| Title of the article | Increasing the energy saving class of residential buildings due to architectural, structural and other parameters |
| Abstract. | Problem statement. According to the Decree of the Government of the Russian Federation No. 1853-r dated September 1, 2016, the share of residential buildings with high energy efficiency should continuously increase up to 30 % by 2025 in relation to the level of 2015. The requirements for energy saving in buildings are constantly tightening, which means that it becomes more difficult to achieve high energy efficiency in buildings. At the same time, the resource for improving the energy efficiency of residential buildings is also quite limited. In this regard, an urgent task is to assess the possibility of achieving high energy saving classes in a residential building in the Russian climate by architectural, structural and engineering measures, which is the goal of the present study. To achieve this goal, the work solved the tasks of assessing the impact on the energy saving class of a residential building of the main architectural and structural parameters of the building, as well as assessing the potential for increasing the energy saving class through the use of a mechanical supply and exhaust ventilation system in a residential building. Results. Calculation and analysis of energy saving parameters was carried out for a single-section residential building with different number of storeys, facade glazing coefficient and resistance to heat transfer of enclosing structures, as well as the use of heat recovery in the ventilation system. The study was conducted on the example of a building model for 36 cities of the Russian Federation in various climatic conditions. It is shown that for a one-section residential building designed without the use of additional (in excess of the normative) energy-saving measures, the energy saving class does not rise above "B", regardless of the number of storeys of the building. It has been proven that additional insulation of enclosing structures does not lead to an effective increase in energy savings. Conclusions. The significance of the obtained results for the construction industry lies in the fact that it shows the necessity to include additional (above the normative) energy saving measures in the projects of multi-apartment residential buildings in order to achieve high energy saving classes. |
