Its site EUI of 6.5 kBtu/ft² is about 87% below the average of 49.2 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.4 kgCO₂e/ft² is about 87% below the group average of 2.7 kgCO₂e/ft².

At 48,612 sq ft, it is about half of the average floor area of 107,408 sq ft for those buildings. It was built in 1953, 12 years later than the group's average year built (1941). Across all 24 jurisdictions BuildingCensus covers, the 2,307 commercial buildings average an ENERGY STAR score of 76 and a site EUI of 51.3 kBtu/ft².

How has 800 CESAR CHAVEZ ST's energy performance changed over time?

BuildingCensus holds 3 San Francisco disclosures for 800 CESAR CHAVEZ ST, covering report years 2023–2025. Its ENERGY STAR score went from 56 in 2023 to 95 in 2025 (+39 points).

What does an ENERGY STAR score of 95 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 95 means the building performs better than about 95% of its national peers. BuildingCensus bands the score into report-card grades; 95 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 San Francisco, 73% 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. 800 CESAR CHAVEZ ST's 6.5 kBtu/ft² across 48,612 sq ft works out to about 0.3 billion Btu (93 MWh-equivalent) in 2025. Its source EUI of 12.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 45,066 kWh of electricity and 1,639 therms of natural gas for the year.

Which law requires 800 CESAR CHAVEZ ST to report its energy use?

800 CESAR CHAVEZ ST reports under SF Environment Code Chapter 20, the legal basis of San Francisco's Existing Buildings Energy Performance Ordinance, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2025 disclosure (source record sf:4310/003:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
