2021 Built Green Conference and Hammer Awards in Review

After a year of meeting virtually, we would like to extend a huge thank you to those who attended the in-person Built Green Conference that took place on September 16th at the Lynwood Convention Center. The day was filled with reunions, networking, and captivating sessions tackling everything from building science to policy to increasing inclusivity in our industry and communities.

2021 Built Green Conference session

Throughout the day the year’s theme “Equitable Futures” was embraced by our speakers. The concepts of equity, adaptability, resiliency, and innovation were integrated across sessions that covered policies to retrofit and remodel existing building stock to reduce carbon emissions, field practices to promote cost-effective material and full-house salvaging and reuse, best practices to increase community engagement and support for inclusive communities, creating spaces and company culture that are conducive to a diverse workforce, and technical knowledge to design and build homes that can adapt to a changing climate.

Keynote Sam Rashkin

Our morning keynote Sam Rashkin of Retooling the U.S. Housing began the day by defining the future of housing through solution-based innovations to tackle the five crises impacting builders today. Rashkin challenged us all, “to address pain points related to user experience readiness, housing affordability, trade availability, productivity and digitization in our industry”. As one of the most fragmented industries, our producers, products, research, and innovation for problem solving is often too narrowly focused. Rashkin argues for “connecting the dots” through integrated innovations such as user experience optimizations, design optimization, mass-customization in building practices, and digitizing practices through emerging SaaS Data Aggregation. We recommend checking out Sam Rashkin’s forthcoming book Housing 2.0: A Disruption Survival Guide for more information surrounding these concepts and more!


Following our keynote address, conference goers had the opportunity to attend sessions from four different tracks: The Future is Here, Reduce, Reuse, Recycle, Equitable Transitions, and Resilient Structures. The sessions topics ranged from addressing how community engagement can inform design processes, examining the carbon accounting benefits of moving a house, implementable material salvaging and reuse, concepts driving Washington State Energy Code (WSEC-R) forward and a multi-sector panels discussing the policies and programs needed to address emissions from existing buildings.

Session Highlights and Take-Aways


Grace Kim, Schemata Workshop, Donald King, Mimar Studio, and Brian Runberg, Runberg Architecture Group, described the extensive effort they took to engage with Seattle’s Central District community on the 23rd and Jackson project. Over the course of 2 years and over 100 meetings with community members they delivered a multifamily mixed-use development, that included affordable housing units and small business incubator spaces, that was whole-heartedly supported by the community and seen as a community asset. From the start they approached the community with humbleness and no predetermined designs, using instead a call-and-response design process with community members. This collaborative process, while time-consuming, helped to built active engagement by community members that in turn smoothed the design board review process and reduced costly redesigns.

“We can’t stop gentrification, but we can look at how we can be more inclusive in our development and design.” – Donald King


2021 Built Green Conference session

Jeff McCord with House to Home explained embodied carbon accounting benefits of moving a house for another century of use through a triaged approach: rehab, repurpose, move, and salvage. Jeff McCord explained how 20% to 40% of landfill space is taken by construction and demolition debris. McCord stated that “moving a house, when possible, is one of the single greatest ways the embodied carbon from that house and waste generated from construction and demolition can be saved.”

Dan Wildenhaus of BetterBuilt NW and Poppy Storm of 2050 Institute explained how we are currently witnessing a market transformation imperative. Wildenhaus explained that by “2035 every new thing that goes into a new building, or existing one, will need to be high efficiency and electric”. Poppy furthered that “by 2030 we have to achieve emissions below that of 1990, and then by 2050 we must be carbon neutral. This is a tall order with a tight timeline that will require innovations in streamlining equipment and envelope design.”

Greg Davenport with Mitsubishi Electric had the opportunity to present the South Perry Blockhouse Life Project in Spokane that includes many green building features and innovations; such as cross laminated timber, solar power production, off-site building customization, and high-density, transit oriented designs.

Karen Dove, ANEW, Jay Pershing, WELD Seattle, and Sarah Smith, Sawhorse Revolution, each work in different ways to develop more inclusivity and representation within the building and construction industries. The largest challenge faced by the individuals they work with are barriers created by detrimental workplace culture once they enter the industry. Karen recalled one firm she worked with that hired five women trades people - and due to the poor workplace culture and harassment they experienced - once their apprenticeship ended they left the industry, at a replacement cost of $200,000. Shifting the culture in a company to view inclusivity as an issue of safety and productivity is critical to being successful in recruiting and retaining a diverse workforce.

With Covid vaccination being required for all attendees, and plenty of room to accommodate social distancing, throughout the day our community was once again able to come together to share ideas and catch up with friends. Even with masks in place we could see all the smiling eyes and hear the joy in people’s voices as they were able to connect in a way that cannot be replicated over a computer screen.
