The Home is sited on an East West axis to allow passive solar gain as well at aligning the roof for both Solar thermal and a PV system. The client installed ALL LED light except the oven. And that only because they could not find one designed for the oven heat. All appliances are Energy Star. A 12 KW PV system was installed. Ashland Oregon is unique in that they have their own electric utility and will buy back all the Solar power you do not use. This system gives the home 10-Watts per Square Foot. The client installed a rain water catchment system in the backyard to use for irrigating their garden and a grey water system to water the plants in the front yard. The windows were U.30 and the insulation in the inner wall is denspack R-4 per inch.
