Energy and emission analyses of renovation scenarios of a Moscow residential district

Three building level renovation concepts of a typical Moscow residential district are defined and their energy saving potentials evaluated in a recently published study [1]. This study extends these analyses and concentrates on energy and emission analyses of different energy renovation solutions and energy production alternatives at the district level using the same case district as in the previous study [1]. At the district level, four different energy renovation scenarios, called Current, Basic, Improved and Advanced, were analyzed in terms of energy demand and emissions. Considerable energy savings could be achieved, up to 34% of the electricity demand and up to 72% of the heating demand, using different district modernization scenarios. As for the emission analyses, switching from natural gas to biogas would result in decreasing greenhouse gas emissions, but increasing generation of SO2-equivalent and particulate emissions. A better solution would be to still switch to biogas while maximizing renewable energy production from local non-combustion technologies at the same time
