This episode is set at a stylish Sudbury, Mass., home designed by its owner and built out of industrial-grade insulated steel panels. Host Kevin O'Connor goes to a "deep energy retrofit" project in Medford, Mass., where a century-old two-family house is being transformed into a high-performance, low-energy powerhouse. In Portland, Maine, licensed contractor and host Amy Matthews helps put up a building made entirely with ThermaSteel structural panels, a product now available at home centers, in just one day. In Newton, Mass., Kevin talks to Boston Globe tech reporter Hiawatha Bray about the many new options in video on demand. Amy meets "tiny house" pioneer Jay Shafer at his facility in Sebastopol, Calif., to see what life is like being in a building as small as 65 square feet.
