New Buildings are built tighter to save energy while older buildings are implementing new measures to reduce heating and cooling loss. Reduced fresh air also prevents dilution of contaminated air resulting in an increase of contaminants as they are now trapped inside and are continually recirculated throughout the space.

Commercial and office Indoor Air Quality applications vary. Common issues facing owners, property managers, lessees, employees and visitors include those having to do with troublesome odors and maintaining clean air. It is not uncommon to have many diverse industries under one commercial roof, as such, air migrates throughout the building bringing with it airborne contaminants. UV systems can effectively address these many different IAQ issues.
