Urban Heat Island (UHI) effect can be a major concern due to its detrimental impacts on the society, the environment, and the economy. Several studies have presented different urban heat island mitigation strategies (UHIMSs) and their level of effectiveness. Some of the strategies discussed included greenery, cool material usage in construction, green roofs, and evaporative techniques; however, these approaches vary with respect to their levels of sustainability and resilience. A thorough review of the literature shows that there is a lack of a comprehensive system that considers the various parameters that play a significant role in qualifying the selected strategies as suitable candidates to mitigate the effects of the heat island. As such, this research aims at identifying, classifying, and organizing these parameters in a comprehensive framework with respect to two main criteria, which are sustainability and resilience. This paper presents the initial steps of developing this framework through the structuring of a comprehensive hierarchy for the heat island mitigation systems. Each level of the hierarchy provides further insights about the relative importance of the identified attributes/features of the mitigation strategies with respect to the sustainability and resilience aspects. Collectively, the hierarchy will provide the main skeleton for developing a comprehensive decision support system (DSS) for selecting the most suitable UHI mitigation strategy.
