Tiivistelmä
For more than 200 years, industrial civilisation has dominated over cities and caused devastating environmental impacts, including climate change, environmental pollutions, CO2 and greenhouse gas emissions (GHG), global warming, and many more. The construction industry accounts for almost half of CO2 and GHG emissions worldwide. Life cycle assessment (LCA) as a solution is an evaluation technique assessing a building's environmental impact and carbon emission from raw material extraction to disposal phase. A building’s potential environmental implications, energy demand, and carbon emissions are tracked and monitored by LCA from the early design phase to the end of the building’s service life. Accordingly, this thesis is aimed to minimize adverse impacts of residential buildings on the environment by introducing the concept of a low energy/carbon building, figure outing the factors affecting the quality of the building’s life cycle, and analyzing the LCA of the building via integrating the BIM tools. Therefore, seminal literature discussed LCA, energy and carbon relevant parameters in a residential building to reach this goal.
Furthermore, a chapter was devoted to BIM to emphasise the importance of the latest technology in easement and accuracy of data transfer for evaluating the LCA of a building. As the thesis case study, a sample residential model in Revit software located in Finland, Helsinki, is selected. The case study is treated from two different scenarios for LCA; the first scenario assumes the model as a low energy/carbon building (stud-frame), and the second scenario considers the case study as a Conventional building (concrete frame). The research methodology consists of qualitative and quantitative approaches. Data collection is carried out via seminal literature review, BIM tools, Revit and One Click LCA software. Data evaluation of LCA for two scenarios is done by One Click LCA platform, and comparison was carried out to differentiate the result of LCA between the two scenarios. Consequently, the summary of findings is presented as outcomes of the investigation. Last but not least, the conclusion summarizes the thesis and its scientific results, and for improvement of the research for further studies, some recommendations are proposed.
