It all starts with a holistic approach from the ground up with the aim to first, reduce our home energy consumption by installing high performance building envelope, including but not limited to double glazed windows with low emissivity, better insulation that exceeds minimum building energy code, use of high efficiency appliances and HVAC equipment. And second, install solar electric (PV) and thermal systems to handle the remaining annual energy requirement. High performance building envelope combined with high efficiency appliances and equipment, and integration of solar energy systems can lead our homes to become NZEB. A case study is discussed.
