Effect of pavement materials on surface temperature in Presint2, Putrajaya, Malaysia

Changing ecosystem and natural habitats with manmade infrastructures and surface materials lead to higher temperature in cities and urban areas than surroundings. As cities are mostly paved by materials, surface temperature mitigation should be considered as a crucial strategy for urban planners and...

Based on comparative study, it was revealed that pavement materials with higher albedo and lower emissivity like Blue Impala were 15.5 ºC cooler than asphalt in open space during 12:00-15:00. Additionally, under shade location was the coolest landscape environment for all pavement materials. This study concurs with previous works in which trees and shades help to reduce surface temperature in tropical climate. However, near water location gave mixed results as Blue Impala and Rosa Tanggo recorded increase in temperature in contrast to Fontana Concrete and asphalt that showed reduction in temperature. Ultimately, this study provides a systematic reference for future designing and planning on pavement for surface temperature reduction in urban areas to mitigate urban heat island effect.
