Passive cooling strategies require strict adherence to the physical world. Ones imagination creates the flow of ideas that can blossom into a comfortable setting, but the reality of design, construction and cooperation has to be observed and accepted. Physical laws govern as natural processes follow the path of least resistance. In order for us to overcome these laws extra energy is required. That is why passive cooling designers must investigate how to create a comfortable setting by understanding how natural procedures work. The evaporative cooling phenomena and the humidification phenomena are similar processes, but they can have opposing results with respect to the comfort level. A review of each process reveals that air movement plays an important role in determining which phenomena will be present.
