“…Technical and economic indicators of application of the heat supply system based on heat pump depend on the cost of electricity and capital investments for the heat supply system. Further, the cost of electricity decreases with a decrease in temperature of the heat pump condenser and with an increase in temperature of evaporator, but this increases capital costs in the heating system, as the area of heat exchangers, radiators and heaters increases [11].…”

The article provides information about the ring heating system comprising heat pumps. The system is designed as a closed loop, which includes a pump, a thermal energy battery, and a heat pump. The evaporator is connected to the system of water intake from the well and the cooling system of air inside the greenhouse. The resulting thermal energy is consumed for the needs of heating and watering the greenhouse complex. We present a method for determining the dependence of the net present value on the temperatures in supply and return pipelines and temperature of low-potential heat source. The main economic indicators of the implementation of this system on a typical block greenhouse in the city of Tyumen are determined.

In this article a mathematical model for thermal protection level analysis is developed. It is based on the consumption rate of primary energy. It allows to calculate the relevant thickness of the selected insulation material under any climatic and economic conditions with any constant layers of building envelope taken from structural considerations. The key factors influencing the model are also evaluated. The main factors to influence the energy model are the region degree-days and the energy consumption rate for the production, transportation and installation of the insulation material. The following results were reached: this approach requires the data, which sometimes has no public access, provides us with an objective assessment criteria when comparing the level of building thermal protection in different countries.

“…For other types of energy-saving measures, annual savings can be obtained based on the analysis and evaluation of energy-saving design solutions [8][9][10][11][12]. The area where it is possible to quickly reduce the amount of fuel consumed and as a result, energy consumption and emissions into the atmosphere -it's housing, which according to various estimates consumes 30 to 40% of all energy [13][14][15]. To do this, it is sufficient to increase the regulatory requirements for the level of thermal insulation [14], to improve the degree of building automation when adjusting the parameters of the heat transfer fluid at the building entrance, to install exhaust heat heat recovery systems [16] and more efficient heating systems.…”

In this article the technique of determination of payback period of investments taking into account capital costs and economy of means at the expense of implementation of energy saving actions for warming of external protecting designs is considered. Presented in the article the method of assessing the return on investment in the implementation of energy-efficient solutions of facade insulation is only evaluative. For more accurate calculations it is necessary to take into account the discount rate. Nevertheless, the main factors that have a positive impact on reducing the payback period of investments in the renovation of facades are identified. Only an integrated approach to improving the energy efficiency of buildings can not only reduce the cost of operation of buildings, but also provide a reduction in the payback period of investment in the implementation of energy efficiency measures.
