Allowing warm, humid air to enter an unconditioned environment that contains cold surfaces only exacerbates the problem. The information gleaned from those studies has shifted the thinking to sealing the crawl space and installing mechanical ventilation. What I find most interesting is the results those studies revealed about energy consumption, and about how that information is being used today.
