Looking to buy or sell an energy efficient home that is on the path to zero energy or zero carbon? It is important to engage a real estate agent who understands the market value and the features of high performance homes, such as zero energy, zero energy ready, and passive homes. A real estate agent trained in energy efficient homes can help you identify whether or not the home you are considering is truly energy efficient or not, and they can help you evaluate whether a building lot you are considering buying has the appropriate exposure for constructing a zero energy home. They can also help identify banks and appraisers who understand the value of a truly sustainable home. Similarly they can help sellers of highly energy efficient homes get full value for the energy efficiency features and benefits they offer.
