This thesis explores a new climate-responsive building model that utilizes the inherent responsiveness of hygroscopic materials and the instability associated with moisture content to construct a bionic adaptive building skin. The skin expands and contracts in response to changes in humidity in the weather, resulting in dynamic and responsive building elements. Climate response in architectural elements is generally considered a technical function achieved by mechanical and electronic sensing, driving, and regulating devices. However, the facade system requires neither additional mechanical nor electronic control nor an external energy supply to adapt to the precise perception of environmental fluctuations. In contrast to this overlaying of high-tech equipment on otherwise inert materials, the thesis uses a bionic design strategy: the hygroscopic behavior of spruce cones moves their scales in response to a humidity gradient. Therefore, the physical programming calculation and simulation of maple wood veneer material were carried out to express the plant behavior to realize the active mitigation of the influence of climate conditions on the indoor environment of the building and timely response to the temperature and humidity changes of the external climate conditions. Overall, the thesis proposes an innovative approach to adaptive architecture that combines bionics and hygroscopic design principles to create responsive and dynamic building surfaces to increase energy efficiency, improve indoor air quality, and create more comfortable and sustainable living spaces.
