Incorporating revolving doors at the entrance of a building can effectively meet the WELL Building Standard's requirements for healthy entryways. Revolving doors act as an air lock, reducing the influx of pollutants and particulate matter from the outside environment into the building's interior. This design feature minimizes the entry of outdoor contaminants and helps in maintaining cleaner indoor air quality. The presence of grilles that measure the width of the entrance and extend 10 ft. (3 m) in the primary direction of travel further supports this by trapping dirt and water at the entrance, but the key mechanism for reducing airborne pollutants is the use of revolving doors, aligning with WELL's emphasis on air quality and health.
