Global warming, Ozone depletion, increasing levels of the environmental pollution and species extinction and irreversible environmental changes caused by human, and environmental issues for the futureinevitable. Speaking of sustainability in architecture can be interpreted as thought of designing,manufacturing and future structures. Not only by the physical stability of the building, but also by the stability and maintaining of the structure and its energy resources. Thus, it seems thatsustainability of a model can be conceived on the basis which we use available resources moreefficiently before we waste or ignore them. This style of architecture is one of the modern trends of the architecture which is in harmony with the natural environment, which is One of the basichuman needs in today's industrial world. In general This attitude is to prevent the destruction of nature and providing environmental protection, and paying attention to the future generations. The efficient use of energy and using recycled materials in the construction of the local andcultural aspects is the original concept of using ecology in the architecture that has been expanded in the past two decades. In short order the definition of the ecology of the building is based on the focusing on the building capability to integrate environmental and atmosphericfactors and converts them into the quality and comfort of the space. This has led the researchers to provide other types of energy (renewable, clean energy) to replace fossil energy.
