Whole Life Carbon Assessment of Renovation

This technical report discusses the Whole Life Carbon Assessment of Renovation, focusing on the possibility of specifying limit values for Life Cycle Assessment (LCA) in renovation work. The report outlines the importance of optimizing energy efficiency and material choice during renovations to reduce environmental impact. It aims to analyze the feasibility of establishing requirements for the environmental impact of renovation projects, promoting renovation over demolition. The methodology includes categorizing renovation types and defining limit values based on collected case studies. The report presents findings from twenty-nine major renovation cases, highlighting variations in environmental impact and the necessity for robust energy data. Recommendations are made for future LCA requirements, emphasizing the need for alignment with existing building regulations and the establishment of specific criteria for different renovation types. The report underscores the construction sector's significant contribution to greenhouse gas emissions and the urgent need for sustainable practices in building renovations.
