Reported emissions went from 292 tCO₂e to 281 tCO₂e over the same span (down 4%).

What does an ENERGY STAR score of 85 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 85 means the building performs better than about 85% of its national peers. BuildingCensus bands the score into report-card grades; 85 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. The Vineyards (Vn211)'s 28.9 kBtu/ft² across 139,108 sq ft works out to about 4 billion Btu (1,178 MWh-equivalent) in 2023. The disclosure also reports 1,105,791 kWh of electricity and 2,532 therms of natural gas for the year.

Which law requires The Vineyards (Vn211) to report its energy use?

The Vineyards (Vn211) 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 2023 disclosure (source record california:10170242:2023). 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.
