How has Mesa Labworks's energy performance changed over time?
BuildingCensus holds 5 California disclosures for Mesa Labworks, covering report years 2019, 2020, 2021, 2022, 2024. Its ENERGY STAR score went from 87 in 2019 to 100 in 2024 (+13 points). Site EUI moved from 30.5 kBtu/ft² (2019) to 9.5 kBtu/ft² (2024), a 69% decrease. Reported emissions went from 127 tCO₂e to 38 tCO₂e over the same span (down 70%).
What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 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. Mesa Labworks's 9.5 kBtu/ft² across 60,518 sq ft works out to about 0.6 billion Btu (168 MWh-equivalent) in 2024. The disclosure also reports 169,129 kWh of electricity and 3 therms of natural gas for the year.
Which law requires Mesa Labworks to report its energy use?
Mesa Labworks reports under AB 802 (Public Resources Code §25402.10), the legal basis of California's Building Energy Benchmarking Program (statewide), which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2024 disclosure (source record california:9569184:2024).
