For Feature A08: Air Quality Monitoring and Awareness, the WELL Building Standard specifies the minimum density of air quality monitors to ensure adequate coverage and accurate representation of indoor air quality across different spaces. The requirement of one sensor per 3,500 ft² (approximately 325 m²) is designed to provide a balance between comprehensive monitoring and practical implementation. This density allows for sufficient spatial resolution to detect variations in air quality in various areas of a building, facilitating targeted interventions and informing occupants about the air quality in their environment. It reflects WELL's focus on creating environments that support occupants' health and wellbeing by ensuring that air quality, a critical component of indoor environmental quality, is continuously monitored and managed.
