Abstract
<p><strong>Purpose</strong>. Investigation of the effectiveness of application in the heating systems of administrative, residential, industrial and other buildings of automated thermal management systems for premises using the «smart home» technology<strong> Methods.</strong> Analysis and synthesis of information, mathematical modeling of the heat supply process of a building, statistical data processing, a computational experiment to assess the effectiveness of the use of «smart home» technologies in heat supply systems. <strong>Results.</strong> A natural object was selected and investigated for the introduction of energy-saving technologies − a 3-storey fragment of the O.M. Beketov National University of Urban Economy in Kharkiv administrative building with a total heated area of 225,3 m<sup>2</sup>; investigated: structure, principle of operation, efficiency of the use of an automated control system for thermal conditions of the premises - HERZ Smart Comfort. <strong>Conclusions</strong>. The efficiency of using the HERZ Smart Comfort system was assessed according to the following criteria: the relative and absolute values of the decrease in thermal energy for heating a building - a natural object, the reduction in atmospheric emissions of carbon dioxide - CO<sub>2</sub>, and the economic efficiency from saving thermal energy.The heat loss calculation was performed at round-the-clock temperature in premises +18 ° C for average monthly outside air temperatures in Kharkov during the heating seasons 1981-2016. It has been established that the use of «smart home» technologies allows reducing the costs for heating a natural object during the heating season by 16.6%, which is 4709 kWh and leads to a reduction in CO<sub>2</sub> emissions from the production of heat in the amount of 0.95 tons/year; The economic effect in this case is 6430 UAH.</p>
