Walter Bros Construction Co Inc

How does Walter Bros Construction Co Inc compare with other office buildings in California?

The latest disclosures cover 6,214 office buildings in California, out of 40,029 buildings citywide. Walter Bros Construction Co Inc's ENERGY STAR score of 91 compares with an average of 75 across the 4,912 that report a score; it scores higher than 66% of them and lower than 31%. Its site EUI of 25.9 kBtu/ft² is about half of 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 1.6 kgCO₂e/ft² is about half of the group average of 3.6 kgCO₂e/ft².

At 53,253 sq ft, it is about 65% below the average floor area of 151,937 sq ft for those buildings. It was built in 1981, 4 years earlier 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.

What does an ENERGY STAR score of 91 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 91 means the building performs better than about 91% of its national peers. BuildingCensus bands the score into report-card grades; 91 falls in band A — high performer (85–100). 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. Walter Bros Construction Co Inc's 25.9 kBtu/ft² across 53,253 sq ft works out to about 1.4 billion Btu (404 MWh-equivalent) in 2024. The disclosure also reports 332,994 kWh of electricity and 2,372 therms of natural gas for the year.

Which law requires Walter Bros Construction Co Inc to report its energy use?

Walter Bros Construction Co Inc 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:15928031:2024). 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.
