The use of raised access flooring provides great flexibility in reconfiguring office spaces due to changes in staffing or the introduction of new technology and equipment. This flexibility is enhanced when underfloor utility distribution is included. Underfloor Air Distribution (UFAD) not only increases configuration flexibility but also provides improved air quality and comfort for the inhabitants of the space.
In a traditional overhead air distribution system, the air is being fed from, and returned to, ductwork located in the ceiling. The flow of air down into the space is met by the natural tendency of warmer air to rise up towards the ceiling. This creates a turbulent zone where fresh air and stale air are mixed, resulting in lower quality air at the occupants level. In periods where cooling is necessary, the supply air temperature needs to be lowered significantly below the desired temperature in order to compensate for this mixing and heating.
