 67 and a site EUI of 126.3 kBtu/ft².
How has Gs 51St's energy performance changed over time?
BuildingCensus holds 3 Denver disclosures for Gs 51St, covering report years 2021–2023. Site EUI moved from 448.8 kBtu/ft² (2022) to 434.4 kBtu/ft² (2023), a 3% decrease. Reported emissions went from 3,816 tCO₂e to 3,667 tCO₂e over the same span (down 4%).
What does a site EUI of 434.4 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. Gs 51St's 434.4 kBtu/ft² across 59,940 sq ft works out to about 26 billion Btu (7,631 MWh-equivalent) in 2023. The disclosure also reports 6,566,670 kWh of electricity and 36,322 therms of natural gas for the year.
Which law requires Gs 51St to report its energy use?
Gs 51St 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:1232:2023). 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.
