Despite a crippling ice storm in Texas, work continues at the project house. Builder Bill Moore shows master carpenter Norm Abram how he's using old roof rafters to fashion the railing system and nosings for the new stair treads. In the kitchen, homeowner Michele Grieshaber has selected six different paint colors, and paint specialist Mike Branch explains why, due to low-VOCs, the new paint we're using will be less toxic to homeowners and workers. Outside, plumbing and heating expert Richard Trethewey lends a hand moving a 1200-gallon tank into place on the property, while rainwater harvester Blake West shows how the water will be collected from the metal roof with a series of gutters and PVC pipes, stored in the tank, and used later for irrigation. Richard visits West Texas to see how Texans are creating clean, renewable energy by harvesting the wind. Tile contractors Robbie & Bryan Hawkins install handmade tile made from 50% recycled-content on the master bathroom floor. Richard gets an update on the mechanicals from HVAC contractor Matt Romero who's installed a high efficiency two-stage air conditioning system with an electronic clean air filter.
