Sammanfattning: Historically, most of the climate impact of a building has derived from the buildings operational phase. However, recent studies show that the climate impact of the construction phase of a building is of the same dimension as the operational phase. Current building regulations regard the energy performance of buildings, excluding any obligations of reporting the environmental impact of the building during its life cycle. In 2017, Boverket was commissioned by the Swedish government to develop a proposal for a new climate declaration of buildings based on a life cycle perspective. The application of life cycle analysis in the Swedish building and construction sector is limited, and in particular when considering single-family buildings. Thus, the aim of the thesis is to investigate the applicability of the life cycle analysis methodology to single-family buildings and compare with former studies on multi-family buildings. This is done by studying the climate impact of a single-family building through a life cycle perspective. Simulations are done in the simulation tools VIP Energy and Byggsektorns miljöberäkningsverktyg BM. The result of the study show that the climate impact of the building is equally distributed during the building’s constructional and operational phase, accounting for 50.1 % and 49.9 % relatively. The total climate impact through the life cycle of the building is 541 kg CO2-eq/m2 Atemp, which is somewhat consistent with results of previous studies on multi-family buildings. The result also shows that the material production and the energy use are the processes that contributes the most to the climate impact during the life cycle of the building. Furthermore, the result indicates that there are no significant differences in the methodology of life cycle analysis between single-family and multi-family buildings.
