What does an ENERGY STAR score of 84 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 84 means the building performs better than about 84% of its national peers. BuildingCensus bands the score into report-card grades; 84 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. Viano At Riverwalk (Vn362)'s 29.9 kBtu/ft² across 249,407 sq ft works out to about 7.5 billion Btu (2,186 MWh-equivalent) in 2024. The disclosure also reports 2,011,985 kWh of electricity and 6,366 therms of natural gas for the year.

Which law requires Viano At Riverwalk (Vn362) to report its energy use?

Viano At Riverwalk (Vn362) 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:20971122:2024). 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.
