THE FEASIBILITY OF REALIZATION NONCONVENTIONAL AND RENEWABLE ENERGY PROJECTS FOR RESIDENTIAL BUILDINGS WITH THE CONSIDERATION OF REGIONAL FACTORS
The method of feasibility study of technical solutions for efficient using of energy resources in houses has been considered in the article. The effectiveness of implementation of renewable energy sources depends on regional factors. The pricing, the availability of gas distribution networks, and other local conditions are influenced on the economic criteria, such as net discounted profit, payback period, costs shown. The examples of calculation of economic criteria are given based on a practical methodology for the economic evaluation of technical solutions. Payback period for renewable energy of the house has determined. The cost of the equipment influences on economic criteria. Stable prices for domestic equipment will reduce capital costs.The stages of realization of technical solutions for effective implementation of unconventional and renewable energy sources have been considered. Rational using of renewable energy sources with traditional methods of heat supply provides high reliability and economic efficiency.
