The authors assessed the annual cooling energy savings resulting from nighttime evaporative cooling in a small (10,000 ft/sup 2/ (929m/sup 2/)) office building. They used an hour-by-hour computer simulation to compare the performance of structural mass cooling and evaporative cooling of a chilled water storage tank at night in 11 U.S. climate zones. They studied direct and combined direct/indirect evaporative cooling systems that were incorporated in a variable-air-volume heating, ventilating, and air-conditioning system. The results show that cooling energy savings relative to conventional vapor-compression cooling are obtained with evaporative system in all of the climate zones studied when thermal mass, preferably in the form of structural mass, is incorporated. The results also indicate that in two of the climate zones studied, conventional cooling can be eliminated entirely by including thermal mass in the evaporative cooling system.
