Abstract
Passive cooling techniques have been used mostly in countries with hot and arid climates such as Iran, Egypt, and India. However, the use of this important technology has not been seriously considered until a time of energy crisis, and consequently, environmental crisis scenarios, emerge. Scholars have renewed their interest in investigating passive cooling technology, particularly the aspects of new materials, thermal comfort, energy efficiency, new designs, climate, and environmental considerations. This review paper highlights the opportunities to use green materials, such as geopolymers, as evaporative cooling materials with different types of industrial and agricultural waste products as components. Novel ideas for passive cooling design using ancient and nature-inspired concepts are also presented to promote green technology for future applications.

The global demand for energy will increase by 33% between the years 2010 and 2035
Environmental protection is a top global concern that requires the reduction of energy consumption
The use of climatic designs will translate into reduced energy costs
Summary
The global demand for energy will increase by 33% between the years 2010 and 2035. Such demand will raise energy-related CO2 emissions by 20%, thereby increasing long-term global temperature by over 3.5 ̋ C [1]. Efforts have been performed to reduce energy consumption consciously in the construction industry given that this industry accounts for approximately 40% of total global energy consumption [2]. The use of HVAC systems requires calibration with regard to passive cooling strategies because of the high energy consumption of such systems. This approach involves the use of both passive and hybrid cooling techniques to reduce energy consumption and improve thermal comfort. Evaporative cooling is a passive technique [5] that is applicable to regions with multiple climatic situations, such as those with hot and dry climate, and to regions with moderate climate [6]
