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.

research work has contributed to the development of a
simulation based computer software for the analysis of indoor air
quality and ventilation in buildings. He is the Principal Investigator for a
number of on-going research projects funded by NUS and government agencies.
These include Natural Ventilation Studies of Public Housing in Singapore, A Study of Rooftop Gardens in Singapore funded by NParks and
A Study of Urban Heat Island in Singapore funded by BCA.
