Abstract
The purpose of this report is to examine whether there is any connection between the multi-storey wooden buildings, industrial construction and environmental impact. In the early 1960’s prefabricated parts were used to build “Miljonprogrammet”. This led to the streamlining of the construction process but the houses were often ill-suited for those who would live in them. Traditional building became the standard way of building again in the 1970's when the demand for housing fell again. Today there is again a positive outlook for industrial construction, largely because of the construction sector need to be streamlined and enhanced. But better profitability and improved quality is also requested. In manufacturing, there are different... (More)
The purpose of this report is to examine whether there is any connection between the multi-storey wooden buildings, industrial construction and environmental impact.

This led to the streamlining of the construction process but the houses were often ill-suited for those who would live in them. Traditional building became the standard way of building again in the 1970's when the demand for housing fell again. Today there is again a positive outlook for industrial construction, largely because of the construction sector need to be streamlined and enhanced. But better profitability and improved quality is also requested. In manufacturing, there are different production principles. The companies involved in industrial construction are inspired by these approaches and have adapted them according to their conditions. In order to build in wood, certain material properties have to be taken into account, such as fire, acoustics, moisture and stability. It has until 1994 been forbidden to build more than two floors in wood in Sweden. Therefore the market for apartment buildings has been dominated by concrete buildings. However, the wood is well placed to compete, especially because of the expertise in industrial production in the wood processing companies and the fact that the companies producing single family houses have been using industrialised processes for a long time. In order to assess a product's total environmental impact a LCA can be done. There are different results depending on method selection, but the wood often shows good results. Wood is a renewable resource that is part of the natural carbon cycle, where the felled trees, are replaced with new plants and thus there are always new trees that can take up the carbon dioxide emitted during combustion of wood products. The study is a case study conducted on a block of flats being built in the Västra hamnen in Malmö. A new building system has been developed and the project we have looked at is the first that is built with the system. The new system is based on lumber and is suitable for 4 to 8 floors. It is developed by Tyréns and Derome. The basic idea was to develop a system that would seek processes separated from the specific projects. They wanted to have standardized solutions, but varying buildings. Carbon emissions and energy use are environmental aspects taken care of while building. Sustainability and the question whether materials are renewable or not is also relevant to the issue. Wood exhibits excellent properties in terms of environmental issues and there is a potential to use the material environment effectively. It is a renewable material that is part of the natural carbon cycle. It is however not obvious that all solutions should be made of wood. Perhaps there is a potential to mix materials and use the material which is most effective. Industrialised construction should lead to transfer of knowledge and continuous development on the environment. This requires that environmental considerations are a priority and may be seen as something that provides increased customer value. By using the required weather-protection there will be pros and cons. Weather protection entails a relatively high cost and the platform can be used only on one floor at a time while making exterior work. The benefit is a dry work environment that is positive for the building and construction workers. (Less)
