Growing interest in reducing the carbon footprint of new buildings has led to the increased use of cross-laminated timber (CLT) in construction. Despite its environmental benefits, the hygrothermal performance of CLT structures remains a critical issue, particularly during the construction phase, when the wood’s sensitivity to moisture becomes paramount.

Despite its environmental benefits, the hygrothermal performance of CLT structures remains a critical issue, particularly during the construction phase, when the wood’s sensitivity to moisture becomes paramount. While existing research has addressed the mechanical properties of CLT constructions, there is a noticeable gap in the investigation of their long-term building physics performance. This study presents an in-depth analysis of the hygrothermal behavior of a CLT residential building in central Germany, with a particular focus on the exterior walls. To capture real-time data, extensive wireless RFID sensors were strategically placed within the component structures to monitor temperature and relative humidity. The analysis focuses on two consecutive winter periods during which the building is (1) under construction and (2) occupied and examines the moisture behavior of the CLT construction during these periods. The results emphasize that moisture levels within the CLT wall assembly are significantly affected by construction-related moisture content and the building’s operational environment.» weiterlesen» einklappen
