06. Microbe and mold control
Mold often grows on cooling coils in HVAC systems due to condensation and can be introduced into the building's indoor air. It is also prevalent on or within wall assemblies if water damage occurs or if there is improper detailing in humid locations such as kitchens and bathrooms. Mold spores can cause allergic reactions and respiratory problems that in some cases can be severe.
This feature requires the use of ultraviolet germicidal irradiation (UVGI) devices to manage mold and bacteria on cooling coils as well as inspections for signs of mold outside of the air handling system.
The following requirements are met:
Urea-formaldehyde presence is limited in the following components to 100 ppm:
