Indoor air quality (IAQ) technologies combining ultraviolet germicidal irradiation (UVGI) and gas-phase purification allow engineers and facility managers to reduce energy consumption while ensuring a safe environment for building occupants.

All three of these must be present for an assembly to achieve its anticipated lifespan. As a construction activity, roofing requires the same high level of diligence as other construction trades, such as mechanical and electrical systems.
