How has Tribune Tower's energy performance changed over time?
BuildingCensus holds 6 California disclosures for Tribune Tower, covering report years 2018–2023. Its ENERGY STAR score was 100 in both 2018 and 2023. Site EUI moved from 26.5 kBtu/ft² (2019) to 23.6 kBtu/ft² (2023), a 11% decrease. Reported emissions went from 178 tCO₂e to 160 tCO₂e over the same span (down 10%).
What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 falls in band A — high performer (85–100). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. In California, 65% 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. Tribune Tower's 23.6 kBtu/ft² across 95,000 sq ft works out to about 2.2 billion Btu (657 MWh-equivalent) in 2023. The disclosure also reports 660,254 kWh of electricity for the year.
Which law requires Tribune Tower to report its energy use?
Tribune Tower reports under AB 802 (Public Resources Code §25402.10), the legal basis of California's Building Energy Benchmarking Program (statewide), which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2023 disclosure (source record california:9064288:2023).
