Özet:

The use of adaptive building envelopes creates an essential potential for reducing carbon emissions and energy consumption. However, most existing adaptive façades are made up of rigid body mechanisms, which require multiple actuators to initiate the movement. These mechanisms can lead to limit the applicability of adaptive building envelopes in the construction industry due to the large number of required actuators. To address this issue, developed with the knowledge of biomimetics, the curved line folding (CLF) technique offers an alternative design method that relies on compliant mechanisms rather than rigid body hinges. In this context, by using flexible elements to allow for elastic deformation, CLF can reduce the complexity and number of actuators required to initiate movement by discovering biomimetic knowledge. Therefore, the thesis aims to propose a novel strategy, further research questions, and recommendations based on the CLF technique comprehending biomimetics. Furthermore, it is intended to present a proposal integrating cables to offer a novel actuation strategy since CLF systems have not been addressed yet with cable-driven systems. In this thesis, firstly, the literature that comprehends existing biomimetic approaches and architectural examples in adaptive architecture and compliant mechanisms is examined. After the experiments on the type of systems, such as active and passive approaches, the case study has been carried out. The study presents an innovative façade model that reduces the number of actuators and complexity while initiating the movement of the systems based on CLF. Then, the case study is prototyped via handcrafted and digital fabrication techniques with 3D printers. As well as the digital modeling of the adaptive façade in the Rhinoceros environment, daylight simulation of the proposed system is run with the use of ClimateStudio software to vi compare the effects of the adjustable façade. This research may contribute to revealing further research questions, methods, and recommendations regarding the usage of compliant mechanisms in adaptive building envelopes.
