Annotation: Renovation of existing buildings is now vital for maintaining the built environment‘s functionality and reducing resource waste. Although various assessment techniques and tools have been established, there have been several differences in the literature regarding the influence of these methods on the renovation process. Various research recommends integrating different already-in-use tools to improve access to a building‘s performance. The primary objective of this dissertation is to develop a methodology for environmental impact assessment for the renovation of residential buildings using a lifecycle approach. The dissertation presented the investigation of two existing methods (LCA and EPAS) and their indicators as a comparison study, to formulate the gaps related to the renovation process. The selected methods – the life cycle assessment and the environmental performance schemes – have been applied to a renovated multi-apartment building to comprehend the actual impacts and their credit distribution between the two methods. Additionally, a conceptual methodology that combines the lifecycle approach with environmental performance guidelines can be used to achieve a holistic approach to sustainability and circularity during the building renovation process. The developed methodology was applied to a case study to assess the environmental impact of renovated houses. The findings emphasize that 10% of indicators are significant to lifecycle parameters used from pre-design and in the development stage to evaluate the complete life cycle.
