dc.description.abstractIn accordance with the Paris Agreement and Sweden’s national climate action plan, the construction industry is to achieve climate neutrality by year 2045. To succeed, all disciplines within the sector need to take responsibility and make considerable actions to reduce their climate impact. Through identifying climate impact reducing measures within the structural, electrical and HVAC engineering disciplines that are suitable for residential building projects, this thesis aims to contribute to the advancement towards a climate neutral construction industry. The study consists of a literature review, an interview study and a life cycle assessment (LCA). The literature review resulted in suggestions of several measures of reducing climate impact. The measures were discussed and evaluated both through an interview study and an LCA. The interview study encompassed interviews with two environmental coordinators and one representative from each of the studied disciplines. Findings indicated a willingness and need to learn more about climate impact reducing measure and the LCA-methodology. The LCA was conducted according to the SS-EN 15978:2011 standard, encompassed a time period of 60 years and the system boundary A1-A3, A4, B4-B7, and C1-C4. Through a multiple scenario analysis, the suggested measures were evaluated both individually and collectively. The combined scenario, where green concrete, cellulose insulation, photovoltaic cells, and smart ventilation were incorporated, achieved a reduction of 7.91% in global warming potential (GWP) which corresponds to 80 000 kg CO2-eq or nine Swedes’ annual climate impact. Results indicate that LCA can induce pro-environmental decision making through comparing different scenarios and identification of environmental impact reduction opportunities throughout a building’s life cycle. It was also identified that although widespread implementation of current technologies can contribute to substantial reductions in climate impact, extensive actions of climate compensation are still required to achieve climate neutrality. Thus, mainstreaming of best practices needs to occur in parallel with development of disruptive technologies and innovations to achieve climate neutrality.sv
