… help of AK Consultancy Indoor Air AB, formed a series of questions regarding moisture problems in buildings and how these are handled in extreme climates with high temperatures and a high relative humidity. Furthermore to analyse and indentify key material that makes a …
… unit is greatly increased and the pellets are more homogeneous with regard to moisture content, particle size and density compared to unrefined fuels like forest residues and chips. For further development of the Swedish pellet industry, the use of different assortments from …
En fallstudie av ett projekt där ByggaF-metoden har använts
The so called ”ByggaF-method” is a relatively new Swedish method to stop moisture from being built into a building. The method should prevent damages on buildings as a result of mould growth and moisture. The purpose of the method is to include moisture control in the entire …
… tree compartments of spruce (Picea abies (L.) Karst) were related to the moisture conditions of the site. Five plots at Risfallet (60º 21´ N, 16º 13´ E), was placed along a moisture gradient in a 40- year spruce stand. Stemwood, bark, branches and needles were analysed for 25 …
