Abstract: One key issue in wood construction is durability which is determined by construction details and the resistance of the material against biological deterioration and wetting. The service life of wooden commodities is dominated by occurring moisture loads on the one hand and their capability to withstand moisture on the other hand. Hence, climatic factors have a direct impact on the material climate and thus on service life. However there is still a lack of knowledge about the relationship between material climate and local weather conditions. Therefore the aim of this study was to quantify this interaction.

Within this study wood moisture content and wood temperature were recorded for combined façade-decking elements made from Douglas fir heartwood and Scots pine sapwood exposed at eight different locations in Europe, namely Bergen (Norway), Ås (Norway), Borås (Sweden), Ljubljana (Slovenia), San Sebastian (Spain), Ourense (Spain), Portsmouth (Great Britain) and Hannover (Germany). The moisture performance of the wooden materials was set into context with local weather parameters.

Orientation of the facades had a major impact on the moisture performance. Moreover the horizontal exposition experienced higher moisture loads compared to the vertical. Differences between test sites were determined and could be explained with different climatic loads impacting on the construction.
