How has Human Services Agency Headquarters's energy performance changed over time?
BuildingCensus holds 4 California disclosures for Human Services Agency Headquarters, covering report years 2019–2022. Its ENERGY STAR score went from 73 in 2019 to 88 in 2022 (+15 points).

What does an ENERGY STAR score of 88 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 88 means the building performs better than about 88% of its national peers. BuildingCensus bands the score into report-card grades; 88 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. Human Services Agency Headquarters's 45.1 kBtu/ft² across 136,385 sq ft works out to about 6.2 billion Btu (1,803 MWh-equivalent) in 2022. The disclosure also reports 1,564,824 kWh of electricity and 8,336 therms of natural gas for the year.
Which law requires Human Services Agency Headquarters to report its energy use?
