Abstract
The purpose of this thesis is to make a sensitivity analysis of buildings in Växjö municipality relative future climate change, where the climate is expected to become warmer and more humid. Building constructions are analyzed in terms of moisture performance and how climate change may affect the moisture related durability of buildings. This thesis is limited to buildings with wooden frames operating as temporary housing as hostels and Bed & breakfast, which Växjö municipality has supervison over. The focus is to study if parts of the buildings risk problems with mould or moisture in the current situation and how the buildings can be affected by a warmer and more humid climate. The issue is also to study how moisture problems can be... (More)
The purpose of this thesis is to make a sensitivity analysis of buildings in Växjö municipality relative future climate change, where the climate is expected to become warmer and more humid. Building constructions are analyzed in terms of moisture performance and how climate change may affect the moisture related durability of buildings. This thesis is limited to buildings with wooden frames operating as temporary housing as hostels and Bed & breakfast, which Växjö municipality has supervison over. The focus is to study if parts of the buildings risk problems with mould or moisture in the current situation and how the buildings can be affected by a warmer and more humid climate. The issue is also to study how moisture problems can be prevented and avoided. The survey is a visual assessment of the building units such as the buildings foundation, walls, facade and roof. Measurements of moisture content in beamed attic space and the buildings foundation were randomly chosen. Relative humidity and temperature were measured in ambient air. In this survey 5 out of 8 investigated buildings showed moisture and mould problems in the foundation with high readings of relative moisture in constructions, odour or availability of organic matter. For three of the buildings there was odour related problems attached to the indoor air. In two buildings visible mould in attic respective basement, could affect the indoor air. This may indicate moisture and mould damage in the studied buildings, but these buildings need to be investigated further to determine if there is any damage and which remediation action should be taken for each building. Climate change will place greater demands on existing buildings in Sweden. Buildings will be strained by increasing precipitation and more frequent weather phenomena. This research shows that 5 out of 8 investigated buildings do not have any action that prevents ground moisture to reach the buildings foundation. (Less)
