Eccu I

How does Eccu I compare with other office buildings in California?

The latest disclosures cover 6,214 office buildings in California, out of 40,029 buildings citywide. Eccu I's ENERGY STAR score of 81 compares with an average of 75 across the 4,912 that report a score; it scores higher than 44% of them and lower than 54%. Its site EUI of 48.6 kBtu/ft² is about 14% below the average of 56.4 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 3.4 kgCO₂e/ft² is roughly in line with the group average of 3.6 kgCO₂e/ft².

At 106,728 sq ft, it is about 30% below the average floor area of 151,937 sq ft for those buildings. It was built in 2002, 17 years later than the group's average year built (1985). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².

How has Eccu I's energy performance changed over time?

BuildingCensus holds 2 California disclosures for Eccu I, covering report years 2018–2019. Its ENERGY STAR score went from 79 in 2018 to 81 in 2019 (+2 points). Site EUI moved from 51.9 kBtu/ft² (2018) to 48.6 kBtu/ft² (2019), a 6% decrease. Reported emissions went from 390 tCO₂e to 365 tCO₂e over the same span (down 6%).

What does an ENERGY STAR score of 81 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 81 means the building performs better than about 81% of its national peers. BuildingCensus bands the score into report-card grades; 81 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 I's 48.6 kBtu/ft² across 106,728 sq ft works out to about 5.2 billion Btu (1,520 MWh-equivalent) in 2019. The disclosure also reports 1,518,549 kWh of electricity for the year.

Which law requires Eccu I to report its energy use?

Eccu I 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:4156202:2019). AB 802 requires every California commercial building over 50,000 sq ft to report energy use to the CEC annually; the CEC publicly discloses the results statewide.
