Tasman 2

How does Tasman 2 compare with other office buildings in California?

The latest disclosures cover 6,214 office buildings in California, out of 40,029 buildings citywide. Tasman 2's ENERGY STAR score of 92 compares with an average of 75 across the 4,912 that report a score; it scores higher than 69% of them and lower than 28%. Its site EUI of 34.0 kBtu/ft² is about 40% 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 2.2 kgCO₂e/ft² is about 39% below the group average of 3.6 kgCO₂e/ft².

At 180,926 sq ft, it is about 19% above the average floor area of 151,937 sq ft for those buildings. It was built in 2022, 37 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.

What does an ENERGY STAR score of 92 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 92 means the building performs better than about 92% of its national peers. BuildingCensus bands the score into report-card grades; 92 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. Tasman 2's 34.0 kBtu/ft² across 180,926 sq ft works out to about 6.2 billion Btu (1,803 MWh-equivalent) in 2022. The disclosure also reports 1,408,827 kWh of electricity and 13,483 therms of natural gas for the year.

Which law requires Tasman 2 to report its energy use?

Tasman 2 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 2022 disclosure (source record california:25429494:2022). 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.
