Features of calculation of heat consumption for heating energy-efficient buildings

Abstract

In connection with the implementation of the energy saving program in construction, the regulatory requirements for thermal protection of enclosing structures have significantly increased, which has led to the construction of energy efficient buildings with low energy consumption. The article presents the results of the heat engineering calculation of an 8-storey residential building under construction in the city of Samara. The outer walls of the first two floors are insulated with a facade system, the upper floors are made in the form of well masonry, as a heater for which thermal insulation is designed in the form of a cassette of three sheets of foam foam, mounted on a wooden frame. An assessment of the energy efficiency of the above-mentioned building was made and an analysis was made of the influence of the reduced resistance to heat transfer of the outer wall on the value of the specific heat consumption for heating the building, as well as increased heat loss in window slopes on the energy consumption in a residential building.
