Description  is  the concept of smoke at the beginning is selected object of smoke exhaust system (gravity or mechanical).

Then it is determined under what standards will be based on detailed solutions and fire ventilation system in accordance with them are carried out preliminary calculations of its basic parameters such as efficiency and the number of distribution points, indicative of smoke extract and supplementary air supply. The proposed facility is also the division into smoke zones.

The study contains a graphical representation of the results of calculations with the proposed location of smoke curtains which separate between the smoke detector zones and the location of intake-exhaust elements.  Additionally shown is a detailed description of all elements having significant impact on the operation of fire ventilation system, which then form assumptions to carry out computer simulation, verifying the solutions adopted in the concept.
