Adding outdoor air in hot humid climates causes moisture problems right? Sometimes. It depends on the condition of the house before you start to add outdoor air. In order to provide controlled ventilation in new houses constructed in hot humid climates without creating latent load problems it is necessary to take the following measures:
· Install tight ductwork and air handlers
· Balance interior air flows
· Size equipment correctly
· Provide supplemental dehumidification
