Consider Evaporative Rooftop Cooling

For some areas of the country, evaporative rooftop cooling is reducing summer cooling loads by as much as 25 percent. Prior to installation of such a system, a 124,000-square-foot software development facility in Dallas calculated that it needed to add 41 tons of additional air conditioning to adequately cool the building. What building owners discovered was the water-spray rooftop cooling cut the cooling load, allowing the company to recover the costs of its installation in one year.
