How has 11854 Lagrange Ave (Westgate)'s energy performance changed over time?
BuildingCensus holds 4 California disclosures for 11854 Lagrange Ave (Westgate), covering report years 2018–2021. Its ENERGY STAR score went from 86 in 2018 to 99 in 2021 (+13 points). Site EUI moved from 32.7 kBtu/ft² (2018) to 18.2 kBtu/ft² (2021), a 44% decrease. Reported emissions went from 323 tCO₂e to 167 tCO₂e over the same span (down 48%).
What does an ENERGY STAR score of 99 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 99 means the building performs better than about 99% of its national peers. BuildingCensus bands the score into report-card grades; 99 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. 11854 Lagrange Ave (Westgate)'s 18.2 kBtu/ft² across 134,193 sq ft works out to about 2.4 billion Btu (716 MWh-equivalent) in 2021. The disclosure also reports 705,743 kWh of electricity and 306 therms of natural gas for the year.
Which law requires 11854 Lagrange Ave (Westgate) to report its energy use?
