How Can Cities Cool down Large Urban Car Parks?
The urban heat island effect occurs when pavements, roads, and buildings absorb the sun's heat and radiate it back, causing the temperature to increase and preventing the city from cooling down. With the growing reliance on cars in cities, the number of urban car park spaces is also increasing to accommodate buildings. This has resulted in the conversion of large areas of pervious land covered with vegetation into impervious hard surfaces for more car parks. The use of materials like asphalt, combined with the lack of shade, reflective steel surfaces of parked cars, and loss of greenery in these extensive car parks, contributes to the amplification of high-temperature effects and extreme heat events, making urban spaces uncomfortable. This transformation is impacting the climate of car-dependent regions and calls for collaborative ideas and efforts to mitigate the negative effects of rising heat.
