How has Main Street Town Center's energy performance changed over time?
BuildingCensus holds 5 California disclosures for Main Street Town Center, covering report years 2018–2022. Its ENERGY STAR score went from 91 in 2018 to 93 in 2022 (+2 points).

What does an ENERGY STAR score of 93 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 93 means the building performs better than about 93% of its national peers. BuildingCensus bands the score into report-card grades; 93 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. Main Street Town Center's 27.1 kBtu/ft² across 220,453 sq ft works out to about 6 billion Btu (1,751 MWh-equivalent) in 2022. The disclosure also reports 1,700,120 kWh of electricity for the year.
