Population growth, finishing and wasting the energy sources, the contamination from the fossil fuels and finally the corruption in the environment are the factors which are alarming the limits the future of the human beings and also the underlying dangers. Considering the existing limits the only correct way is the right use of energy, optimization in the energy consuming appliances and using new returnable sources of energy in order to control the energy crisis. So using the new sources of energy instead of fossil fuels is obligatory. So the new sources of energy should rely on structural and fundamental changes in which the solar energy is used in them and using this source of energy is a based in this type of construction and sustainable architecture which can solve many of present problems of society in optimizing energy consumption. In this article we have worked on solar energy as a returnable source of energy in buildings and the relevant effects on energy consumption reduction and the effects on architecture stability.
