The insufficiently and poorly ventilated premises or inappropriately ventilated operation can cause primarily health problems of occupants but also damage to building structures. It is necessary to ensure adequate quality of ventilated area, a healthy environment, the required air humidity and air temperature. On the other hand, it is needed to achieve reasonable energy costs and sufficient air exchange (ventilation rate) under current legislation. To reconcile all of these requirements and then find appropriate solutions and alternatives of ventilation is necessary to evaluate several modes of moist ventilation premises and to choose the best alternative. In the work is carried out analysis of calculation methods to determine the ventilation rate. Is processed the methodology for calculating the ventilation rate of room, by are used the measured values in concentrations of carbon dioxide. Values concentrations of carbon dioxide and ventilation rate are verified by experimental measurements. The methodology is selected for calculating ventilation rate applicable in to Slovakia. The result of methodology is nearest the result from experimental measurements. By the following is determined the methodology for calculating ventilation rate for office.
