There are about 125 million existing homes in the U.S. representing the most significant and yet challenging opportunities to save energy and reduce our carbon footprint. But how do we approach green remodeling differently than new construction? This course, led by green building expert Peter Yost, will use the web-based tool, GreenBuildingAdvisor.com, to make the comprehensive case for green remodeling. This will be a “soup-to-nuts” approach to green remodeling, covering all of the essential principles of building science on projects ranging from weatherization to gut rehab to deep energy retrofits. Day 1 will focus on green remodeling principles and the tools available to employ them. Day 2 will be driven by case studies (including the 8-year deep energy retrofit of Peter’s own 100-year old home) and YOUR projects!
