Abstract: Enlargement of the thermal isolation of external barriers is the simplest and the most effective way to reduce the waste energy on the heating aims. Unfortunately, inappropriate analysis and luck of coordination while performing thermomodernizational work, negatively influences the microclimate in such objects. The size and the distribution of the intake openings has been decisive for proper functioning of gravitational ventilation and warranty for the proper parameters of internal microclimate. Even small works done on thermomodernizational ventilation may influence the quality of work of the whole system of gravitational ventilation. These work should be carefully designed, planned and carried out efficiently.
