Optimization Of Office Building Façade To Enhance Daylighting, Thermal Comfort And Energy Use Intensity

Mahmoud Gadelhak, Werner Lang

Abstract: The aim of this paper is to examine a framework in which an office building façade was optimized for the integrated performance of total energy consumption, daylight quality and thermal comfort. A south facing façade of an office space was modelled parametrically for two case studies in Cairo and Munich. The effect of changing the window dimensions, glazing system, insulation thickness, as well as different shading and daylighting systems was analysed using Radiance and EnergyPlus simulation tools. A multi-objective optimization was performed to reach an optimal range of solutions. The results from each case study and the relations between the design variables and objectives for each case were studied. Moreover, the practicality of using a simulation-based multi-objective optimization in generating high-performance design alternatives was examined. The results show that the use of multi-objective optimization for complicated design problems can aid in reaching performative solution and clarify the relations between the design variables and objectives.
