Cooling Benefits of Urban Cooling Infrastructures: A Review

Abstract

As climate change intensifies, a significant rise in urban temperatures is exacerbating the global menace of urban heat, increasingly impacting the human residential environment. This paper conducts a comprehensive analysis of existing literature and data to explore the multifaceted impacts of urban heat on global cities across social, environmental, health, and economic domains. The article elaborates on the definition, cooling mechanisms, and primary types of Urban Cooling Infrastructures (UCI), including blue infrastructure, green infrastructure, white and grey infrastructure, and urban design. It emphasizes the importance of UCI in improving the quality of the urban residential environment against the backdrop of global warming. By showcasing the comprehensive cooling benefits, the study contributes not only to enhancing overall urban resilience but also offers profound insights for sustainable urban development. The research aims extend beyond assisting policymakers and urban planners in formulating effective strategies for climate resilience and sustainability. It also seeks to guide future research directions in UCI within the context of widespread urban heatwaves.
