Theoretical-experimental analysis of selected passive timber house wall

Abstract

The advancing times and legislation require constant research of new progressive building envelope structures. Walls based on wooden material are perspective in this regard. These are capable of elimination the wall thickness while providing the required thermal resistance. The pavilion research of KPSU UNIZA laboratory includes this kind of wall structures intended for passive wooden houses. This paper deals with one of the researched wall assemblies in the annual operation. The measurements show that such a construction is suitable for near to zero energy buildings. It also points out that the correct design can eliminate thermal bridges in the area of the load-bearing wooden studs.

External Wall Systems in Passive House Standard: Material, Thermal and Environmental LCA Analysis

“…Computational and in situ studies confirm a number of positive properties of such a solution [59][60][61]. The most frequently discussed property is thermal resistance, which allows for reducing the thickness of the external wall partition while maintaining high resistance to heat [62][63][64]. At the same time, the frame construction of external walls enables the elimination of thermal bridges, thanks to the use of additional insulating partitions.…”
