The construction industry’s constantly expanding operations have an impact on the environment and resource depletion. These impacts together with short lifetimes of buildings emphasize the importance of urban mining activities applied to buildings. Urban mining is a crucial measure to improve resource efficiency that aims to maximize recycling rates in building materials in order to lower the environmental impacts of building construction. The objective of this study is to adopt urban mining to a sustainable building. For this purpose, all components (foundation, exterior walls, interior walls, and roof) of a sustainable building are integrated into the UMI tool. The closed-loop and loop potential results of the building components are obtained from the UMI tool. In the post-use phase, the material type with the highest percentage in closed loop potential calculations for each component is energetically recyclable, fossil or disposable. In interior walls, higher downcyclable material potentials are observed. One reason for that might be that there are no external effects on the wooden materials, especially in interior non-bearing walls and doors. In roof design, downcyclable materials for the post-use phase is again higher, due to timber and coniferous wood and wood fiber insulation boards. As a result of loop potential calculations, downcyclable and energetically recyclable, renewable material types have the highest percentages. Urban Mining Indicator is calculated as 59.6% in the tool.
