In the past, human depends in a ventilation and light on the methods and natural Energy In modern buildings became the use of air conditioners is prevalent and is an example of an important control of modern man in the internal climate of the building, and with the danger of depletion of conventional energy resulting from wasteful consumption and increased human activity sources, addition to environmental pollution resulting from the excessive use of fossil fuels such as oil, coal and natural gas, leading to study the energy-saving buildings as a means to reduce loads and also to reduce the use of mechanical methods in cooling and heating to the rationalization of energy use, by using the energy from natural and renewable resources, such as sunlight and wind that help to reduce the energy crisis and pollution reduction.
In this framework, the research mention to study the several entrances to control the use of renewable energy in buildings, which suit urban areas in Egypt as an input for the development of the construction of housing, and highlight the role of its contribution not only in savings energy but also in the variety sources of production inside the building, making the buildings producing energy and for those who around them sometimes, in order to achieve the goal of the economy in a reducing the cost and operation of housing facilities,
