Urban Heat Island is a phenomenon where the temperatures in the city are higher than the suburban rural areas. This presentation will focus on discussing a current on-going research project to investigate the severity and impact of Urban Heat Island in Singapore. The investigation include the utilization of satellite images to obtain surface temperature distribution of various regions of interest; trend analysis of climatic data; macro and micro climatic modeling of housing estates and CBD areas; and the exploration of potential measures that could be utilized to ameliorate the effects of Urban Heat Islands. Specifically, the effectiveness of introducing vegetation on rooftops of buildings to lower energy use for cooling and mitigate UHI effect will be examined through a series of field measurements.
