Abstract: One of the ways to reduce the uses of heat and electricity energy in agricultural buildings and to improve microclimate is the increasing of heat isolation of the building and using effective building materials for constructions of barrier. It has been known that between outdoors and soil (that is in structure’s zone) and between the lodgment’s air, intense heat interchanges are through the floors to the soil as well as through foundations. These interchanges have a huge influence on the microclimate of the whole building. When microclimate is optimal, the animal efficiency may grow up to 30%. When microclimate is incorrect, 15-20% of animals (especially young ones) could be lost because of diseases, their weight decreases to 25% and 15-20% of the feed is overdraft. The microclimate of the cowshed depends on building constructions, the temperature state of the building, the temperature of inside surfaces of barriers very much. The influence of the ground soils below the cowshed building over the temperature regime of the traditional floor surface is analyzed in the study. Three borings for temperature measurements have been arranged outside and in the inside room of the building. Temperature variation curves (for various seasons) of the ground surface at the floor level of cowshed building have been made. The investigation of temperature variation of period one year at floor surface has been carried out. The character of variation of outside temperature (during the whole year) for the base of cowshed building and soils in its surroundings was produced. Experimental temperature measurement data shows that a significant influence on the internal base ground temperature field has - heat radiated by animals, that attaches itself not only in the air, but also to the base ground through bearing housing floor.[...]
