Development of a sustainability framework for glass fiber reinforced concrete (GRFC) facade panels with life cycle assessment (LCA) method

The construction sector is responsible from 40% of global raw resource consumption and global warming. A "Life Cycle Assessment" (YDD) method has been developed to detect and reduce the environmental impacts of products and services. For this reason, it is important to identify and analyze the environmental impact of the sector. LCA is a method of analysis used to determine the environmental impacts of different stages of the process of removing, using, and disposing of a product's material. Within the scope of this thesis, glass fiber reinforced concrete (GFRC) facade panels with steel carcass and heat insulated panels; During the process called "cradle-to-cradle option" in the LCA method, the environmental sustainability performances of the panels are revealed by the CML(Center of Environmental Science of Leiden University) method. By using global warming effect tree diagrams, the materials and processes that have the most negative effects on the sustainability of the products have been identified. With the changes made to the required points, ecological product alternatives have been developed and modeled in YDD software. These products are named as eco-steel carcass and eco-heat insulated panels and compared with the first products in terms of environment in terms of YDD method. Sustainability performance has improved by 10-70% in the different impact categories compared to the first products in the products called ecological products. Based on the LCA of glass fiber reinforced concrete facade panels, sustainability conceptual framework established for building materials. This framework, which will be useful in creating a sustainable material database, also refers to the sustainable building.
