Today, the issue of energy saving and energy security is of particular relevance both locally and globally. Today, the world is facing an acute problem of saving and rational use of energy resources in order not only to reduce their consumption but also to reduce pollutant emissions. For Ukraine, the issue of energy security has become particularly acute since the beginning of Russia's hybrid aggression. The destruction of energy infrastructure, the threat of disruption of energy supplies, and aggressive actions in the economic sphere are driving Ukraine to improve energy efficiency along the chain from production to consumption and to develop modern energy-saving technologies. According to the European Parliamentary Research Service, households are the largest energy consumers in Europe, with final energy consumption accounting for 28% of the total energy consumption of all sectors. That is why researchers are focused on implementing resource-saving activities through the use of modern energy-efficient technologies in households and buildings, in particular, to reduce transmission and infiltration heat losses. To determine the extent of heat transfer losses, it is common to measure the thermal resistance of buildings on site. These measurements are usually made by analysing the low-density heat flux. To monitor the thermal insulation characteristics of building envelopes and materials used in repair work and establish their actual values, it is extremely important to develop modern monitoring tools and appropriate methods for measuring thermal resistance as the main indicator in assessing the energy efficiency of buildings.

Analyses the current state and regulatory requirements for energy efficiency of buildings in Ukraine and the world Describes methods for assessing the condition of external envelope and detecting thermal failures of buildings Presents natural air exchange in the level of CO2 concentration around educational institutions and residential areas
