Energetic parameters of a low-rise living building constructed with materials of the organic origin

Aim. One of the main problems of the energy conservation refers reducing the heat consumption in Civil Engineering. We propose a new method to determine energetic parameters of residential buildings. As an illustrative example, a low-rise building constructed with materials of the organic origin and located in Kyiv is considered. Methodology. Heat consumptions through fencing structures, for the supply and infiltrated air are determined depending on the daily average outdoor temperatures. Changing of the climate parameters within the year are described by expansions into Fourier series. Results. Thermal properties of the fencing structures are analyzed. The energy consumption of the building is determined considering the heat recovering from the exhaust air and the season variations of the heating regime. Novelty. The developed method gives a possibility to take into account the changing of the climate parameters during the heating period, which is not possible in the framework of commonly used engineering approaches. This enhances the accuracy of the results, in particular, for “passive houses” with enormously low heat consumption. Practical importance. Practical recommendations for the optimal design of the thermal insulation of buildings are given. The obtained results allow one to evaluate precisely the energetic parameters of the energy efficient buildings.
