The latest disclosures cover 1,108 multifamily housing buildings in Denver, out of 3,287 buildings citywide. Line 28 At Lohi (Lz20)'s ENERGY STAR score of 64 compares with an average of 78 across the 956 that report a score; it scores higher than 21% of them and lower than 77%. Its site EUI of 83.6 kBtu/ft² is about 47% above the average of 57.0 kBtu/ft² — it uses more energy per square foot than the typical building in that group.

At 116,708 sq ft, it is roughly in line with the average floor area of 126,139 sq ft for those buildings. It was built in 2013, 23 years later than the group's average year built (1990). Across all 24 jurisdictions BuildingCensus covers, the 59,945 multifamily housing buildings average an ENERGY STAR score of 70 and a site EUI of 59.0 kBtu/ft².

How has Line 28 At Lohi (Lz20)'s energy performance changed over time?

BuildingCensus holds 3 Denver disclosures for Line 28 At Lohi (Lz20), covering report years 2021–2023. Its ENERGY STAR score went from 95 in 2021 to 64 in 2023 (-31 points); its best year on file was 2021, at 95. Site EUI moved from 45.7 kBtu/ft² (2021) to 83.6 kBtu/ft² (2023), an 83% increase. Reported emissions went from 892 tCO₂e to 839 tCO₂e over the same span (down 6%).

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. Line 28 At Lohi (Lz20)'s 83.6 kBtu/ft² across 116,708 sq ft works out to about 9.8 billion Btu (2,859 MWh-equivalent) in 2023. The disclosure also reports 920,703 kWh of electricity and 66,211 therms of natural gas for the year.

Which law requires Line 28 At Lohi (Lz20) to report its energy use?

Line 28 At Lohi (Lz20) 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:2278:2023). 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.
