Abstract
Log construction has a long and rich tradition in Northern Europe, yet the rising demand for energy-efficient log housing poses challenges for designers seeking optimal hygrothermal performance. One proposed solution involves utilizing a double-log structure, integrating thermal insulators between two log layers to maintain heritage while enhancing thermal resistance. This study addresses the complexities of designing energy-efficient log buildings in cold and arctic conditions and investigates steady-state and dynamic approaches to hygrothermal assessments. Emphasizing various cold climate scenarios, hygrothermal design intricacies, moisture safety considerations, and critical parameters impacting building performance, the research fills knowledge gaps in design strategies and highlights the risks associated with the double-log structure.
