Piezoelectric Textile Facade for the energy supply of active sensor technology with regard to data management for circular economy in building construction

The high GWP potential of construction requires a holistic approach such as circular economy. Currently, common joining, construction and planning practices result in heterogeneous assemblies of different components that are difficult to deconstruct. Furthermore, there is currently little information and data on building components used and the climatic impacts on them. In this context and with the intention of recording long-term (circular) processes in construction, the Piezo-Klett basic research project (FFG no. 879459) funded by the Austrian Research Promotion Agency (FFG) deals with the energy supply of active sensor technology in construction by combining the hook and loop fastener with piezoelectric components. The aim is to open new perspectives on sustainable energy production systems by transforming buildings into energy carriers and generators, analogous to a “battery”. To this purpose, the result presented in this conference paper is a description of the constructive structure (climatic impacts, construction, piezo technology) of a “Piezoelectric Textile Facade” as well as test results on piezo tapes. This opens new possibilities in the context of the application of hook-and-loop fasteners, the energy supply of active sensor technologies as well as in the field of data acquisition and data management.
