| Abstract [eng] |
The construction sector accounts for a significant portion of CO2 emissions, around 40%, which contributes to global warming. In order to reduce the environmental impact of construction in Lithuania, a law will come into effect on January 1, 2024, stating that at least 50% of organic and wood-based construction materials must be used in the construction of public buildings. This aims to promote the active use of secondary raw materials and reduce construction waste. This master's thesis analyzes how the universal warming potential generated during construction changes when different prevailing materials are used for the construction of the same high-rise residential building. The study uses data from a multi-story residential building located at Brasta str. 22 C, Kaunas. Based on the literature analysis, it was determined that the construction of high-rise buildings using timber can contribute not only to mitigating global warming, creating additional jobs, but also to reducing real estate prices by choosing modular construction and minimizing construction time and waste generation. A survey was conducted to assess people's attitudes towards timber as the prevailing construction material and its contribution to the environment. An analytical numerical evaluation was also performed using the software "One Click LCA" to calculate the universal warming potential quantities generated during the production, transportation, and collection/construction of construction materials when the prevailing material is used for exterior walls, floors, and roofs. All calculations were performed using the following prevailing materials: brick (for exterior walls), reinforced concrete, timber. The analytical evaluation was conducted by comparing the results among different materials. |
