Abstract

The issues of saving energy resources are of particular relevance for the regions of Russia with an extremely cold climate. The increased air pressure difference in winter and the presence of volumetric cold bridges in the form of pile and column grillages, basement slabs and concrete block masonry often leads to a violation of the temperature regime of the first floors of multi-storey buildings with a monolithic reinforced concrete frame. Thermal analysis of fragments of basement floors in areas with columns and grillages with additional thermal insulation from the outside was carried out. The low efficiency of the external thermal insulation of the basement elements of the operated frame-monolithic buildings is shown.
