| Abstract | In the design process of a residential development, various site planning and building or layout fine-tuning stages would be involved. The unique high-rise, high-density urban context and the hot and humid climate conditions in Hong Kong are important considerations in designing a comfortable and healthy built environment. Building re-entrants are most popular in high rise and high density residential buildings in Hong Kong, partly due to the Building (Planning) Regulations. Windows of the kitchens and bathrooms as well as living or dining rooms are open towards the re-entrants for sources of natural lighting and ventilation. The quality of the air in the re-entrant will determine the quality of ventilation introduced to the indoor. This paper describes some investigations on variation of the dimension of typical I-shaped re-entrant making use of the powerful simulation tools based on computational fluid dynamics (CFD) techniques on the ventilation effectiveness of the re-entrant. The results show the optimum aspect ratio of the dimension of a re-entrant. |
