We are currently doing a deep-energy retrofit full renovation and addition on a single family home in the beaches area. We are working with Terrell Wong, architect from Stone’s Throw Design, structural engineer Tim Krahn from Building Alternatives, and mechanical engineer Stewart Fix from ReNü Building Science. The addition will be insulated with straw bales. We will strive to meet passive house air tightness standards and we will use FSC certified lumber and wood products and more environmentally choices for adhesives and sealants. The project includes passive house windows. Many of our green building supplies come from Eco-Building Resource.
