Using Parametric Design To Optimize Building’s Façade Skin To Improve Indoor Daylighting Performance

Abstract: This paper presents a performance oriented parametric approach for a façade's skin design to enhance indoor daylight quality. This approach utilizes daylight performance evaluation to search for skin design that improves the distribution of the daylight indoors by achieving the requirements of daylight metrics of both Leadership in Energy and Environmental Design (LEED V4) and Illuminating Engineering Society (IES) in early design stages. Parametric design procedure is proposed and consists of four integrated phases: (1) generate the skin, (2) analyse the skin's daylight performance, (3) evaluate the daylight performance and (4) search for the near optimum solution. "Genetic Algorithms" and "Exhaustive Search" as two different search and optimization techniques where implemented to understand the potentials of each one to be integrated in the proposed procedure in the forth phase. The study outlines the challenges and opportunities opened to architects to apply the proposed procedure to integrate daylight performance evaluation in early design stages where the most influential design decisions are taken.
