Experimental study on the thermal characteristics of urban mockups with different paved streets

Pavements in urban area absorb more sunlight due to the canyon-like geomorphology of geometry and store heat great thermal bulk properties concrete. Heat released from pavements warms up air, contributing island. Recently, uses cool reduce pavement temperature as an island mitigation have gained momentum. Understanding solar insolation a is important adopt right option for place. This study measured paved streets mockup 4 days summer. It found that east-west (EW) are hottest place area, followed by intersection, finally south-north (SN) street increasing pavement’s albedo reduces effectively. The dark gray open space hotter than canyon. storage building blocks keeps warmer 2 °C at nighttime. EW exposed long hours, so it suitable preferentially developing reflective pavements.
