The power evaluation of UFAD methods is a not fully solved problem, which has led to quite a few research tasks throughout the building science and mechanical engineering group. Proponents of UFAD level to the decrease fan pressures required to deliver air in a building by way of the plenum as in comparison with by way of ducts. Typical plenum pressures are 25 pascals (zero.0036psi) (zero.1 inch of water column) or much less.
