Life safety devices within high-rise buildings have changed in the past seventeen years. After 9/11 there was a clear understanding that we needed a better mechanism to get people out of a building safely while allowing first responders to work without fear of being trapped. New codes have now made stair pressurization a requirement in any high-rise regardless of any supplemental life safety systems. This presentation looks at lessons learned from NYC projects and the special considerations they present and explores why this system is so complicated to understand and test – quality, equipment, logistics, challenges, and solutions. This session focuses on the advanced control of outside air, specifically as it applies to building pressurization systems and outside air economizer control.
