| Description: | For new buildings and for existing buildings, it is essential to ensure compliance with the minimum thermal insulation and the increasing energy requirements of the building envelope (Energy Saving Ordinance). The requirements for the protection of historical monuments make the use of interior insulation on exterior walls necessary, especially in the case of renovations and existing buildings. The aim of the project was to counteract moisture formation/accumulation by means of a sensor-controlled on/off function of a thermovariable inner layer between masonry and interior insulation. For this purpose, a contactable chip module was developed for the measuring system to detect the condensate in the material. The module is characterized by a high insensitivity to disturbance variables such as high humidity, recurring continuous exposure to condensate and heating (evaporation) as well as chemical segregation of the surrounding building materials at the measurement location. The energy supply is automatically activated if necessary. If there is no (more) moisture accumulation in this area, or the moisture has escaped by drying, the energy supply is automatically switched off. This sensor-controlled regulation (activation/deactivation) also ensures energy-saving operation. The applicability of the chip module in and with the measuring system was proven by means of laboratory tests in different wall construction samples and field tests by the project partners. |
