A “Net-Zero Energy Attainable” home is designed to potentially produce as much electricity as it uses by means of a solar PV system (photo-voltaic panels). The homes are all electric, super insulated, air tight and are equipped with a makeup air system. Lighting is LED or CFL. All appliances are Energy Star rated. HVAC is by Mitsubishi electric heat pumps. With a reasonable lifestyle, your family can live comfortably with little if any energy cost.
