In the paper, the retrofitting process in a district was examined to understand its effects on energy consumption and environment via Life Cycle Assessment (LCA) methodology. Correspondingly, waste recovery potential was evaluated to obtain energy recovery rate from retrofitting processes. The methodology was set based on LCA, which covers cradle-to-grave approach to evaluate the steps of retrofitting activities on a district that have 82 building blocks with a total 41168 m(2)conditioned area. The aim of the retrofitting is to improve energy performance of the buildings and increase percentage of renewable energy sources on total consumption. While the applied interventions decrease the energy consumption, they further have negative effects on environment because of their production, transportation and end of life stages. Therefore, boundaries of the study were defined to analyze the applied interventions effects from raw material extraction till disposal. Hence, waste management processes of the retrofitting materials were proposed and evaluated.
