The influence of architectural and construction parameters of residential buildings on energy efficiency in Russian Federation

Abstract

The article discusses the dependence of the energy saving class of a residential multi-apartment building on various architectural and construction parameters. The study was conducted on the example of a building model for 36 cities of the Russian Federation in various climatic conditions. The calculation of the energy saving class was carried out according to the method of Building Code 50.13330.2012 «Thermal insulation of buildings». The analysis of this technique in relation to the architectural and construction components of the building is given. It is shown that the traditional approach to the design of residential buildings without the use of additional energy saving measures allows to achieve an energy saving class at level «B» (above -30 % of the base value) regardless of the height of the building. A significant change in the energy saving of the building with a different glazing-to-wall ratio is shown. It is proved that the additional insulation of the building envelope does not lead to an effective increase in energy saving. The calculation showed that heat recovery using a mechanical ventilation system is an important factor in increasing the energy efficiency of residential buildings.
