How has Redwood Gardens's energy performance changed over time?
BuildingCensus holds 3 California disclosures for Redwood Gardens, covering report years 2022–2024. Its ENERGY STAR score went from 97 in 2022 to 98 in 2024 (+1 points). Site EUI moved from 24.2 kBtu/ft² (2022) to 22.3 kBtu/ft² (2024), a 8% decrease. Reported emissions went from 186 tCO₂e to 191 tCO₂e over the same span (up 3%).
What does an ENERGY STAR score of 98 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 98 means the building performs better than about 98% of its national peers. BuildingCensus bands the score into report-card grades; 98 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. Redwood Gardens's 22.3 kBtu/ft² across 125,813 sq ft works out to about 2.8 billion Btu (822 MWh-equivalent) in 2024. The disclosure also reports 440,566 kWh of electricity for the year.
Which law requires Redwood Gardens to report its energy use?
