How has Ascent's energy performance changed over time?
BuildingCensus holds 2 California disclosures for Ascent, covering report years 2023–2024. Its ENERGY STAR score went from 44 in 2023 to 61 in 2024 (+17 points). Site EUI moved from 30.6 kBtu/ft² (2023) to 28.2 kBtu/ft² (2024), a 8% decrease. Reported emissions went from 210 tCO₂e to 184 tCO₂e over the same span (down 12%).
What does an ENERGY STAR score of 61 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 61 means the building performs better than about 61% of its national peers. BuildingCensus bands the score into report-card grades; 61 falls in band C — below median (55–69). It sits 14 points below 75, the threshold for ENERGY STAR certification. 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. Ascent's 28.2 kBtu/ft² across 109,150 sq ft works out to about 3.1 billion Btu (902 MWh-equivalent) in 2024. The disclosure also reports 363,568 kWh of electricity and 19,178 therms of natural gas for the year.
Which law requires Ascent to report its energy use?
Ascent 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 2024 disclosure (source record california:34521927:2024).
