Abstract: A method for measuring pressure differences in different premises of a building, in which the pressure difference is measured using one or more sensors (2) that measure absolute pressure. The measurement results obtained from the sensors (2) are combined with information on the efficiency of the ventilation of the building, and the pressure difference caused by ventilation is mathematically separated from the measurement result by making use of information on the ventilation efficiency at any one time.
