Analysis has been made of the methods of improving the energy consumption efficiency of buildings by controlling the heat consumption by various devices (including individual heat points) without and with account for the air temperature control in a room (presence of feedback). Particular consideration was given to the low-cost method of energy saving by decreasing the air temperature in the absence of people, which at present is used inadequately, although its potential can reach 15–20%. The investigations carried out by us have shown that to effectively regulate the energy consumption with the aim of its saving, it is necessary to introduce feedback between the rooms of the building and the individual heat points. Analysis of the thermal state of an old office building with a low energy-efficiency has enabled us to develop methods for decreasing energy consumption by up to 4% for district heating and up to 10% for individual heating.
