Seattle Proposes Update to Energy Code to Electrify Buildings and Restrict Fossil Fuels

Strategic Insights -

As the world grapples with the impacts of climate change, Seattle is taking bold steps to reduce its greenhouse gas emissions. Mayor Jenny A. Durkan has transmitted a proposed update to the energy code to the City Council, which would further electrify buildings using clean energy and restrict fossil fuels for most building use. This move aims to cut down on the significant emissions contributed by the building sector, with space and water heating accounting for most building gas use. The proposed update is part of the City's commitment to the Seattle Green New Deal, which seeks to create a more equitable and sustainable future for all residents.

Key Takeaways:

  • The proposed update to the Seattle Energy Code would eliminate most gas and electric resistance space heating systems in commercial and large multifamily buildings.
  • The code would also eliminate gas water heating in large multifamily buildings and hotels, and improve building exteriors to increase energy efficiency and comfort.
  • The update would create opportunities for solar power and require electrical infrastructure necessary for future conversion of any gas appliances in multifamily buildings.
  • The proposed code changes were recommended for approval by the Seattle Construction Codes Advisory Board (CCAB) and are being supported by the Bloomberg Philanthropies American Cities Climate Challenge.
  • The City aims to eliminate most direct carbon emissions from new commercial and multifamily buildings, with the most economical opportunity to transition to clean electricity being at construction.
  • If the proposed code changes are not implemented, the City expects greenhouse gas emissions from buildings to be at least 12% higher by 2050.

Statistics:

  • The City of Seattle has helped approximately 600 households convert from dirty, inefficient heating oil to clean, energy-efficient heat pumps since 2017.
  • Building owners have found operational efficiencies and low- and no-cost fixes through Building Tune-Ups, resulting in a 10-15% reduction in building emissions on average.
  • 450 tune-ups have been completed by Seattle's largest buildings to date, reducing greenhouse gas emissions across the city and saving money on energy bills.
  • The proposed Seattle Energy Code impacts new construction and substantial alterations of commercial and 4+ story tall multi-family buildings.
  • 25 cities are participating in the Bloomberg Philanthropies American Cities Climate Challenge, which Seattle is a part of.
