Is There a Need to Enclose Elevator Lobbies in Tall Buildings?



Richard W. Bukowski


In recent years there have been several proposals submitted to model building code organizations to require enclosure of elevator lobbies that restrict the movement of fire smoke via hoistways to other parts of the building. NIST is involved with a consortium of industry (elevator and fire alarm), codes and standards developers (NFPA, ICC, ASME, ) and other interested parties (US Access Board) to develop and implement protected elevators for fire service access and occupant evacuation (including assistance to people with disabilities) that includes elevator lobbies as an integral component. Thus NIST was asked by GSA to determine the conditions under which enclosed elevator lobbies were needed and where they were not.
