The temperature rise just isn't considerably affected by the perimeter zone orientation, the internal warmth achieve and the window-to-wall ratio. Supply plenum air temperature rise, thus, has implications on the power saving potential of UFAD techniques and their capability to satisfy cooling necessities with provide temperatures above those of typical overhead methods.

While overhead methods sometimes use ducts to distribute the air, UFAD techniques use the underfloor plenum shaped by set up of a raised floor. The plenum usually sits 0.three and 0.46 metres above the structural concrete slab, although lower heights are potential. The most common UFAD configuration consists of a central air dealing with unit delivering air through a pressurized plenum and into the space by way of flooring diffusers. Other approaches could incorporate fan powered terminal models at the retailers, underfloor ducts, desktop vents or connections to Personal Environmental Control Systems. Open subfloor signifies that the airspace beneath the ground is unenclosed between floor and flooring stage, or enclosed by partitions which have more than the required subfloor vents.
