Thermal imaging survey of general education institutions in Moscow

Objective . The aim of the study is to determine the causes of the formation of an uncomfortable microclimate in the school premises on the 1st floor (option 1), as well as to examine the school facade (option 2) using thermal imaging and temperature measuring devices inside the building. Method . Аssessment of the building's structural design; external visual inspection of the building's external enclosures; thermal imaging survey using Testo 868 and Testo 870-1 thermal imagers; additional measurements of indoor air temperature and recording of meteorological conditions using a Testo 435 multifunctional measuring device with an air temperature probe; processing of the obtained thermograms. Result . As a result of the measurements, thermograms were obtained inside the problematic rooms in the first school and on the facades of the buildings in the second school, as well as the values of the internal and external air temperature. Conclusion . Thermal imaging revealed defects in the school facade according to option 2 and reasons for the uncomfortable stay of people on the 1st floor of the school according to option 1. Insufficient thermal protection of buildings was revealed due to poor insulation of enclosing structures, uninsulated entrance doors without a vestibule, which leads to condensation of moisture on the inner surface of the outer wall and door, as well as uncomfortable microclimate conditions in the premises. It was revealed that sunny weather in the cold season affects thermal imaging and does not allow measurements to be taken correctly, even taking into account that the amount of thermal energy from solar radiation at this time of year is insignificant.
