Building facade has a significant impact in energy consumption since it is responsible for heat loss and over-heating. Thus, architects should consider not only the aesthetic criteria but also the comfort of users, environmental conditions, illuminance, glare and solar radiation when designing a facade. Today’s architecture seeks for a new approach for designing building facade that can adapt to changing environmental conditions and occupants’ needs. Kinetic facade systems can provide functionally efficient solutions since they play a key role to meet the aforementioned requirements. A kinetic facade can be described as a system that allows movement on the building surface in response to user needs and changing environmental conditions. This is a way of adaptation process of the kinetic facade.
The main objective of this study is to develop a new kinetic facade system that can adapt to ever changing conditions. For this purpose, first, a parametric model of the proposed kinetic façade is built. Then, the parametric model is used in simulations applying the “Multi-Objective Evolutionary Optimization” techniques to obtain optimal results for both the illuminance level inside the building and the solar radiation level on the facade. By this means, more efficient kinetic façade system is developed using the computational optimization which is another focus of the study. In this thesis, the kinetic façade is designed based on regular tessellation technique which has hexagonal shape. The proposed kinetic façade can be applied to all building facades facing any directions. Therefore, its flexibility and mobility provide functional, effective and efficient solutions for user comfort.
