How has Pasadena Office Tower's energy performance changed over time?
BuildingCensus holds 2 California disclosures for Pasadena Office Tower, covering report years 2023–2024. Its ENERGY STAR score went from 75 in 2023 to 78 in 2024 (+3 points). Site EUI moved from 55.6 kBtu/ft² (2023) to 53.0 kBtu/ft² (2024), a 5% decrease. Reported emissions went from 519 tCO₂e to 511 tCO₂e over the same span (down 1%).
What does an ENERGY STAR score of 78 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 78 means the building performs better than about 78% of its national peers. BuildingCensus bands the score into report-card grades; 78 falls in band B — above median (70–84). 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. Pasadena Office Tower's 53.0 kBtu/ft² across 145,260 sq ft works out to about 7.7 billion Btu (2,256 MWh-equivalent) in 2024. The disclosure also reports 2,257,324 kWh of electricity for the year.
Which law requires Pasadena Office Tower to report its energy use?
Pasadena Office 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.
