How has Irv - Monterey's energy performance changed over time?

BuildingCensus holds 3 California disclosures for Irv - Monterey, covering report years 2022–2024. Its ENERGY STAR score went from 100 in 2022 to 90 in 2024 (-10 points); its best year on file was 2022, at 100. Site EUI moved from 25.8 kBtu/ft² (2022) to 35.3 kBtu/ft² (2024), an 37% increase. Reported emissions went from 98 tCO₂e to 142 tCO₂e over the same span (up 44%).

What does an ENERGY STAR score of 90 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 90 means the building performs better than about 90% of its national peers. BuildingCensus bands the score into report-card grades; 90 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. Irv - Monterey's 35.3 kBtu/ft² across 86,445 sq ft works out to about 3.1 billion Btu (894 MWh-equivalent) in 2024. The disclosure also reports 486,152 kWh of electricity and 6,003 therms of natural gas for the year.
