How has 111 Santa Rosa Llc's energy performance changed over time?

BuildingCensus holds 4 California disclosures for 111 Santa Rosa Llc, covering report years 2021–2024. Its ENERGY STAR score went from 85 in 2022 to 88 in 2024 (+3 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. 111 Santa Rosa Llc's 28.1 kBtu/ft² across 64,221 sq ft works out to about 1.8 billion Btu (529 MWh-equivalent) in 2024. The disclosure also reports 449,460 kWh of electricity and 4,359 therms of natural gas for the year.
