Abstract: Chambers are the outward atrium spaces of super high-rise buildings.The location and size of different chambers may influence building's internal ventilation.This paper discusses the possibility of improving the natural ventilation inside super high-rise buildings by using the stack effect of chambers in the transitional seasons.By taking the southward contact-style chambers in Guangzhou region for samples,a simplified concept model is constructed,and the internal wind velocity as well as the PMV-PPD ( Predicted Mean Vote and Predicted Percentage of Dissatisfied) values is calculated and analyzed with the help of typical ventilation simulation software.The results indicate that,by setting reasonable chamber height and by adjusting the location and size of chamber s inlet and outlet,most buildings may encounter natural ventilation stably in the transitional seasons,and the internal thermal environment can be maintained within a comfort range for human beings.

Key words: building chamber, super high-rise building, natural ventilation, simulation
