Microbe and mold control
To reduce mold and bacteria growth within buildings, particularly from water damage or condensation on cooling coils.
Part 1 applies to all cooling coils and drain pans located within the primary air handling unit and any secondary equipment downstream. Note, a combination of UV lights and/or quarterly inspections is acceptable to comply with the part.
Project teams should calculate the power (irradiance) received by the cooling coils from the ultraviolet lamps to ensure the effectiveness of the system.
Yes, in order to demonstrate compliance with the preventative maintenance plan requirement, photos must be taken during the quarterly inspection. These photos will then need to be submitted to the IWBI once a year as part of the ongoing documentation requirements.
Feature 6 requirements do not distinguish between types of HVAC systems, and would need to be met in all mechanically cooled systems.
No, a mold inspection will be conducted by the WELL Assessor during the projects Performance Verification.
UV lamps should be employed on all cooling coils and drainage pans within the fan coil units in all mechanical units.
Yes, projects which meet the cleaning and reporting requirements outlined in option b of part 1 are not required to use UV lamps.
