As energy consumption has become a serious concern, energy efficiency is emerging more of a priority in recent years. As a result, there has been a general movement towards finding effective design strategies to lower the energy demands of buildings and to encourage further awareness of energy-conscious design. Passive solar building design can result in higher requirements than a conventional building; however those systems can reduce the auxiliary heating costs in buildings, without compromising occupant comfort. The courtyard as a passive solar system was developed mainly in response to climatic requirements. Poor or inappropriate design may create challenges for controlling temperature, glare, and energy consumption in courtyard. For this reason, based on literature review this paper investigates energy efficient courtyard design with respect to shape, ventilation and performance of the courtyards in terms of daylight factor, so that, energy efficacy performance of the building can be improved. Thus, it is expected; findings of this study encourage building designers and decision makers to be carefully considered in the design phase of building in terms of environmental concerns and energy efficient building design.
