How has Santiago Hs's energy performance changed over time?
BuildingCensus holds 3 California disclosures for Santiago Hs, covering report years 2022–2024. Its ENERGY STAR score went from 42 in 2022 to 45 in 2024 (+3 points). Site EUI moved from 49.4 kBtu/ft² (2022) to 46.3 kBtu/ft² (2024), a 6% decrease. Reported emissions went from 911 tCO₂e to 889 tCO₂e over the same span (down 2%).
What does an ENERGY STAR score of 45 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 45 means the building performs better than about 45% of its national peers. BuildingCensus bands the score into report-card grades; 45 falls in band D — lowest band (1–54). It sits 30 points below 75, the threshold for ENERGY STAR certification. 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. Santiago Hs's 46.3 kBtu/ft² across 300,804 sq ft works out to about 13.9 billion Btu (4,082 MWh-equivalent) in 2024. The disclosure also reports 2,313,099 kWh of electricity and 68,725 therms of natural gas for the year.
Which law requires Santiago Hs to report its energy use?
Santiago Hs 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:27674391:2024). 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.
