Cool city as a sustainable example of heat island management case study of the coolest city in the world

Abstract EN

Urbanization negatively impacts the urban environment mainly by the production of waste heat from refrigeration systems, although industrial processes and motorized vehicular traffic have also been recognized as additional causes of the urban heat island (UHI) effect.

The UHI negatively impacts the residents, with spillover effects for environmental aspects.

In urbanized areas, it is a critical factor for air quality management and public health.

The UHI and strategies to implement its mitigation are becoming increasingly important for governmental agencies and researchers.

The problem is how to deal with UHI effects? Accordingly, the main aim of this paper is to determine the UHI mitigation strategies and their effectiveness in terms of cooling and temperature reduction in cities at the level of urban design.

This goal is achieved through exploring the concept of the cool city, as it is the key factor, from the theoretical, analytical, and practical viewpoints, to diminishing the urban heat release.

Then, the paper analyzes how the concept of the coolest city in the world (Stuttgart, Germany) is developed and explores a practical approach toward cool cities.

Finally, it suggests a set of recommendations to develop the urban environment in Greater Cairo by applying the cool city concept.
