Title: Valdes rätt betongstomme? Miljö och ekonomi för byggnadsstomme i betong

Abstract: Economy is and has always been the basis for any investments to get the most value for your money. Today, when environmental debate gets a lots of room in media, the environmental impact has to be considered in the decision of which alternative to choose. The report describes the result of a capital budgeting and a simplified Life Cycle Assessment (LCA) with a focus on carbon dioxide, nitrogen oxides and sulphur dioxide and for the concrete structure of CHABO, a block of student flats at Chalmers university campus. We have compared two different ways to build, on site with in-situ concrete and a facade of bricks and one alternative with precast concrete elements which would serve as a facade. In order to link the economy to the environmental impact the concept of eco-efficiency is used. The results show that the prefabricated option is clearly better with respect to carbon dioxide and sulphur dioxide emissions, while emissions of nitrogen oxides and dust are broadly similar. Emissions of carbon dioxide can be largely attributed to the cement and gypsum production while the shipping by boat is responsible for the emissions of acidifying substances.
