Abstract: The district heating system (DHS) is an efficient way for heat supply in urban areas. The efficiency of the DHS is considerably increased with the modern developments of technology, introducing 4th and 5th generations of centralised DHS. The existing DHS in Ukraine needs energy-efficient modernisation, where the reduction of heat losses at buildings and pipelines, the low temperatures of heat carriers, the use of heat pumps and individual heat substations with measuring devices and automated control are needed. The work proposes a novel methodology of transition to 4th generation DHS that allows its implementation with limited funds for investment. It consists of the step-by-step realisation of required innovations that allow optimising investments schedule and payback time. The methodology is illustrated by two case studies. In one of them, the university administrative building built 50 years ago is considered. The proposed improvement method can decrease the total energy consumption by 85%, with investments lower by 47% compared to traditional simultaneous realisation. The introduction of a new generation of DHS in Ukraine can be performed by gradual additions of new elements to existing DHS and integrating individual heat substations with heat pumps and renewable energy sources.
