 Also, parallel to the global population growth, energy consumption and environmental issues become a global concern especially while the building sector is consuming the highest energy in the world and most of the energy is used for heating, ventilation and air condition systems.For these reasons, the buildings today are expected to achieve both energy efficient and environmental-friendly design by using renewable energy partly or completely instead of fossil energy for heating and cooling and solar energy that utilize solar radiation from the sun.In this direction, the integration of passive solar systems in buildings is one strategy for sustainable development and increasingly encouraged by international regulations.
