The concept of net zero energy buildings has recently taken a great attention in future building. Energy conservation and efficiency techniques must be completely utilized in order to attain a zero energy balance on an annual basis. However, in most building and under most climatic situations, there will be a necessity for active heating and/or cooling as well as the electricity demand. Solar energy is the most common renewable energy source, and it may be used to fulfill a large portion of the energy demand in buildings. Heating and/or cooling are the primary energy demands in buildings, depending on local climatic conditions and building form. In this paper, we look at some of the most effective strategies to meet a portion of the demand for heating, cooling, power generation for residential building. This study presents three possible alternative technologies for supplying the needed cooling and heating loads of 27.26 kW and 9 kW, respectively. This parametric study will result in energy savings of more than 80% for cooling and heating systems. It is found that the payback period for solar electricity system by PV is around 7.5 years.
