The project is led by research institute Singapore-ETH Centre, which was established by the Swiss Federal Institute of Technology in Zurich in partnership with the National Research Foundation under its Create programme. It comprises academics from the National University of Singapore, Singapore– MIT Alliance for Research and Technology and TUM CREATE (Technical University of Munich). In addition, there is also a Cooling Singapore Taskforce comprising 14 other government agencies and research institutes, including the Urban Redevelopment Authority (URA) and the Singapore University of Technology and Design.
Together with the URA and the Housing and Development Board (HDB), researchers have begun modelling studies to see how different
mitigation measures can be applied. It has been found that more re ective roofs can achieve up to a 1.29°C reduction in temperature, new developments can change air patterns and increase thermal stress, depending on weather conditions, and void decks at public housing blocks can have a positive impact. More vegetation may seem to cool the place but it is not always the case, as trees can reduce wind speed and increase humidity.
The project has come up with a menu of 86 possible measures spanning seven key areas – greenery, urban geometry, water features, material and surfaces, shading, transport and energy – to help make Singapore’s outdoor environment cooler.
Principal investigator of the Cooling Singapore project Assistant Professor Winston Chow said, “The urban heat island effect has been undervalued previously, and this project aims to bring it to the forefront. There are many bene ts to managing it properly, whether it is in the form of cost savings from using less energy; or indirect bene ts of having more greenery in the city.”
