Proposal for a Kinetic Façade System Based on Curved Line Folding Technique

Abstract

The use of kinetic building envelopes creates an important potential for reducing carbon emissions and electricity consumption. However, a number of existing kinetic fa & ccedil;ades are made up of rigid body mechanisms, which require multiple actuators to move. This limits their feasibility in the construction industry due to the large number of required actuators. To address this issue, the curved line folding (CLF) technique offers an alternative design method that relies on compliant mechanisms rather than rigid body hinges. By using flexible elements to allow for elastic deformation, CLF reduces the complexity and number of actuators required to initiate movement. On the other hand, cable-driven systems have not been explored to actuate the CLF mechanisms. This paper aims to investigate an innovative fa & ccedil;ade model that reduces the number of actuators and complexity while initiating the movement of the systems based on the CLF technique and cable bending system. In this paper, firstly, the existing literature is examined. Then, the proposed kinetic fa & ccedil;ade system, its geometric properties, and actuation is introduced. Finally, a daylight simulation of the proposed system is run in Rhinoceros with the use of ClimateStudio.
