In 2009, a Federal Law No. 261-FZ “On energy saving and improvement of energy efficiency” was accepted. Improving the energy efficiency of heating systems is becoming one of the strategic tasks of the Russian Federation. According to that law accounting and regulation of heating source are obligatory. Noticeable effect of thermal energy saving in heating systems (20-30%) can be achieved by automatically adjusting heat. The most complete and efficient automation task can be implemented with the help of automated district heating substations(ADHS) of buildings with the ability to control heat at the request by customer level, depending on the outdoor temperature. The tasks of reconstruction existing and designing of new energy-efficient ADHS have important economic significance and will be relevant in the coming decades, as the behavior of thermal technological systems of buildings with various changes of internal and external factors should be adjustable and ADHS, being a link between consumers of heat and heat networks allow to meet modern energy-saving technologies, which will obtain low-cost, fast design and technological solutions. Authors of plenty articles say, that as any other technology it should have a universal strict algorithm of design. Unfortunately analysis of scientific-research literature base showed absence of detailed methodologies of ADHS design. Therefore the scientific problem of the research is to develop heat source submission terms depending on the actual climatic conditions and mode of operation of the building.
