Abstract
The courtyard is an architectural element found in hot arid regions due to its thermal performance that gives it cooler temperatures than the outside resulting from shading and night cooling. Previous papers focus only on either shading or ventilation and never together. This paper employs CFD techniques to simulate heat transfer in the courtyard. The results are presented through time constants showing the response of the thermal mass of the building containing the courtyard toward solar radiation and night cooling and the effect of both being combined in a factor called the Night-Time Effectiveness Ratio (NTER). The research includes simulation for different courtyard sizes and other building elements around the courtyard, like galleries. The results show the importance of the courtyard's width in changing the performance of night ventilation. Adding extra shading elements such as galleries can enhance thermal performance by 30% - 60%.
