Abstract

With more urbanization in an island country of limited land area like Singapore, Urban heat island (UHI) is becoming a widely recognized phenomenon which is causing outdoor thermal discomfort to pedestrians and also causes high energy consumption by buildings. For a prospective residential development in Singapore, computational fluid dynamics simulation and temperature mapping have been conducted to highlight the urban parameters that should be considered to mitigate the adverse effects of UHI effect. Simulation shows higher day time and night time temperature at zones with exposed wall surfaces and pavements due to high sky view factor and higher storage of heat. Creation of more openness on ground and planting trees in such exposed spaces shows reduction in maximum temperature during day by about 2.2 °C with increase in wind velocity as well. Improvement of outdoor thermal comfort from warm to neutral has been obtained with improved orientation of buildings and introduction of urban greenery.
