INFLUENCE OF BUILDING MATERIALS ON THE THERMAL INERTIA OF BUILDING CONSTRUCTION

Abstract

One of the important, but insufficiently studied factors affecting energy efficiency is the thermal inertia of building envelopes. Recent studies confirm the key role of thermal inertia in increasing the energy efficiency of buildings, especially in a changing climate and increasing demands for sustainable construction. This paper examines various building materials from the point of view of their inertial properties. Insufficient consideration of thermal inertia can lead to inefficient use of passive heating or cooling, and energy overconsumption by heating, ventilation and air conditioning systems. Particular attention is paid to the use of thermal insulation and structural materials in building walls. The purpose of this paper is to conduct a comparative analysis of thermal insulation and wall building materials to identify their impact on the thermal inertia of building envelopes. To analyze the thermophysical characteristics of the main thermal insulation and structural materials used in building envelopes. The obtained data allow us to state that the thermal inertia of the structure is largely determined by the physical properties of the structural layer (wall materials), primarily its density and specific heat capacity. To ensure a comfortable microclimate in the premises, it is advisable to use wall materials with high thermal inertia. The obtained results can serve as the basis for modeling temperature changes in walls with different material options for a more accurate assessment of their real energy efficiency.
