Cost-Effective District-Level Renovation: A Russian Case Study

This chapter analyzes the costs of adapting three different holistic energy renovation concepts both in the buildings and in the corresponding residential district in Moscow. In the buildings, the estimated costs included both mandatory less-energy-efficient repairs and suggested energy-efficiency improvements, focusing on reducing heating and electricity demands, reducing water use, and improving ventilation. At the building level, the costs of different renovation packages varied between 125/m² and 200/m² depending on the renovation package. The estimated district renovation costs include both the renovation costs of the buildings and the costs of improving district energy and water infrastructure. At the district level, the costs of the main cases per inhabitant varied between 3360 and 5200. The net present values for different building and district-level renovation packages for a 20-year period suggest that renovation of a district may be more feasible than renovation of individual buildings.
