Main part. At present, all over the world, including England, Germany, Denmark, In natural
energy in Sweden, USA, Russia and other countries In order to save resources and design energy- efficient buildings, various fog, energy as external barrier structures of buildings effective constructive solutions are being used. For example, external heat to increase the thermal protection of the barrier structure by protecting the insulation layer from the inside surface of the barrier. Bo the main drawback along with the computational side of the constructive solution consists of the following. That is, heat with a high resistance to heat transfer heat when the insulating material is built from the inner surface of the outer wall condensate at the boundary between the outer wall and the insulating layer moisture may form. Such a situation has been observed in practice and theoretical research. To prevent this, the outer layer of thermal insulation It is recommended to build a barrier structure from the outside The solution can also be used in thrombus-walled buildings. In Uzbekistan external barriers to increase energy efficiency of buildings heat protection of constructions in Журнал «Студенческий вестник» № 7 (152), часть 3, 2021 г. 75 accordance with the requirements of QMQ 2.01.04-97 * 3-4 times. This normative document is currently being adopted, heat the exterior walls, roof covering, window doors and lanterns how many times to increase protection. Besides in the process of thorough and current repairs of existing buildings the need to increase the thermal protection of their external barrier structures listed. Here are the things to look for when selecting yours. The total heat transfer resistance of external barrier structures, 2a, 2b or 2v according to the given degree of thermal protection of the building must be greater than or equal to the heat transfer resistance given in the tables. A solar cell that absorbs sunlight absorbs solar radiation and converts it into heat energy. Such heating systems are inferior to the method of using solar radiation temperature is divided into passive and active heating systems. A device that converts solar radiation into heat is a helio device used in the building itself or in any building structure, passive low called a heating system with heated sunlight.
