Reduce mold and bacteria growth through condensation management and reduce levels of microbes within occupied spaces.
Implement Ultraviolet Air Treatment (1 point)
Project utilizes one of the below:
- Projects with a forced-air cooling system use ultraviolet lamps to irradiate the surfaces of the cooling coils and drain pans of the mechanical system supplies.
- Projects without a forced-air cooling system use standalone ultraviolet germicidal irradiation air sanitizers in all spaces with more than 10 regular occupants.
Evidence that the device has been replaced or maintained according to manufacturer's recommendation is submitted annually through WELL Online.
Manage Condensation and Mold (1 point)
Condensation management is addressed within the project and considers the following:
High interior relative humidity levels, particularly in susceptible areas like laundry rooms, below-grade spaces and other high-humidity areas.
Air leakage that could wet either exposed interior materials or interstitially hidden materials.
Cold surfaces such as basements, slab-on-grade floors or the inside of exterior walls.
Oversized air conditioning units.
The following requirements are met:
Annual inspections for signs of water damage or pooling, discoloration and mold on ceilings, walls and floors is performed by a professional demonstrated not to have a conflict of interest. The report is submitted annually through WELL Online.
One of the below is met:
- Project achieves cooling coil mold reduction as per Part 1: Implement Ultraviolet Air Treatment.
- All cooling coils (where applicable) are inspected on a quarterly basis for mold growth and cleaned if necessary. Dated photos demonstrating adherence are submitted annually through WELL Online.
For projects with tenants, there is a system in place for notifying building management about mold or water damage and addressing concerns.
