Abstract:
Piloti is commonly used in tropical and subtropical climate zones to get high wind velocity and create shadowed areas in order to optimize the living environment of residential blocks, but there are few studies to reveal the influence of piloti on the radiant environment of residential blocks systematically. Taking the city of Guangzhou as an example, using 3-D Unsteady State Heat Balance Radiation Calculation Method, this paper shows that the mean radiant temperature (MRT) under piloti area increases with the increase of piloti ratio, and especially when piloti ratio is equal to 100％, the MRT increase trend becomes sharp. The MRT of exposed area decreases with the increase of piloti ratio, especially when piloti ratio reaches 100％, the decrease trend of MRT becomes sharp, which offers the reference for the study on piloti design in subtropical climate zones and further research on living environment by CFD simulation in residential blocks.
Key words:  piloti  mean radiant temperature  3-D unsteady state heat balance radiation calculation  residential block
