The purpose of this work is to assess the thermal comfort of a block-modular building on the construction site. The experimental studies for determining the thermal conditions of the cabins in the winter and the summer time of the city of Zhengzhou was carried out at different locations of the modular house made of sandwich panels for determining the category of living comfort. The variations of air temperature and relative humidity in the cabin were analyzed. The difference between outdoor and indoor air temperatures, as well as the changes in air temperature and heat flux on the internal surface of the different walls of the building by their location relative to the cardinal directions were considered. Reasons for decreasing the comfort in the room and the attenuation of the experimental amplitude of the outdoor temperature fluctuations in the enclosing structure as well as the thermal properties of enclosing structures of the block-modular building under different climatic conditions were studied. It is shown that it is necessary to take into account the reflection of heat inside the premises and their ventilation when designing enclosing structures of mobile buildings. It is revealed that in the winter period for energy saving it is necessary to increase in addition thermal characteristics of the western wall of domestic buildings.
