THE ROLE OF MASSIVENESS OF BUILDING STRUCTURES IN ENSURING THE THERMAL REGIME OF THE BUILDING

Abstract

The article considers the relevance of the issue of the influence of massiveness of structural elements of a building on its energy saving in the context of modern requirements for energy efficiency and sustainable development. The ability of massive structures to accumulate thermal energy, reduce the amplitude of daily temperature fluctuations in the premises and reduce peak loads on heating and air conditioning systems is analysed.

The main physical parameters of building envelopes that have a significant impact on their thermal properties and energy consumption are considered. The thermal performance of building envelopes in accordance with EU standards and current national standards is summarised.

A comparative analysis of buildings with different types of building envelopes is carried out, in particular, in terms of heat loss, structural inertia, microclimate stability in different regions and with different types of climatic conditions. The influence of climatic conditions and building orientation on the feasibility of using massive solutions in the design and construction of buildings is considered.

The main characteristics of current and popular wall materials and their thermal properties, which are used in Ukraine and are leaders in the construction market, are considered. The key factors influencing the choice of the type of construction in terms of energy saving are highlighted: functional purpose of the building, mode of operation, materials of structural elements, availability of energy storage systems and economic feasibility.
