Chapter 1 Smoke control overview
more information about elevator shaft smoke control, refer to Klote, J.K., and Milke, J.A. (Design of Smoke Management Systems, 1992).
Atrium smoke control
Atrium smoke control uses buoyancy to manage smoke in
Smoke exhausting technique
The smoke exhausting technique employs fans to exhaust smoke from the smoke layer under the ceiling. Exhausting prevents the smoke layer from descending and coming into contact with the occupants of the atrium (Figure 7). Effective smoke removal requires providing makeup air to the space. Makeup air replaces the air that is exhausted by the fans. If makeup air is not introduced, the space will develop a negative pressure, which will restrict smoke movement.
