Abstract

This paper investigates the wind-induced natural ventilation of atrium buildings with several different types of roofs using computational fluid dynamics (CFD) techniques. Three possible flow patterns are identified for an atrium building with a section aspect ratio of unity first and based on this identification the ventilation performance of two common kinds of atrium roof shapes, including triangular type roofs and barrel vault type roofs, are investigated and compared, based on which relevant design guidelines are also developed finally.
