Outcome Based Energy Codes

Seattle Pilot Project and the Vulcan Supply Laundry Demonstration Project

As a leading innovator in green building policy, Seattle is fertile ground for pioneering a new Outcome Based Energy Code Framework.  Since 2010, the Green Lab and City of Seattle have been conducting a demonstration project to evaluate the innovative energy code framework in three historic real estate projects. The objective is to identify solutions to help existing buildings achieve aggressive energy efficiency targets, while maximizing the value these building bring to communities and owners. 

The process:

  • Early development phase – PGL and the City of Seattle developed a draft code framework through a series of stakeholder meetings. The regional working group was comprised of energy efficiency experts, including PGL, New Buildings Institute (NBI), Cities of Vancouver (BC) and Seattle, Northwest Energy Efficiency Alliance (NEEA), Pacific Northwest National Laboratory (PNNL), Department of Energy (DOE), and Architecture 2030.
  • Demonstration project search—The Green Lab vetted more than 30 projects before selecting three demonstration projects in Seattle. 
  • Demonstration project program – The Supply Laundry Building, 1510 Melrose, and Anhalt Apartments have been taken through a draft outcome-based compliance path.
  • Codification - New Seattle Energy Code revisions based on the demonstration projects were unanimously approved by Seattle City Council and are effective on December 26, 2013.
  • National policy framework – The Green Lab and City of Seattle are leading the national conversation around outcome-based codes and developing the components of proposed compliance paths for the International Green Construction Code (IgCC), International Energy Efficiency Code (IECC), and Washington State Energy Code 2015 revisions. We are seeking other demonstration partners throughout the country.

The code development process includes use of demonstration projects to test the code’s application. Vulcan Real Estate's Supply Laundry Building, a 100-year-old former industrial laundry recently renovated to speculative office and restaurant use, is targeting energy consumption reductions of more than 50 percent better than the national average for the project.   

Supply Laundry is an ideal project for this work. As a mid-sized brick building undergoing a substantial renovation and change-of-use, lessons learned from this project will be broadly applicable to much of the nation’s smaller, older building stock. The overall objective of Seattle’s pilot is to show that with a more flexible approach, owners of older buildings can achieve aggressive aggressive energy targets, retain valuable historic features and optimize return on investment in terms of both energy savings and dollars.
