Wireless Sensor System for Intelligent Facades

Syracuse, NY

The integration of a wireless-transponder system into building components (“intelligent building materials”) with built-in relative humidity and temperature sensors (RH, T) allows for a cost-efficient and non-destructive measurement of data regarding the current hygrothermal conditions of a building. Even during long-term use, quality assurance of the building system can be achieved by “looking into” the component. This supports the sustainability of the building from both a technical and an ecological point of view. In this paper, the development, the functionality and the exemplary application of Radio Frequency (RF), as well as an hygro-thermal analysis for solving the challenges of building-climatology planning is presented. Built on the measurement data of a real case study, the results of hygrothermal simulation tools are confirmed. Based on this, the use of thermal insulation in buildings for energy saving has been verified and the implementation into a hygrothermal simulation tool is shown. For the verification of results, a case study in Berlin was chosen, in which interior and exterior temperature and relative humidity values were recorded. Even with the peculiarity of irregular user behaviour of the building, good accordance between measured and calculated values could be achieved. Based on the analysis and evaluation of measurement data, as well as the implementation of hygrothermal simulations, the presented study provides a guideline for planning of ETICS with particular respect to extremely climate conditions.
