Codes & Standards Discussion Forum 

Welcome to the ICC Codes & Standards Discussion Forum

The Code Council has revisited how best to provide an online, professional Discussion Forum and area within the website that has a sense of community – where Members and nonmembers can provide input and exchange ideas with their peers in the industry. The new Codes & Standards Discussion Forum does just that, as it allows Registered Website Users and ICC Members to discuss the I-Codes in an online community.

elevator pressurization and venting is done all the time in high rises. the vent basically allows ''pressure'' to release as the elevator car moves up and down. this vent can be closed during pressurization, or partially closed. the pressurization, typically with the use of fans introduced into the shaft (serving no other spaces) is usually greater than the relief vent, thereby accomplishing positive pressure.

i wouldn''t see an elevator as the type of space 1202.2.7 is referring to. if you read the paragraph it seems to indicate useable, or habitable, space without actually saying that...''or similar rooms''. i don''t see an elevator shaft as a room, or anything remotely similar to what is listed in the paragraph.
