Abstract: This paper focuses on evaluating the technical, economic and ecological effects of the transition from the current high temperature charts to the lower temperature charts in the Moscow DHS by means of a developed spreadsheet-based model. A methodology suitable for assessing results of potential transition to lower temperatures in DHS of cities in Russia and worldwide is proposed and implemented in the model. The reference case of 2016 and three cases with decreased heat demand in buildings by 5, 10, and 20% were considered. The results show that fuel savings of 678–872 ktce a can be achieved with respect to the current temperature charts in the Moscow DHS. The 110/50°С temperature chart is the most profitable option, with net present values varying from 4.64 to 10.74 bn RUB depending on the case. The 95/50°С chart, which leads to a reduction of 1.325–1.387 MtCO2/a, has the least impact on the environment. A more significant CO2 emissions reduction can be achieved by strong energy-saving measures and broad utilization of renewable and waste energy. The essential prerequisite for the transition is a reduction of the heat demand in buildings by at least 20%.
