Tiivistelmä
The construction industry is one of the major contributors to global CO2 emissions that pose challenges to our environment. For the construction industry to reduce its carbon footprint, an understanding of its contribution from material consumption to methods of construction is essential. This master's thesis aimed to assess the amount of greenhouse gas emissions, eutrophication potentials (EP), and acidification potentials (AP) associated with building a 3-bedroom bungalow in Nigeria. In addition, the land use effect of building a 3-bedroom bungalow was assessed. Using life cycle assessment and land use methodologies, the case building in Nigeria was assessed. One click LCA was used for this analysis and the focus of the analysis was cradle-to-practical completion of the construction.
The obtained result from the analysis showed that the GWP for the scope of the study was 54.8 t CO2eq, while AP was 223 kg SO2eq and EP was 33.7 kg PO4eq. The majority of the carbon emissions were from material production which accounts for 91.6 percent of the obtained GWP. The vertical structures and façade contributed the most impact (55 percent) in terms of structure. The obtained result suggests that improvements can be made to reduce carbon emissions through sustainable material choices.
Additionally, an assessment of the land use (occupation) efficiency indicator suggests that it is more beneficial to transition to a multi-family apartment building, as it addresses the issues of loss of wildlife and availability of land for agricultural purposes.
The findings from this study highlight the need for sustainable practices and solutions in the construction industry in Nigeria, as a measure against the environmental impacts. By considering the result of this study, the government and stakeholders concerned can make better decisions that focus on emission reduction within the industry. Furthermore, this can lead to improved resource efficiency and better encourage responsible land use.
