How has Palo Alto Square 5's energy performance changed over time?
BuildingCensus holds 5 California disclosures for Palo Alto Square 5, covering report years 2018, 2020, 2021, 2023, 2024. Its ENERGY STAR score was 87 in both 2018 and 2024.

What does an ENERGY STAR score of 87 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 87 means the building performs better than about 87% of its national peers. BuildingCensus bands the score into report-card grades; 87 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. Palo Alto Square 5's 34.1 kBtu/ft² across 138,650 sq ft works out to about 4.7 billion Btu (1,386 MWh-equivalent) in 2024. The disclosure also reports 1,289,171 kWh of electricity for the year.
