Science and Facts

Cooling Singapore works on furthering our understanding of the Urban Heat Island effect (UHI) and Outdoor Thermal Comfort (OTC) as it applies to Singapore. Potential strategies that can be used to mitigate UHI and improve outdoor thermal comfort (OTC) are systematically assessed through existing and up-to-date simulation tools that have been inventoried and quoted based on their already known limitations but also strength in urban planning applications.

Key tasks include identifying key actors and agencies as well as knowledge already elaborated for Singapore that can be mobilized in future to reduce heat impacts and issues in the city-state. It also include the evaluation of the UHI determinants (as the anthropogenic heat released from buildings and road traffic), effects, countermeasure and impacts on regional climate and OTC. A modeling approach has been chosen. A particular attention has been paid to energy sources and losses (in the form of heat) in Singapore by sectors and fuel types. Outcomes of these investigations and identified knowledge gaps have been systematically published in the form of reports and guides.
