To reduce occupant exposure to combustion-related air pollution from heating and transportation sources.
Part 1: Carbon filtration
To reduce VOCs in the indoor air, buildings which recirculate air use one of the following methods:
- Activated carbon filters or combination particulate/carbon filters in the main air ducts to filter recirculated air.
- A standalone air purifier with a carbon filter used in all regularly occupied spaces.
Part 2: Air Sanitization
Spaces with more than 10 regular occupants, within buildings that recirculate air, use one of the following treatments or technologies to treat the recirculated air, either integrated within the central ventilation system or as a standalone device:
- Ultraviolet germicidal irradiation.
- Photocatalytic oxidation.
Part 3: Air Quality Maintenance
As evidence that the selected filtration/sanitation system chosen continues to be fully operational, projects must annually provide IWBI with:
- Records of air filtration/sanitization maintenance
Coating including CleanAir technology
Improving air quality is a priority for those with particular sensitivities. Targeting formaldehyde is strategic as this chemical is recognized as a harmful Volatile Organic Compound (VOC) for the following reasons:
• At low exposure, it can cause headaches, irritation, asthma, nausea and discomfort; and
• At high exposure, formaldehyde is carcinogenic (class 1 according to the International Research Center on Cancer).
When CleanAir technology is included in the wall covering, up to 70% of the formaldehyde in the indoor air is immediately captured and neutralized. This performance is maintained even after several layers of paint are applied (if the product is a paintable one) and its efficiency has been proven for more than 10 years.
