When Ed and Rachelle asked for a LEED platinum house, contractor Scott Harris (On Begley Street) couldn't resist the challenge. Even without much knowledge of sustainable homes, he seized the opportunity and studied up on the features that would set this super eco-friendly house apart from the norm. But don't worry, you don't have to be Ed Begley Jr. with pot fillers, Lutron lighting, and a greywater system if you want a house with a low carbon footprint. Scott shares budget-friendly ways to make your own house better for the environment, and take care of your own health by preventing mold from infiltrating your walls.
