Abstract

Thermal comfort can be a problem for the occupants of many residential buildings, especially for terrace house, in hot and humid climates. This paper therefore presents the results of ongoing research to investigate the distribution of air and temperature flow within the terrace house. The purpose is to achieve thermal comfort level in Malaysia's naturally ventilated residential house using computational fluid dynamics (CFD) method. CFD simulations on the house model allow us to visualize the house's temperature distribution and air flow pattern and velocity. The house's thermal comfort was found to be well beyond the limits set by ASHRAE standards. Simulations were used to investigate the effects of changing the terrace house's wall height. However, there is almost no significant change in the house's temperature distribution and air flow velocity. Result also shows that the use of two air conditioners installed on the front and back walls has significant effects on temperature distribution where the average temperature is 26.3ºC but still higher air velocity which is 3.1m/s than that specified by ASHRAE. Thus, the thermal comfort level in the house is not achieved
