Join the Challenge

Benefits 
  • Identification as a change agent and market leader.

  • Promotion on the 20 by 2020 website and in media campaigns.

  • Recognition at events and in communications by King County and Challenge partners.

  • Preparation for Washington's regulatory requirements as energy code progresses to Passive House-levels of building performance by 2030.

Assistance + Incentives

The City of Seattle offers expedited permitting (Priority Green Expedited) and zoning incentives (SDCI Director’s Rule 20-2017) for Passive House. Seattle City Light’s Energy Efficiency as a Service program provides utility payments to investors in building efficiency, providing building owners with a new revenue stream for Passive House projects. Outside Seattle, various municipalities in King County are considering new Passive House policy and incentives.

To achieve the Challenge, applicants must have, by December 31, 2020, submitted a letter of commitment and evidence of: (1) building permit submittal; and (2) Passive House performance modeling results by a certified professional showing compliance with Passive House targets (PHIUS or PHI); and 3) confirmation that the project is 20,000 square feet or larger and sited in King County.
