Energy Efficient Design Solution for the Interface Node Between the Floor Slab and the Wall

Abstract

AbstractThe most of the housing stock in the Russian Federation is located in difficult climatic conditions. In such a situation, an important place is occupied by issues related to the energy efficiency of the enclosing structures of residential buildings. In Russia, in the field of civil engineering, a significant proportion of buildings erected using monolithic technology do not meet modern thermal protection requirements. Improving the energy efficiency of such buildings at the design and modernization stages is an important scientific and practical task. The article proposes innovative design solutions aimed at increasing the thermal protection of the building envelopes and the parameters of the microclimate of the premises, which are various options for the joints of the floor disc with the wall. The proposed solutions can be used in the renovation of existing buildings, as well as in the design and construction of new monolithic residential buildings. The issues of heat transfer processes in the junction of the floor disc with the wall are considered. For the studied fragments of the enclosing structures, mathematical models are built based on the heat conduction equation. The results of computational experiments in the ANSYS software package are presented.
