A new approach has been developed and implemented to quantify thermodynamic losses, their cost, environmental friendliness, investment costs, and anthropogenic impact that can be eliminated in system components, without the need to introduce theoretical or ideal processes. A new approach has been developed and implemented to identify and quantify opportunities for reducing investment costs and anthropogenic impact on the environment in the process of manufacturing system components due to mutual influence and increasing their thermodynamic efficiency. A complex of mathematical models of heating and cooling systems of buildings with low energy consumption was developed and implemented on the basis of the studied TNU, methods and means (based on EnergyPlus, MathCad, Maple, Matlab, CoolProp, Refprop, Python, Google Colab) of implementing these models taking into account the proposed criteria of exergy assessment and with the use of modern information technologies (cloud calculations, digital doubles, etc.). The structures, parameters, and modes of operation of the studied heat and cold supply systems are substantiated, taking into account non-stationary processes.
