The economically expedient thermal defense оf building with different heating sources

In this paper, we consider the heating sources employing the method of cash flow. We propose the function of optimization of cash flow taking into account the thermal protective properties of building envelope, heating system, and energy resources cost change, and also cost change of heat source depending on thermal protective properties of the building envelope. In addition, we anticipate the discounting of cash flow and analyze the expedience of the abovementioned factors.
