How has Galaxy I Concord Corporation's energy performance changed over time?
BuildingCensus holds 7 California disclosures for Galaxy I Concord Corporation, covering report years 2018–2024. Its ENERGY STAR score went from 76 in 2018 to 98 in 2024 (+22 points); its best year on file was 2019, at 99. Site EUI moved from 51.0 kBtu/ft² (2018) to 28.5 kBtu/ft² (2024), a 44% decrease. Reported emissions went from 245 tCO₂e to 205 tCO₂e over the same span (down 17%).
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. Galaxy I Concord Corporation's 28.5 kBtu/ft² across 116,089 sq ft works out to about 3.3 billion Btu (970 MWh-equivalent) in 2024. The disclosure also reports 579,724 kWh of electricity and 13,794 therms of natural gas for the year.
