Koldioxidutsläpp och energianvändning vid husbyggnad med betongstomme : En studie av två flerbostadshus inom projektet Sågklingan/Pilen i Västerås

Purpose:  The purpose is to investigate the use of concrete as a frame material and its effects on carbon dioxide emissions and energy use. Carbon dioxide emissions and energy use are examined from the production stage to the management stage 100 years in the future. In addition, investigate other material compositions in concrete to study the possibilities 0f lower carbon dioxide impact and energy use. Method: The methods used have included investigating one construction project involving two multi-family houses with the same conditions. The investigation conducted is primarily made through calculations of CO2 emission and energy use. Furthermore, a literary study has also been conducted focused on investigating what the impact concrete has on the environment and what different alternatives are available to reduce potential carbon dioxide emissions and energy use in house construction with a concrete frame. The study has focused on both the production phase and the management phase. The construction stage has been investigated primarily within the concrete production, enforcement and including transports. Whereas the management stage has been studied upon the energy use of the buildings and its effect on carbon dioxide emission.  The literature study deals with methods that can be associated with the case study but will also deal with other presumptive methods. Results: The study of the construction project shows that CO2 emission and energy use primarily comes from cement production within the production stage. Whereas, looking at the whole life cycle studied, the primary contributor to CO2 emissions and energy use over time is the management stage of the buildings. The result also shows that by using renewable steel as reinforcement can significantly effect the energy use, as well as, CO2 emission of the production phase. Conclusions: The cement production is one of the biggest causes of CO2 emissions and energy use in the production phase of the studied life cycle. While the management phase is the largest in terms of the total life cycle studied. Several methods are possible to decrease the use of energy use and CO2-emission in the production stage, and to combine those methods is an alternative that suggested
