Smoke Control by Systematic Pressurization
An experimental investigation of smoke control in high-rise buildings by the 'Systematic Pressurization' concept is presented here. This concept of smoke control involves the utilization of a modified building air-handling system. The building is generally divided vertically into several horizontal smoke control zones, each containing a predetermined number of floors. Upon smoke alarm the air-handling system is programmed to switch to smoke control mode by providing 100% exhaust to the smoke zone and 100% supply to the other zones. The idea is to simultaneously exhaust smoke from its zone of origin, and prevent smoke propagation to the other zones by pressurization. Examples of the zoned or systematic pressurization smoke control concept are the Seattle and Chicago Federal Buildings. An extensive series of experiments, using the sulfurhexafluoride smoke simulation system, were performed to evaluate these buildings. During the experiments, complete stairwell and elevator shaft pressure profiles under normal and smoke control operations were also obtained. The effectiveness of the smoke control system as implemented in these federal buildings is discussed in the light of normalized sulfur-hexafluoride concentrations and the pressure profiles.
