Flervåningshus med trästomme : Uppfattningar från projektering, byggproduktion, boende och förvaltning

Sammanfattning: The purpose of this study was to illustrate the perception on multi-storey construction with structural timber of four categories of respondents connected to three specific case studies in Sweden. A qualitative approach was implemented with interviews of the respondents in order to investigate perceptions of mainly problems and attitudes. Results from the study showed a positive attitude towards wood as a general building material as well as a structural frame-work material for multi-storey buildings from all categories of respondents. Problems were mostly mentioned from respondents in phases of planning and production. The most commonly mentioned problems were the lack in experience and knowledge, the costs, the weather protection and the strictness regarding moisture. The end-users stated commonly that they did not experience any issues. Although the most commonly mentioned perception of problems was the flutter in the structure from wind. From the perception of estate managing, the frame-work material did not matter too much. The estate managing had to adapt to given condition no matter what type of material. Wood in the framework did not present more problems than any other material. Additional findings showed that a majority of respondents in all groups of stakeholders shared the perception that the method will have a positive growth and development for the future. When considering sustainability aspects it was a common perception that wood frames offer benefits in environmental sustainability and social sustainability for both work and living environment. Research limitations from this study constituted of the small selection and limited range of case studies and, derived from this, the small amount of interview respondents. Practical implications from the study showed that focus on problem solving should be about increasing experience and knowledge in the building sector and increasing cost effectiveness. The study presented perceptions from informed respondents from different categories involved in three different case studies. The results of this study can be used to present, confirm and invalidate current perceptions of problems with multi-storey buildings with structural timber. This in order to establish future measures for development.
