The problem of energy saving in the construction industry involves the installation of additional thermal insulation of enclosing structures. But the thickness of the exterior wall structure has a limit. After a certain thickness, the monetary cost of insulation will grow more slowly than the amount saved on heating. On the other hand, a large chain of participants in energy-saving investment projects (IEP) leads to a significant payback period. It is proposed to use the technology of internal insulation of external walls with a minimum number of participants in the IEP. The calculation of the economic effect is given. The IEP assessment should be carried out taking into account energy consumption throughout the entire life cycle of the proposed building structure.

Keywords: energy saving, energy efficiency of structures, discount rate, energy service.
