    One of the key principles of high-performance, zero-energy homes is reducing energy use to a minimum. Since space heating and cooling have traditionally been the biggest residential end uses of energy, there is considerable emphasis on building insulation and air sealing. In most climates, it’s less expensive to increase wall insulation than it is to install a ground-source heat pumpHome heating and cooling system that relies on the mass of the earth as the heat source and heat sink. Temperatures underground are relatively constant. Using a ground-source heat pump, heat from fluid circulated through an underground loop is transferred to and/or from the home through a heat exchanger. The energy performance of ground-source heat pumps is usually better than that of air-source heat pumps; ground-source heat pumps also perform better over a wider range of above-ground temperatures. or more solar panels. For this reason, the walls of zero energy homes in heating-dominated climates usually require something thicker than 2×6 framing.
