Foreign innovative technologies in the field of increasing the energy efficiency of buildings and their engineering systems

Abstract

About 36% of greenhouse gas emissions in the EU are accounted for by the construction of buildings and the use of energy in them. To reduce energy consumption in buildings, it is necessary to introduce more energy-efficient technologies. However, there are barriers to the introduction of energy-efficient technologies. Inertia, risk, access to capital and lack of knowledge are considered the most noticeable obstacles to the introduction of energy-efficient technologies. In order to expand the implementation of energy-efficient technologies in buildings, it is necessary to expand knowledge throughout the industry, and stakeholders need to consolidate at all stages of creating an energy-efficient residential environment. Reducing greenhouse gas emissions is of paramount importance to mitigate the effects of global warming. To reduce emissions from buildings, it is necessary both to reduce emissions during the construction phase and to reduce energy consumption during the operation of the building. Energy consumption during the operation phase of a building depends on several different factors, such as the behavior of residents, the thermophysical properties of the building, the technical details of the structure, the climate, as well as the maintenance and quality of heating, ventilation and air conditioning systems. For buildings to become more energy efficient, it is necessary to take into account all these aspects. The article analyzes the experience of the USA and the EU countries, which are actively developing innovative developments in the field of energy-efficient construction and modernization of existing buildings in order to increase their energy-saving resource.
