Passive House Helps Launch Zero Net Carbon Building Alliance

We know that buildings must play a starring role in climate solution-making in order to keep global warming to “well below 2 degrees Celsius.” A growing consensus is emerging that all new buildings need to be “Zero Net Carbon” (ZNC) by 2030, and all existing buildings must be ZNC by 2050, to reach our climate action goals. To this end, PHnw is co-organizing a new coalition of green building advocates, climate action organizations, and mission-driven businesses: the Zero Net Carbon Building Alliance. While the Alliance’s diverse organizations each have their own unique approach to sustainable construction, we share common ground (alarm about the climate crisis) and common cause (a ZNC built environment), that will allow us to speak policymakers with a common voice.

 The definition of Zero Net Carbon Building has three components, listed in order of priority: first, maximize energy efficiency of the building (through means like Passive House); second, maximize onsite renewable generation, as practical (through rooftop solar, for example); and third, make up the difference between building consumption and production through offsite green energy purchases.

 We’re teaming with NW Energy Coalition, the Seattle 2030 District, Sustainable Connections (Bellingham), the NW EcoBuilding Guild, the American Institute of Architects (Seattle), and the International Living Future Institute (South Sound Collaborative) to form the Zero Net Carbon Building Alliance (ZNCBA). See the ZNCBA statement of purpose and initial timeline here.

 ZNCBA will hold its first Member Meeting on October 17 in Seattle and is looking for input and participation from stakeholder groups including businesses, advocacy organizations, and communities. If you know a group that would like to receive a presentation or wants to inquire about membership, please contact Zack Semke at PHnw ([email protected]) or Chris van Daalen ([email protected]).
