06. Microbe and mold control
To reduce mold and bacteria growth within buildings, particularly from water damage or condensation on cooling coils.
Mold often grows on cooling coils in HVAC systems due to moisture condensation and can be introduced into the building’s indoor air. It can also occur on or within wall assemblies due to water damage or improper detailing in humid locations, for example kitchens and bathrooms. Mold spores can trigger asthma, headaches, allergies and other respiratory system disorders.
In buildings that rely on a mechanical system for cooling, one of the following requirements is met:
