Sources of energy are the most important challenges facing the world in this century. The global interest in energy and its relation to the construction sector that consider the most energy consuming sectors, which led to a search for methods of energy conservation. Research assumes a methodology to apply the modern technology in buildings and gaining advantages of developed building materials, outer envelopes, and conserve energy systems to reduce energy waste and increase its efficiency by integrating natural and renewable energy applications. This methodology could be applied to buildings during the design phase to achieve energy rationalization.
