Scientists have proposed to reduce flooding and urban heat by using a textile shell on facades.
Young scientists from the University of Stuttgart presented the HydroSKIN prototype. The lightweight textile shell absorbs rainwater that falls on the facade. It can then be used to reduce water consumption inside the building, for example, to flush the toilet or water plants. During hot weather, HydroSKIN releases water to cool the environment by evaporation. The aim is to reduce the risks of flooding and heat in cities by relieving the burden on sewerage infrastructure and ensuring natural microclimate regulation.
The special fabric consists of three layers. The outer layer is a water-permeable fabric that protects the inside from dirt particles and insects. An intermediate fibre layer provides increased water absorption and evaporation. The film on the inside drains water to the lower profile.
HydroSKIN was introduced to the public on 4 October 2022 and this year received the German Design Award Gold 2024 as a product that inspires and serves as a model for the entire industry.
