The high-rise building has a total of 10 floors above ground (without a basement), of which four floors are part of the podium and six floors are the tower. One smoke-proof stairwell in the tower is located adjacent to the exterior wall, and each stairwell floor in the tower has exterior windows with an area of 2 m2 each ； There are no operable exterior windows in either the smoke staircase or the vestibule of the smoke staircase in the podium section; which of the following options represents the correct design for smoke exhaust? The answer is B. (A) Pressurized air supply systems are installed in both the smoke-proof stairwells and their vestibules. (B) A pressurized air supply system is installed only in the vestibules of the smoke-proof stairwells. (C) A pressurized air supply system is installed only in the smoke-proof stairwells themselves. (D) Mechanical smoke extraction systems are installed in the vestibules of the smoke-proof stairwells
A. ------------------------------------
(B) A pressurized air supply system is installed only in the antechamber of smoke-proof stairwells; Code for High-Rise Buildings 8.2.2.2 states that it can be activated every five floors, and 8.3.1.2 specifies that it applies to antechambers that do not have natural smoke exhaust”
