How has Eccu Iii's energy performance changed over time?
BuildingCensus holds 2 California disclosures for Eccu Iii, covering report years 2018–2019. Its ENERGY STAR score was 76 in both 2018 and 2019. Site EUI moved from 61.3 kBtu/ft² (2018) to 61.1 kBtu/ft² (2019), a 0% decrease. Reported emissions went from 360 tCO₂e to 351 tCO₂e over the same span (down 3%).
What does an ENERGY STAR score of 76 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 76 means the building performs better than about 76% of its national peers. BuildingCensus bands the score into report-card grades; 76 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. Eccu Iii's 61.1 kBtu/ft² across 82,150 sq ft works out to about 5 billion Btu (1,471 MWh-equivalent) in 2019. The disclosure also reports 1,448,927 kWh of electricity and 554 therms of natural gas for the year.
Which law requires Eccu Iii to report its energy use?
Eccu Iii 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 2019 disclosure (source record california:4156245:2019).
