According to Feature A09: Pollution Infiltration Management, part 3 of the WELL Core requirements, the project team must install self-closing doors between high-humidity spaces (such as kitchens, bathrooms, and laundry rooms) and regularly occupied spaces1. This helps prevent the spread of moisture and odors that can affect indoor air quality and comfort2.
