Formulas in this program are created to determine equilibrium between all thermal gains produced by industrial processes within a bulding as well as air flow exhausted by the ventilation system. Based on this principle, the program is not intended to calculate air exhaust used to prevent thermodinamic disasters such as fires or an explosion blast in the case of accidental discharge of flamable gases. This program requires the user to possess and apply engineering knowledge and to understand physical phenomena occurring in the natural ventilation of buildings. The results of the program’s calculations will always correspond to the adopted criteria and the input data which have been entered, for which only the user is responsible.

Program VENTOS requires MS Net Framework 2.0 to run on your PC (or newer, to download from internet).

Clicking the “SEND” button implies that you accept and agree to these provisions of the licence agreement.
The VENTOS program will be sent to the e-mail address given above within two working days.
