Abstract

Thermal insulation materials used in external enclosing structures, depending on their basic properties, design solutions implemented with their help, the quality of their manufacture and installation, and taking into account the peculiarities of the operating mode, can perform their functions with varying efficiency. This can significantly affect the heat consumption of building heating systems. The paper presents the result of an ongoing experiment to assess the energy consumption of buildings depending on the type of structure and characteristics of their external fences. The test results confirmed the existence of a connection between the intense wind impact on the facade of the building, the air permeability of the enclosing structure and its individual constituent layers and the parameters of the air heating system.
