In a time of energy crisis and growing population, the limited resources and increasing emission and global warming have effected in the world, so the developed countries have set policies, legislations, goals and roadmaps to reduce their environmental impacts and their energy demand. To be more precise, they have decided to drive the human society to sustainability, to save their planet and their race and also to maintain a sustainable safe supply and an energy sustainable society.For a higher efficiency achievement in energy systems the role of buildings are more emphasized. Therefore, they have chosen passive houses which are construction that is worked with green energy or renewable energy. These buildings are covering energy saving of consumers, more energy efficient production and substitution of fossil energy with renewable resources and development of renewable fuel technologies to cover the energy demand. In this article, we offer to use solar heating systems in passive houses that are supplied a part of tap hot water and heating. We choose solar energy because is free and very environmental friendly; however it may be combined to another energy system as a backup
