A conditioning system that conditions exterior air for use in a spray booth. The exterior air is conditioned and subsequently used to carry away coating mist, dust, and contaminants from a spray area. The conditioning system heats, cools, humidifies, and dehumidifies the exterior air to a variable set point. The variable set point, while bounded by dry-bulb temperature and relative humidity constraints, is selected based upon cost and/or energy minimization. Additionally, the set point selection may be based upon future predicted weather conditions that are determined with a mathematical profile of previous weather conditions and weather trends in a localized domain, where the localized domain is a geographic area surrounding a manufacturing plant that includes a spray booth.
