Anything else you'd like to share?: EcoNest homes are elegant, hand-crafted homes that utilize natural building techniques including: timber framing, straw/clay walls, earth plastering and natural, non-toxic finishes throughout. These handcrafted buildings utilize holistic design ideals and turns them into reality. See Ontario's first EcoNest home! Timber Framing Bring the integrity of nature into your home. Using time honored building methods, solid wood timbers are hand-crafted and pegged together. Completely exposed on the interior, the elegant wooden framework conveys a very real sense of structure, permanence and beauty. For centuries, timber frame homes have been passed on with pride, from generation to generation. Vapour Permeable Walls Straw/clay walls have been used in Europe for centuries. The EcoNest innovation is simple: utilizing the same time tested materials, but creating a 12” thick curtain wall which wraps the timber framed structure with a monolithic envelope with no thermal bridging. These light straw/clay walls are a unique combination of insulation and thermal mass, keeping the interior cozy and warm in winter and delightfully cool in summer. The insulative qualities “resist” heat transfer very effectively, while the mass allows for thermal lag which can offset peak heating and cooling periods. In conventional construction, a 6 mil poly wrap is applied toward the interior side of an exterior wall (in our climate). This wrap typically serves two functions; the first function is as an air barrier, and the second is as a vapour diffusion retarder (a.k.a. vapour barrier). This coupling of function leads to much confusion as to the role of these petro chemical 'wonders'. Make no mistake; the air barrier is essential for energy efficiency. And in an EcoNest or other natural homes, this air barrier is provided with careful detailing of a vapour permeable plaster such as earth or lime based plasters (NOT cement based stuccos!). The vapour diffusion retarder is aptly named as it very often prevents drying of structural or insulative elements within exterior wall cavities. As they are often installed by some of the lowest paid members of the crew, the attention to detail is often non-existent, and as such, small spaces or gaps occur. Because the poly also acts as an air barrier, the pressure differentials force very large quantities of moisture through these small openings, where it is then deposited within the wall cavity. Because the vapor barrier interferes with the drying of these materials, the safe “moisture storage capability” of the materials is often exceeded. In other words they stay wet for long enough that rot sets in (as well as mould and mildew). In the long winter months of Canada, this also means that our first line of defence in flu season, namely our mucus membranes, are often dried out and desiccated by forced air central heating systems combined with vapour barriers which retard the addition of moisture to the indoor environment. But why all of this fuss over moisture? What if my drugs of choice are acetaminophen, codeine, and caffeine (over the counter flu medicine)? Two words: building longevity. It takes a lot of money, and energy (embodied and otherwise) to build. If you are going to build, the best value financially and environmentally is to prorate those expenses over a number of years say… 500 to a 1000 years! This is the known lifespan of structures built with similar materials in Europe, and there is every reason to believe that an EcoNest home, coupled with a structural timber frame, will last just as long! Now it starts to make sense to pass-on the structure to a family member, which in turn flies in the face of the whole notion of “starter home-dream home-retirement home- funeral home”. One home can do the job of four, while costing the same as a conventional one! Earth Plastering Light straw/clay walls are ideally suited to plaster because they are perfectly flat but coarse in texture so that the plasters adhere to them without needing lathing. Earth plastered walls are both durable and beautiful. Rich in possibilities of color and texture, these walls exude a vibrancy found only in nature. The EcoNest Company Located in Tesuque, New Mexico (near Santa Fe), the EcoNest Company was founded by Robert Laporte and Paula Baker-Laporte. Robert Laporte is a timber framer and natural house building pioneer and teacher. Paula Baker-Laporte is an architect, baubiologist and author specializing in healthy and ecological design. Since 1994, Robert and Paula have been co-creating EcoNests - homes which embody the principles of sustainable building, health and beauty. Joshua Thornton, the sole Ontario representative of the company, designs and builds the frames. He has also conducted research for the Canada Mortgage and Housing Corporation on the material properties of straw and clay, and is also a workshop facilitator, public speaker, and lifelong student of making things.
