How has 101 N Montgomery's energy performance changed over time?
BuildingCensus holds 7 California disclosures for 101 N Montgomery, covering report years 2018–2024. Its ENERGY STAR score went from 42 in 2018 to 89 in 2024 (+47 points); its best year on file was 2023, at 89. Site EUI moved from 82.2 kBtu/ft² (2018) to 30.8 kBtu/ft² (2024), a 63% decrease. Reported emissions went from 353 tCO₂e to 134 tCO₂e over the same span (down 62%).
What does an ENERGY STAR score of 89 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 89 means the building performs better than about 89% of its national peers. BuildingCensus bands the score into report-card grades; 89 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. 101 N Montgomery's 30.8 kBtu/ft² across 66,000 sq ft works out to about 2 billion Btu (596 MWh-equivalent) in 2024. The disclosure also reports 590,685 kWh of electricity for the year.
Which law requires 101 N Montgomery to report its energy use?
101 N Montgomery 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:3535852:2024).
