Mitigating Water and Heat on the Façade Creatively Through Textile Materials: HydroSKIN
Session: G: Innovation Award
Architect & Researcher, University of Stuttgart, Institute for Lightweight Structures and Conceptual Design
The implementation of textile materials in the building skin opens up a revolutionary new spectrum of functionalities in the façade. Apart from a significant weight reduction of the entire high-rise building, the use of textiles as a retention surface in the façade enables the absorption, targeted use and time-delayed release of precipitation water to reduce flood and heat risks. Thus addressing the rising climatic impacts of urban architecture: Urban “Heat Islands" as well as floodings with considerable personal and material injury caused by heavy rain events will constantly increase due to global warming and the rising amount of sealed surfaces.
Essential part of the HydroSKIN is an external, multi-layered 3D-textile acting as a collector and evaporator. The hydroactive textile element to be modularly implemented in both new and existing buildings reduces the impacts on urban sewage systems as well as heat loads by evaporative cooling of environment and building. In combination with further adaptive components for interior conditioning, the use of HydroSKIN significantly increases user comfort while simultaneously reducing water, material and energy consumption of high-rise buildings.
