Since most of the annual energy consumption in each country is related to the construction, optimization of energy consumption in buildings is important. When a single issue of energy is investigated, especially in residential buildings, design standard and specific rules could be seen that to achieve solutions for low energy consumption, help- ing. Of course, these rules depending on the occupation levels, receive heat, heat loss and building diversity of users are different and therefore are not easily standardized. In addition, a solution for a successful commercial or industrial building is not automatically to be used for other buildings. For example needs of heating, cooling and lighting and heat absorption capabilities of people, equipment, lighting and the sun should be in relation to building form, orientation, structure, pattern of occupation and environmental needs are assessed to ensure that all the points already are to appear on the general design decisions to be applied. So this article is trying to introduce the factors affecting energy consumption, the proposed solutions will be based on the lowest consumption in the construction, and eventually reached a sustainable design.
