Lufttäthet i klimatskalet hos temporära byggnader uppförda med husmoduler

- Abstract
- The industrialization of the Swedish construction industry has long stood in the shadow of the traditional construction methods. Problems such as high costs, long construction times and tough regulations have made the development stagnate. However, the industrial manufacturing industry has shown rapid growth within recent years. The culture within the industry has changed through innovative construction systems like houses built with interconnected modules which are created in a factory. The modules can be seen as potential solutions to the shortage of houses in Sweden and the increasing regulation requirements.

- The industrialization of the Swedish construction industry has long stood in the shadow of the traditional construction methods. Problems such as high costs, long construction times and tough regulations have made the development stagnate. However, the industrial manufacturing industry has shown rapid growth within recent years. The culture within the industry has changed through innovative construction systems like houses built with interconnected modules which are created in a factory. The modules can be seen as potential solutions to the shortage of houses in Sweden and the increasing regulation requirements. The overall purpose in this study is to provide an understanding of how to build with housing modules and how to achieve an airtight building envelope in impermanent houses. When establishing short-term buildings with housing modules, such as temporary schools and offices, there are difficulties achieving an airtight building envelope, since the building must easily be dismantled. Due to new rules regarding air leakage in newly built houses in 2015, old module housing must be improved as they are considered a new building every time they are established on a new site. A literature study has been performed to gain a deeper understanding of how the production system with the housing modules works. The literature study goes on to describe the benefits of an airtight house and the legal requirements. The method used in the case study is experiments consisting of compression test and infrared images. The experiments were performed to test air leakage in temporary houses, built with modules. These tests have been done in collaboration with Temporent AB which is one of the biggest companies, working with temporary buildings, on the Swedish market. The experiments were performed on the office module called KUBIK that faces problems with air leakage at the connections between the modules. The current method used by Temporent is to seal with insulating tapes between the modules. The technique, however, fail to attain a satisfying airtightness. The results of the case study shows that the building through the improvement decreases the air leakage slightly, yet the installation time and cost increases due to the seal and the new weather-strip. Openings in the buildings envelope also need to be improved by making it more airtight around windows and doors, which was made clear by the experiment. Efforts in the production process should be implemented to improve the quality of the modules. An example for this could be to instate regular checks on the work in the factory. The assembly of the seal has also a great significance for the buildings air tightness for they need to be placed and attached correctly. However, it is difficult achieving an airtight building with temporary modules. The industry will be forced to improve buildings due to the new regulation requirements, both through improvements in the production process and a better assembly of the seal. This will likely increase companies expenses and perhaps reduce their competitiveness on the market. (Less)
