Across all 24 jurisdictions BuildingCensus covers, the 6,548 K-12 school buildings average an ENERGY STAR score of 64 and a site EUI of 52.7 kBtu/ft².
How has Hawking STEAM Charter School 2's energy performance changed over time?
BuildingCensus holds 2 San Diego disclosures for Hawking STEAM Charter School 2, covering report years 2021–2022. Only one of those years carries energy figures.
What does an ENERGY STAR score of 80 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 80 means the building performs better than about 80% of its national peers. BuildingCensus bands the score into report-card grades; 80 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 San Diego, 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. Hawking STEAM Charter School 2's 18.0 kBtu/ft² across 79,328 sq ft works out to about 1.4 billion Btu (418 MWh-equivalent) in 2022.
Which law requires Hawking STEAM Charter School 2 to report its energy use?
Hawking STEAM Charter School 2 reports under the Building Energy Benchmarking Ordinance (SDMC Ch. 14 Art. 12), the legal basis of San Diego's Building Energy Benchmarking program, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2022 disclosure (source record san_diego:100084:2022). San Diego's ordinance requires annual benchmarking for commercial buildings over 50,000 sq ft, with civil penalties for buildings that fail to report.
