The present work is aimed at analyzing the heating system operation in academic building No. 7 and developing measures to modernize this system with an evaluation of economic efficiency. The analysis involved a thermal analysis of exterior wall envelopes, an on-site inspection of the heating system, as well as measurements of internal microclimate parameters and thermal imaging. Heat losses in rooms were calculated, and a verification hydraulic analysis of the heating system was performed. The inspection revealed deficiencies in the operation of the existing heating system, and two options for modernization measures were developed to address these deficiencies. The first option consists in adjusting the system (removing and adding sections; replacing window seals; replacing piping with that of a different diameter; installing manual balancing valves on risers and branches; installing a pump on the return piping; installing closing sections). The second option involves major repairs and includes additional measures (in addition to those specified above) to insulate the attic flooring and end walls of the building, which can reduce heat losses by 25 %. For both options, automated heating substation equipment was selected. In addition, costs were estimated, economic efficiency was evaluated, and payback periods for each measure were determined. The on-site inspection of exterior wall envelopes and the heating system, as well as measurement of microclimate parameters, provided a means to develop measures to modernize the heating system of academic building No. 7 and evaluate economic efficiency.
