Seattle's Energy Hogs Built in 1960s to 1980s
Energy reporting in the Emerald City reveals 41% of large buildings are Energy Stars, while the most wasteful buildings could save millions on energy bills.Owners of the worst-performing buildings in Seattle could save $55 million a year by reducing their energy use 25%, according to a report released by the City. Seattle is one of a handful of municipalities in the U.S. that mandate annual building benchmarking and disclosure (see “ ”).
Among those cities, Seattle claims the highest compliance rate: 93% of building owners required to disclose actually did so in 2012, making data available from 2,600 commercial and multifamily buildings 20,000 ft2 and larger. The report found that just 18% of those buildings had Energy Star certification, even though 41% would qualify for certification due to benchmarking scores of 75 or higher (meaning they perform better than 75% of U.S. buildings of the same type). In fact, Seattle buildings overall had a mean Energy Star score of 68.
Grocery stores, hospitals, and courthouses showed the highest median energy use intensity (EUI)—with supermarkets topping 215 kBtu/ft2—while the median EUI for multifamily housing (at 31.9) was almost as low as that of warehouses (30.4).
Office buildings were in between, with a median EUI of 59.7, though results varied by age. “Office building energy performance was worst for mid-century buildings built between the 1960s and 1980s,” the report states, “but better for those constructed earlier and for those built since 2000.”
