ABSTRACT

Sufficient dry-out capacity of the constructional moisture is important for solid wood structure wall assemblies, especially with a non-ventilated façade system. The objective of this study was to create a validated simulation model of a Massiv-Holz-Mauer (MHM) panel external wall with ETICS (External Thermal Insulation Composite Systems) based on the field measurements. Field measurements were carried out in a two-floor wooden detached house. Temperature (t) and relative humidity (RH) were measured between the material layers of the external wall. Results of field measurements were used to create and validate a one-dimensional simulation model. It was concluded that the validation of the created simulation model was successful, and simulations were very similar to the field measurements. The simulation model can be used for future studies to evaluate the hygrothermal performance of the MHM panel envelope with ETICS.

摘要

足够的建筑水分干燥能力对于实木结构墙组件非常重要，特别是对于不通风的立面系统而言。这项研究的目的是基于现场测量结果，使用ETICS（外部隔热复合材料系统）创建Massiv-Holz-Mauer（MHM）面板外墙的经过验证的仿真模型。现场测量是在两层楼的木制独立式房屋中进行的。温度t测量外壁材料层之间的相对湿度（RH）。现场测量结果用于创建和验证一维仿真模型。结论是创建的仿真模型的验证是成功的，并且仿真与现场测量非常相似。该仿真模型可用于将来的研究，以评估带有ETICS的MHM面板封套的湿热性能。
