Skog eller gruva : En kostnads- och miljöjämförelse mellan limträ och stål som bärande stomme i en hallbyggnad

Sammanfattning: This thesis provides a cost and environmental comparison between an industrial building with glulam or steel as structural frame. Based on the project Kungsleden Industrihotell, by the company Kungsleden AB we make a comparison of two alternative bearing structures. The total length of the building is 96 meters and has a width of 25 meters. The dimensions of both a structural system frame of glulam and steel were calculated according to Eurocode standards. Based on this, the bill of materials has been calculated. Furthermore, for the quantities and dimensions of the two buildings, a cost calculation for materials, labour, fire protection and demolition have been performed. An environmental analysis with determination of carbon dioxide equivalent emission from production, transportation and recycling was carried out. The results of this thesis shows a price difference between the structural frame of the respective materials of about 200 000 SEK in the glulam's advantage. The simplified environmental analysis demonstrates that the glulam frame releases 1/3 of the equivalent carbon dioxide emissions in relation to the steel frame.
