My crawlspace had no provide, return or exhaust air & no dehumidifier. Near-dewpoint equilibrium was apparently as a result of moisture diffusion though the hardwood flooring and perhaps a little provide air duct leakage.

Proponents of UFAD point to the decrease fan pressures required to deliver air in a constructing via the plenum as in comparison with via ducts. Typical plenum pressures are 25 pascals (0.0036psi) (zero.1 inch of water column) or less.
