Abstarct: Today, more than 40% of the energy produced in the world is used in the construction industry. Therefore, the management of energy consumption in the design of buildings is on the agenda of designers, which leads to the reduction of operational and operational costs and can be used in the long term. Using renewable and clean energy is the best way to replace fossil fuels. Using passive systems as a non-mechanical method is an effective way to deal with energy wastage and reduce the destructive effects of buildings on the environment. A central courtyard is an open space in the center of, next to and around the building, utilized to create thermal comfort, especially in hot and dry climates and are commonly made in square or rectangular forms. The appropriate design of the courtyards helps provide sufficient sunlight and promotes the visual perception of the residents. while exchanging heat with the outside. The south direction of the courtyards creates summer and winter-specific parts, which would cause shading during the day, provide evaporative cooling and preserve the cool air. Atrium, as a static solar system, reduces heating energy consumption by providing heating in the cold season, but its excessive heat in the hot season leads to an increase in the cooling load. The Windchatcher as the most prominent element of architecture in hot climates, as well as a static cooling system, the Windchatcher provides natural ventilation and cooling in the building. Windchatcher do not work in the cold season, which is one of their shortcomings. The research hypothesis is baxsed on the fact that the combination of two static heating and cooling systems can provide a part of the building's required energy throughout the year. Therefore, turning the central courtyard into an atrium reduces the consumption of heating (during the heating period) and by using the Windchatcher (during the cooling period) during the part of the year when the air temperature is not comfortable. As the temperature rises, it is possible to reduce part of the cooling consumption. To test the hypothesis, Design Builder software was used to simulate the building. The findings of the research show: turning the central courtyard into an atrium can reduce heating consumption between 24%-31% and lighting consumption between 24%-52%. But the cooling consumption of the building increases 32%, which can be reduced by 27% by optimizing the atrium and using canopies and shades. Also, using the combination of atrium and Windchatcher and their simultaneous use will lead to a 22% reduction in building energy consumption (17% heating, 20% cooling and 50% lighting).
