How does Halfon Candy Co. compare with other non-refrigerated warehouse buildings in Seattle?
The latest disclosures cover 164 non-refrigerated warehouse buildings in Seattle, out of 3,871 buildings citywide. Halfon Candy Co.'s ENERGY STAR score of 44 compares with an average of 58 across the 117 that report a score; it scores higher than 30% of them and lower than 69%. Its site EUI of 53.3 kBtu/ft² is about 75% above the average of 30.5 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 2.7 kgCO₂e/ft² is about 198% above the group average of 0.9 kgCO₂e/ft².
At 31,300 sq ft, it is about half of the average floor area of 58,727 sq ft for those buildings. It was built in 1978, 18 years later than the group's average year built (1960). Across all 24 jurisdictions BuildingCensus covers, the 4,723 non-refrigerated warehouse buildings average an ENERGY STAR score of 66 and a site EUI of 26.0 kBtu/ft².
How has Halfon Candy Co.'s energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Halfon Candy Co., covering report years 2015–2025. Its ENERGY STAR score went from 91 in 2015 to 44 in 2025 (-47 points); its best year on file was 2016, at 92. Site EUI moved from 9.7 kBtu/ft² (2015) to 53.3 kBtu/ft² (2025), an 449% increase. Reported emissions went from 7 tCO₂e to 84 tCO₂e over the same span (up 1190%).
What does an ENERGY STAR score of 44 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 44 means the building performs better than about 44% of its national peers. BuildingCensus bands the score into report-card grades; 44 falls in band D — lowest band (1–54). It sits 31 points below 75, the threshold for ENERGY STAR certification. In Seattle, 69% 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. Halfon Candy Co.'s 53.3 kBtu/ft² across 31,300 sq ft works out to about 1.7 billion Btu (489 MWh-equivalent) in 2025. Its source EUI of 60.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 21,190 kWh of electricity and 15,966 therms of natural gas for the year.
Which law requires Halfon Candy Co. to report its energy use?
Halfon Candy Co. reports under the Seattle Energy Benchmarking Ordinance (SMC 22.920), the legal basis of Seattle's Building Energy Benchmarking program, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2025 disclosure (source record seattle:21898:2025). Seattle's Building Emissions Performance Standard (adopted 2023) applies to buildings over 20,000 sq ft: benchmarking verification is due 2027–2030 and initial emissions targets 2031–2035, reaching net zero by 2041–2050, with fines for non-compliance.
