Abstract

© 2021 by authors, all rights reserved.With the use of Perforated Solar Screen (PSS), solar gains are controlled, cooling loads are reduced, and comfort conditions can be achieved while using its energy efficiently. Nowadays, the use of PSS is increased, especially in large, glazed facades. The design of PSS needs to develop and optimize for the temperate humid climate. A new design proposal is presented by considering the basic principles in terms of providing solar control by PSS within the scope of the study. The optimization of the design proposal has been carried out in terms of solar radiation, Annual Sun Exposure (ASE), and View with the use of Rhinoceros/Grasshopper by considering the design variables (angle, perforation ratio, width, and distance, etc.) of the PSS. An optimum design proposal has been presented for the existing classroom (transparency ratio: 60%) on the southern facade. Thermal comfort and surface temperature have been calculated. Design proposals can be developed for the west and east facades by using the method of this study.
