Abstract

The research was conducted for three types of houses, including a panel house built before 1991, a brick house built in 2006, and a brick house built in 2022. It was established that the temperature difference, which is decisive when assessing the sanitary and hygienic condition of the premises, does not exceed the normative values for buildings built after 2006. In the building since 1991, the sanitary and hygienic indicators of the heated room deteriorate when the outside air temperature drops below −3 °C. At the same time, the fulfillment of the first condition of comfort in the room occurs at indoor air temperatures higher than the standard value, therefore, under the calculated conditions, residents feel discomfort when staying in such a room.
