As my knowledge and experience of sustainable building practices continues to grow, so does my sense of their overwhelming importance. I completed nine months of classwork, projects, and final exam to receive the Sustainable Building Advisor certification back in 2009. Much of what was then cutting-edge has now been written into Oregon's residential building code. Still, the process of guiding homeowners to make wise choices, and contractors to build in a way that successfully marries building science and existing conditions, remains a complex one. Over the years, I've done extensive coursework through Earth Advantage and other providers to stay abreast of emerging technologies and evolving best practices. BetterBuilt Northwest, Green Building Advisor, BuildingGreen, Inc., Building Science Corporation: all these organizations are important sources of information and advocacy. My goal, always, is to help homeowners make wise decisions in creating comfortable, healthy, resource-efficient homes.
