A New Design Proposal for Perforated Solar Screens and Optimization in terms of Solar Control

Abstract

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.

Parametric Hypercell Mechanism for Adaptive Building Skin: A Case Study in New Administrative Capital, Egypt

“…Therefore, the concept of adaptive building skin appeared. Adaptive building skin can be interpreted as an envelope that can change its features and flexibly manage the building envelope's different parameters [2]. Change can be achieved in several ways, including by movement or chemical change in building materials [3].…”
