As a result, ZE builders focus on the attributes of a higher quality home, which provides the homeowner with a healthier, quieter, more comfortable, and more energy-efficient home. A key message is the ZE home provides peace of mind, as well as a hedge against future utility bills, as the home is built with better components and with higher construction quality. Overall, customers indicate a willingness to pay more for high-performing homes. A Parks Associates survey of US broadband households in 4Q 2017 found 80% of homeowners believe that having an energy-efficient home is important or very important, and at the end of 2018, 89% reported energy-saving actions. Parks Associates interviews with builders confirm that most customers will pay approximately 5% more for higher quality, high-efficiency ZE homes.
