The building construction business in Sweden stands for approximately a third of greenhouse gas emissions nationally. Great focus on environmental work and a good attitude towards a climate-smart construction process have today evolved to a genuine discussion about the way that fits in to secure future generations. Wood construction, an old but continuous method are today under a growth process to cater for the need of housing. Wood construction on a high level however has its difficulties environmentally and economically, where high wood construction buildings have possibly been seen as unnecessary especially in higher apartment buildings. But with time and development forward has it been found that concrete has a high carbon dioxide emission value when producing apartment buildings and the thought of using wood instead has been increasing in the business. The municipality of Eskilstuna is planning a new residential area in Norra Årby, where three apartment buildings is planning on being built on a deserted parking lot. The designers of these three apartment buildings are examining the possibility to use wood as a main construction material instead of concrete. As a mission of Kommunfastigheter i Eskilstuna AB explores this study this possibility using LCA and LCC over a period of 50 years on one of these buildings that can be later used for future projects. Out of documents on the designers thought of construction has LCA och LCC been produced in the shape of global warming potential per square meter living space and price per square meter living space. The results of LCA and LCC showed that it is cheaper building the apartment building in wood in comparison to concrete, and that the global warming potential was significantly smaller even though the building is designed to be 9 levels. Wood can therefore be used as a substitute for concrete even though the building is high. To secure the results a sensitivity analysis was produced to see of changing the parameters of the study had an impact on the results. This showed that the most significantly economical parameter was the discount rate of the projects.
