Air temperature Distribution of Different Features and Urban Typology Blocks of Putrajaya City (Malaysia)

Abstract

The study examines the effects of heat islands on Putrajaya City and evaluates the planned city features effect since climate policies were not deliberatively considered during the planning process. The aim of this study is to explore the effect of air temperature on the different urban forms and residential areas in the completed construction precincts of Putrajaya Boulevard. The investigation was performed using a mobile survey method with a data logger three times a day, during the morning, noon, and afternoon time, for three days during the hottest month in July 2012. It was found that there is no significant difference in variation of the air temperature between the different city features, and urban typology blocks, and the maximum air temperature was 37 °C. Hence, the temperature has remained constant since before the city was built. Therefore, the climate aspect was not considered during the planning process for reducing the temperature and improving environmental comfort. It is, therefore, necessary to establish a strategy and policy that will reduce the high air temperature before the master plan is completed.
