Evaluation of cool roof and vegetations in mitigating urban heat island in a tropical city, Singapore
A numerical study with a weather research and forecasting (WRF) model at 300-m resolution shows that Singapore’s canopy-layer UHI intensity has a strong diurnal cycle, peaking in early morning and keeping almost constant during late night and early morning. The modeled ensemble peak UHI intensity is 2.2 C and it can reach 2.4 C during early morning in the intensive industrial region in west Sin...
متن کاملThe effectiveness of cool and green roofs as urban heat island mitigation strategies
Mitigation of the urban heat island (UHI) effect at the city-scale is investigated using the Weather Research and Forecasting (WRF) model in conjunction with the Princeton Urban Canopy Model (PUCM). Specifically, the cooling impacts of green roof and cool (white/highalbedo) roof strategies over the Baltimore-Washington metropolitan area during a heat wave period (7 June–10 June 2008) are assess...
متن کاملUrban Heat Island: Causes, Effects and Mitigation Measures - A Review
High temperature in the city centers than its’ surroundings known as the Urban Heat Island (UHI) effect, which is causing discomfort to the urban dwellers in the summer time is gaining much attention around the world because the world is getting urbanized as it advances in technology. Alterations of surface area, improper urban planning, air pollution, etc. are causing this increasingly growing...
متن کاملComparative microclimate and dewfall measurements at an urban green roof versus bitumen roof
Urban green roofs are discussed as a local climate adaptation measure to limit surface warming and increase evaporative cooling by vegetation in urban environments. A five month measurement campaign was conducted to observe surface and air temperatures as well as dewfall dynamics and amounts on an urban green and co-located bitumen roof. Measurements were performed in the period from August to ...
متن کاملAccumulated snow layer influence on the heat transfer process through green roof assemblies
A green roof can reduce the peak thermal cooling loads and reduce the building energy consumption during the summer. It is also necessary to understand the thermal performance of these green roof assemblies during the winter when affected by an accumulation of snow on the rooftops. This study presents an experimental investigation and discusses the snow influence on the heat transfer processes ...
