Wood as a natural material is highly useful across many different industries. It can be processed into various wood composites, glued wooden elements, veneer, solid wood, and much more. Its service life, however, greatly depends on the wood species, conditions of use, and how well the wood has been protected for those specific conditions. One of wood’s main characteristics is its moisture fluctuation, which can be both beneficial and problematic. In this thesis, we monitored the moisture content of wood in a prefabricated wooden structure to determine how wood moisture fluctuates under different weather conditions, as well as how moisture levels vary at different measuring points within the structure. We measured moisture content by installing sensors into the construction of an existing model prefabricated building. These sensors measure wood moisture content, temperature, and relative air humidity. The measuring points were placed at the most critical details of the wooden structure, allowing us to gather the most data for variable analysis. The results showed that the wood never exceeded the moisture level at which fungi and mould could begin to develop. The highest recorded moisture content was 17.6%, while the lowest was 13%. In a second case, we monitored wood moisture in a single-family house that features a 300 mm high concrete base detail under some of the exterior walls. We compared the moisture content in walls that rest directly on the foundation slab with those placed on the concrete base. We found that the moisture levels between the two measuring points did not differ significantly.
