The temperature rise just isn't considerably affected by the perimeter zone orientation, the interior heat gain and the window-to-wall ratio. Supply plenum air temperature rise, thus, has implications on the vitality saving potential of UFAD techniques and their ability to fulfill cooling necessities with supply temperatures above those of standard overhead systems. Current analysis means that each vitality and thermal performance may be improved in UFAD techniques by ducting air to perimeter zones where hundreds are usually the best.
