Improvement of technology of thermal insulation of buildings

The relevance of research is due to the fact that at present, modern standards for saving thermal energy and thermal protection of buildings are focused on the use of a very limited set of solutions to reduce energy consumption, which do not always meet the specific conditions of construction and are often very expensive. A technique for studying the effective insulation of building envelopes is proposed, taking into account the relationship between structural, heat engineering, regime parameters and economic indicators. The goal is to determine the optimal value of the thickness of insulation by the heat-insulating material of the object, taking into account the thermal energy supplied to it. In the study, methods of mathematical modeling of heat transfer, an optimization problem were used. An experimental study is presented, showing the possibility of applying the technique of technical and economic optimization of thermal insulation of building envelopes. The result of the study is to reduce the cost of heat losses through building envelopes and electrical energy for the regulation of the “heating, ventilation and air conditioning” system. The conducted studies testify to the expediency of using the proposed developments, which contribute to determining the optimal thickness of insulation with heat- insulating material of the walls of objects, finding the minimum reduced costs, and an advantageous choice of a method for regulating the supplied thermal energy.
