ABSTRACT
Because of short construction periods the material moisture is a well known problem in new buildings. In many cases a high humidity in the indoor air causes mould growth and an increase of the heating costs. This paper briefly describes the influence of different methods of construction to the indoor humidity and more important on the surface moisture conditions. The difference between mineral constructions with reinforced concrete, different timber constructions and mixed constructions, in which concrete construction parts fulfill static requirements and prefabricated wooden construction elements form the building shell will be discussed.
