That's all there is to it: the Green Building Slam. A simple idea, started years ago, has transformed into one of the most fun and inspirational green building events of the year. Learn about 10 innovative, sustainable, high-performance "green" buildings that push the envelope in our built environment. Projects range from residential to multi-family to mixed use developments in the Seattle area. 

Each of our juried 10 presenters will have just 10 minutes to show us 10 slides of their exciting project as they explain what they learned, what they would do differently, and any other sustainable contributions that their project has made to our local community. Each presenter is an active member of the NW EcoBuilding Guild, has been trained by a speech coach, and is excited to share their project with the masses. Don't miss this night to remember!

Our audience typically attracts architects, builders, homeowners, energy efficiency experts, real estate professionals, interior designers and fabulous, eco-conscious people like you. This year we are expecting a SOLD OUT event to a packed house of 400+ guests.

After discovering Passive House in 2009, the comprehensive nature of the concept redefined how I and many others conceive of and deliver buildings. Now, after a decade, I have delivered many Passive House projects and have learned countless lessons. This presentation will be a quick look at 10 key projects built in the Puget Sound region starting in 2009 and concluding in 2019. From experimental to standard practice, from single-family to 45-unit apartments, the styles are wide, the lessons varied and the results are inspiring. We can deliver terrific buildings which deliver healthy, beautiful and durable spaces, all with reduced environmental impact, this is my story of pursuing that goal across the decade.

Having met in California, when these homeowners moved to Seattle, they hoped to bring the ease of indoor/outdoor California living with them to the Pacific Northwest. After purchasing a modest, post-war home in which to put down their new Seattle roots, their original intent was to build up with a traditionally-styled second story addition. However, as we explored early design concepts, they realized a mid-century inspired design aesthetic suited them better. As that and other major changes began to pile up — such as wanting to raise the ceiling height of the existing first floor by two feet — we realized, rather than a second story addition, the solution was to build a new home on the existing foundation. Not every client comes in for a remodel and leaves with a new home. But, by taking this house back to its foundation, we were able to nestle a sustainably-minded, mid-century-inspired design into an established Pacific Northwest neighborhood in a way that feels like “home” to these California transplants.

Nearly four years ago I decided to solo build my own custom net zero home and write about the experience in a blog.  I left my job in September, 2015 and joined my cousin, an experienced and innovative contractor, who as luck would have it was just starting to build a home for his daughter.  I learned about advanced framing, thermal bridging, energy recovery ventilation, heat pumps, energy heels, solar heat gain coefficients, and Joe Lstiburek’s perfect wall, and so much more. After nine months, I decided I was ready to set out and build a house of my own. My story covers my journey from living with no utilities to enjoying one of the most efficient, high standard green homes in town.

SOLO BUILDING A NET ZERO HOME (with Limited Experience)

Thirty years ago, architect Kim Pham attended the wedding of dear friends, Molly and Parker. Knowing his design skills, Molly asked him to assemble the wedding cake. This collaboration was the first of their friendship, but not the last. Kim designed their first home and a number of additions to the house as the family grew. When the opportunity arose for the family to build a new home, their choice of architect was clear.  Kim assembled a Stuart Silk Architects team of project manager, staff designer and interior designer. Each brought their own set of strengths to the table including organization, graphic/modeling skills and green building knowledge. During construction the team expanded adding general contractors and site supervisors from McMeekin Construction. Molly was fully engaged in the entire process, visiting the site several times a day. The collaboration amongst this group was truly unique, the symbolic foundation of the home.

What began with a friendship between Kim, Molly, and Parker expanded to embrace the rest of the design/construction team along with the surrounding environment. Unity was the key to the project’s success.

A modernized small home that was originally built as a carriage house. Heated floors, a woodworking nook, a place for the band to practice, plus a spiral staircase and the clients were able to make their mark with salvaged and repurposed beams as unique, featured flooring. That’s just the beginning...  This Lake Washington carriage house needed more functional living space, more natural light, and a whole new heating system for both levels of the home, and separate spaces for hobbies and interests. Results: The awkward and unlivable basement was transformed into an additional floor of conditioned living space that meets the client’s needs. Even though a majority of work was completed in the basement, the addition of livable square footage allowed them to rethink the use of space on the main level. Our clients also put their own stamp on the project by completing some of the more intriguing finishes themselves.

The Roost, a 33-unit artist live-work community, is an embodiment of our commitment to create livable housing that integrates affordability, community, sustainability, and access to housing for all. Neiman Taber specializes in the design of microhousing as a way for market-rate development to help address Seattle’s challenges with affordability and housing supply. To fully realize this goal, we stepped beyond our typical role as architect and took on the responsibility of project development. By developing and operating The Roost, we were able to pursue a holistic program that combines small private apartments, communal living areas, and cultural space that supports the arts, while significantly improving on code standards for building performance.

Selah Vista (SV) Homes, the first planned Neighborhood Development in Central Washington, is inspired by the belief that everyone deserves to live in a healthy, energy-efficient sustainable home. Creating spec homes for this 60-lot Net Zero PUD that met all the goals within a reasonable budget provided many challenges and opportunities. It was developed by Steve Weise and supported by the integrated team at Leading Force Energy and Design Center in Yakima. The model home was constructed in 2018 and is the focus of this presentation.

The SV model home is a tool for educating building professionals, realtors and residents about a better way to live. Proving this concept, the model home swept its category at the 2018 CWHB Tour of Homes, winning five awards including Best in Class and People’s Choice. It also won the prestigious U.S. Department of Energy 2018 Housing Innovation Award, Custom Spec Category.

The Pacific Northwest is going through a significant growth period. This places a significant burden on our built (and unbuilt) environment as the need for housing and rental space seems ever-expanding. [bundle] design studio, our small architectural design firm based in Bellingham Washington, is going through an analogous process. Between 2017 to 2018 our team increased from one to three, and the current home office no longer meets our needs. With lofty goals which didn’t match our budget, a solution began crystalizing when we acquired a salvaged RV trailer frame from local tribal non-profits. By building and working in a mobile tiny office, our space would double as a highly tangible, healthy, and beautiful teaching tool for clients and the local community seeking alternative solutions to housing and rental space shortages. If we succeed in certifying as PHIUS+ Source Zero, the [bundle] Tiny Office will be the first building of this type
to do so. We look forward to sharing our journey with the Northwest Ecobuilding Guild and all who are curious to know more.

Tiny Footprint, Big Impact

Most current land use policy continues fossil-fuel dependent patterns of segregated uses at very low density.  It is not enough to mandate or build high performance green buildings, if they are dispersed through an unsustainable land use pattern. Either we’re baking in dependencies that drive climate change or we are remaking the pattern to reduce it.

We all must evolve and embrace a more compact and sustainable ways of living, by putting people where jobs, parks, transit, and in neighborhoods already exist. To do that, it is critical we embrace ‘Green Zoning’-- incremental increases in infill development that can lead to big reductions in carbon emissions. As architects and building professionals, we can be key communicators to scale up regional efforts and make our neighborhoods, towns and cities catalysts against climate change.
