Now a day’s consequences such as increasing air pollution and environmental contamination, reduction in natural resources and energy crisis which are due to the present industrial life, has made the human being to regard conservation of natural resources as the most important issue at the present time. Green architecture plays an important role in this regard by improvement in building efficiency, saving the energy, putting steps toward using new types of energy and all in all being in the same direction with the nature. Considering that 50% of energy consumption is done in buildings the idea of the Zero energy buildings is created to provide the energy needs in the 21st century. In the ZEB using the highest renewable technologies the balance between the amount of the produced energy and consumed energy is achieved. In this paper we tend to study the basics of construction of such buildings.

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.
