Sumitomo Electric Device Innovations's ENERGY STAR score of 80 compares with an average of 75 across the 4,912 that report a score; it scores higher than 42% of them and lower than 56%. Its site EUI of 43.9 kBtu/ft² is about 22% 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 2.4 kgCO₂e/ft² is about 33% below the group average of 3.6 kgCO₂e/ft².
At 50,020 sq ft, it is about 67% below the average floor area of 151,937 sq ft for those buildings. Its 1982 construction date is close to 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 Sumitomo Electric Device Innovations's energy performance changed over time?
BuildingCensus holds 6 California disclosures for Sumitomo Electric Device Innovations, covering report years 2019–2024. Its ENERGY STAR score went from 89 in 2021 to 80 in 2024 (-9 points); its best year on file was 2021, at 89. Site EUI moved from 29.8 kBtu/ft² (2021) to 43.9 kBtu/ft² (2024), an 47% increase. Reported emissions went from 91 tCO₂e to 120 tCO₂e over the same span (up 33%).
What does an ENERGY STAR score of 80 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 80 means the building performs better than about 80% of its national peers. BuildingCensus bands the score into report-card grades; 80 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. Sumitomo Electric Device Innovations's 43.9 kBtu/ft² across 50,020 sq ft works out to about 2.2 billion Btu (644 MWh-equivalent) in 2024. The disclosure also reports 298,971 kWh of electricity for the year.
Which law requires Sumitomo Electric Device Innovations to report its energy use?
Sumitomo Electric Device Innovations 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:6798099:2024). 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.
