Abstract

The German and European climate action programs and the ongoing discussion of resource efficiency require an in-depth analysis of the building sector, especially with the background of the German refurbishment backlog and high energy demands of the German building stock. A Life Cycle Assessment (LCA) on the city quarter level allows fast and efficient evaluation of environmental impacts, emissions, and energy demands of densification in urban areas. This study presents LCA results for a specific urban city quarter. Thereby environmental and energetic values for specific building ages are developed and used to conduct LCA for the building construction and technical building services components. A 3D city model in CityGML-format of residential buildings serves as the basis for assessment. The results can be used to identify decisive drivers of energy demands and emissions and the saving potentials of different building development scenarios.
