More information


At a test building on the test field whole wall segments can be torn down and reconstructed. The building is air-conditioned in winter to an indoor climate of +20 °C and 50 % r.h. Test duration is at least a period of 6 month up to several years. Temperature and moisture measurements on the wall sequence can be used for validation of WUFI® simulations.
