How has Carillon Tower's energy performance changed over time?
BuildingCensus holds 5 California disclosures for Carillon Tower, covering report years 2020–2024. Its ENERGY STAR score went from 71 in 2020 to 76 in 2024 (+5 points). Site EUI moved from 42.8 kBtu/ft² (2020) to 41.3 kBtu/ft² (2024), a 4% decrease. Reported emissions went from 278 tCO₂e to 285 tCO₂e over the same span (up 3%).
What does an ENERGY STAR score of 76 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 76 means the building performs better than about 76% of its national peers. BuildingCensus bands the score into report-card grades; 76 falls in band B — above median (70–84). 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. Carillon Tower's 41.3 kBtu/ft² across 113,527 sq ft works out to about 4.7 billion Btu (1,374 MWh-equivalent) in 2024. The disclosure also reports 737,658 kWh of electricity and 22,142 therms of natural gas for the year.
Which law requires Carillon Tower to report its energy use?
