Basement spaces in many university buildings because of the worse microclimate conditions are most commonly used for warehouses in which workers or students cannot be. In many buildings there are also problems occurring with the underground moisture that penetrates from the surrounding terrain into the external walls, which thus become wet. The aim of this paper is to show the possibility of microclimate improvement in the basement room by forced ventilation, so that it is possible to use this room for the purpose of teaching and research laboratory activities. Due to the need of permanent intensive ventilation to exhaust the chemical pollutants and supply the fresh air, the ventilation system is designed to achieve the energy savings during the winter by means of heat recovery from the exhausted heated air into the cold incoming fresh outdoor air. This paper summarizes the experience in use of this ventilation system with heat recovery, which could enable to solve well similar problems in other underground buildings.
