Calculation of the Payback Period for Energy-Efficient Building Envelope

The purpose of this paper is to compare energy consumption of residential house with typical wooden frame structure and energy-efficient double framing structure of the external wall and to calculate difference of construction cost with application of both technologies. Research method is based on simulation process in eQUEST software that provides detailed reports on all aspects of building energy-efficiency and allows to determine amount of consumed energy. With help of simulation results produced by eQUEST it is possible to calculate payback period for energy-efficient building envelope based on market prices of construction process.
