Concern with environmental emissions has focused attention on traditional forms of energy use in buildings, with a view to reducing and making more rational use of energy consumption. One area of concern is the traditional, refrigeration based, commercial air conditioning system, which has high levels of electrical power consumption in fans and refrigeration compressors. There is also concern among building owners and design teams, supported by the PROBE series of post occupancy studies, conducted by the CIBSE, that many buildings, with traditional forms of air conditioning, under perform in terms of occupant satisfaction, ease of operation and control, maintenance costs and successful commissioning. These developments have led to a search for lower energy and more satisfactory alternatives. Research into evaporative cooling indicates that the technique can offer a satisfactory alternative to refrigeration based cooling in a number of appropriate applications.
