【 摘 要 】

As one of the densest population occurred in Johor Bahru, development of a new township become necessary in order to cater this growth. Rapid urbanization is a factor of degradation of environmental quality which may increase surrounded temperature through urban heat island (UHI) phenomena. Therefore, this paper is investigating thermal comfort for a new township, Bandar Dato Onn in Johor Bahru, in order to understand the thermal characteristics of a new township and for further mitigation of UHI phenomena. Surface temperature, ambient temperature and relative humidity have been collected from a terrace house of Bandar Dato Onn. Thermal characteristics with the features of time lag and decrement factors were discussed based on the collected data. The time lag of 5 to 8 hours and the decrement factors of 0.02 to 0.06 were recorded during a five-day measurement. It was concluded that human thermal comfort may not be achieved as the heating, ventilation and air conditioning (HVAC) system needed for bedroom and living room. Passive energy design is suggested to be included in the house in order to have human thermal comfort while reducing the electricity consumption towards sustainable future.
