Overventilating in hot, humid climates

Ashrae 62.1 and 62.2 standards set minimum ventilation rates that provide acceptable indoor air quality (IAQ) in occupied places. But these rates contribute to building mold problems in hot, humid climates. The aim of this paper is to see if those minimum ventilation rates should be lowered in those regions, or if other options could mitigate the problem, including energy recovery ventilators, stand-alone dehumidifiers, and low sensible-heat-ratio air-conditioning equipement being developed by the industry.
