How has Northwest: Pioneer Tower's energy performance changed over time?
BuildingCensus holds 6 California disclosures for Northwest: Pioneer Tower, covering report years 2019–2024. Its ENERGY STAR score went from 76 in 2019 to 81 in 2024 (+5 points); its best year on file was 2022, at 99. Site EUI moved from 46.1 kBtu/ft² (2019) to 45.5 kBtu/ft² (2024), a 1% decrease. Reported emissions went from 408 tCO₂e to 423 tCO₂e over the same span (up 4%).
What does an ENERGY STAR score of 81 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 81 means the building performs better than about 81% of its national peers. BuildingCensus bands the score into report-card grades; 81 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. Northwest: Pioneer Tower's 45.5 kBtu/ft² across 156,539 sq ft works out to about 7.1 billion Btu (2,087 MWh-equivalent) in 2024. The disclosure also reports 1,000,740 kWh of electricity and 37,017 therms of natural gas for the year.
