Abstract
A high-rise building has a stairwell, an air supply shaft, inlet openings connecting the air supply shaft to the stairwell, and a pressure system for keeping the stairwell free from smoke. The stairwell is vertically divided into several partial spaces. The separation is performed by at least one partition. Each partition has a door enabling a passage from one partial space of the stairwell into an adjacent partial space.
