This Guide provides information on special topics that affect the fire safety performance of very tall buildings, their occupants and first responders during a fire.  This Guide addresses these topics as part of the overall building design process using performance-based fire protection engineering concepts as described in the SFPE Engineering Guide to Performance Based Fire Protection. This Guide is not intended to be a recommended practice or a document that is suitable for adoption as a code. The Guide pertains to “super tall,� “very tall� and “tall� buildings. Throughout this Guide, all such buildings are called “very tall buildings.�  These buildings are characterized by heights that impose fire protection challenges; they require special attention beyond the protection features typically provided by traditional fire protection methods. This Guide does not establish a definition of buildings that fall within the scope of this document.
