Simple Estimates of Combined StairWell / Elevator Egress in Buildings



Paul A. Reneke, Richard D. Peacock, Bryan L. Hoskins


This report is part of this effort to develop requirements for the use of elevators in tall building evacuations. It describes a simple tool to estimate combined stairwell / elevator egress time from buildings. It is based on methods developed in the Society for Fire Protection Engineers (SFPE) Handbook for egress using stairwells and the work of Klote and Alvord on modeling elevator evacuations. A description of the theory and use of the model follows.
