Fire Safe North America worked with Mike Ferreira, VP of Jensen Hughes, to complete a multi-phase research and technical paper based on the study entitled, “Impact of Stairwell Pressurization on Elevator/Ventilation Shaft Stack Effect.” This multi-year study was the single most important technical contribution for the disapproval of code change G200 in the Group A IBC Code Change Cycle, which would have eliminated elevator lobbies in high-rise buildings.

The approval of this code change would have been the pre-cursor to other changes to rely on sprinklers for management of the vertical migration of both smoke and fire. The research paper that FSNA sponsored has been vigorously peer-reviewed and published online in January 2016, in Fire Technology magazine.
