Evolutionary Optimization of Building Envelope Design with Photovoltaics-Integrated Shading Devices

Abstract: During performance-based architectural design, faćade elements that have an influence on performance need to be integrally considered. This study addresses the need to support building envelope design, and specifically the design of photovoltaics-installed shading devices. Photovoltaics-installed shading devices simultaneously influence various performance criteria such as building energy consumption, daylighting and electricity production. Therefore, their design needs the support of optimization tools that help evaluate different design alternatives based on these performance criteria. This paper presents an evolutionary optimization approach that is extended from a model developed previously by the author, which optimizes multiple performance objectives towards the search for optimal envelope configurations. The tool is tested on a number of building forms with different photovoltaics-integrated shading devices, and a comparative evaluation is presented. The results show that genetic optimisation can provide meaningful insight to the problem towards well-informed decisions being taken.
