Two years ago, the Asani/PHC team of architects, builders and developers set out to design a Net Zero energy home using local and sustainable materials, all with a construction budget under $150/square foot. These homes are part of the new One Planet Community (one of 8 in the world) on Bainbridge Island – a Zero Carbon neighborhood of homes that is affordable to young families and baby boomers alike.
The new homes at Grow Community are not just net zero energy homes, they are part of a neighborhood where residents will be able to reduce their overall carbon footprint – that is, the impact from buildings, transportation, and food to name a few. The homes are part of a One Planet Neighborhood, homes where it is easy, fun and affordable to live a lifestyle where our impact on the planet is a little lighter.
One Planet is a framework to guide design of Zero Carbon neighborhoods. The program focuses not just on environmental impacts, but also on economic and social sustainability, creating communities where neighbors interact and where ecological footprints are reduced. Grow Community has used the ten sustainability principles of the One Planet framework to create a neighborhood that is unlike any other in the United States.
The homes are beautifully designed, light filled spaces located in small clusters with the community, all surrounding vegetable gardens. The neighborhood is made up of equal numbers of single-family homes for sale and multifamily homes for rent, providing different financial options for residents to live in the community. The floorplans are designed for families, for couples, for aging in place, a mix that has resulted in a truly intergenerational community.
When we first started to design the Grow home, we weren’t sure if we could meet the net zero challenge with the given budge, but with a little determination and a dedicated team, we’ve shown it can be done. Each home and multifamily building is designed as a Net Zero home – the solar panels on the roof are enough to provide all the power needed throughout the year. The cost of construction of each of the homes is both reasonable and replicable.
The One Planet framework was used to balance design and material choices against each of the sustainability principles. We designed an energy efficient building envelope, using local and sustainable materials wherever possible, and choose finishes that would ultimately create a comfortable and healthy home.
Health and Happiness is the foremost One Planet principle driving design decisions both for the individual homes and for the community as a whole. Each house is built using the highest quality materials to create a healthy indoor living environment, including:
• Marvin Integrity word/fiberglass windows avoid the use of PVC in the homes;
• Cork or local sustainably harvested wood floors with non-toxic finishes create local and healthy flooring options;
• Silent and highly efficient mini-split heat pumps to maintain comfortable temperatures;
• Cabinets with no added formaldehyde, recycled content countertops and induction cooktops for sustainable and well-appointed kitchens; and
• Optional whole house water filters.
The community itself is designed around numerous vegetable gardens, with native plants and vegetation throughout to create natural and inviting places for children and adults to enjoy. The neighborhood is located just a short walk from urban amenities, enabling residents to walk or ride, incorporating exercise into their daily lives. A community center will provide a space for yoga classes, cooking demonstrations, and community events.
It is our home that this One Planet neighborhood will change the way we approach urban design. We created the project to demonstrate how developers might design projects that have a net positive impact, not only on the environment, but on the way people live, creating healthier and more satisfying lifestyles in urban areas. The Grow Community homes are not just good for the environment, they are a place for people to live healthy and affordable lives, to connect with their neighbors, their community and nature.
