18. Air quality monitoring and feedback
To monitor and effectively remediate indoor air quality issues and inform building managers and occupants of the quality of the indoor environment.
Building performance, such as ventilation and infiltration rates, is highly variable and has a direct effect on indoor air quality. To maintain ideal performance metrics, projects must continuously gather data on building performance. Collecting this data allows individuals to be aware of and promptly fix any deviations in indoor quality metrics.
Monitors measure 2 of the following pollutants in a regularly occupied or common space (minimum one per floor) within the building, at intervals no longer than once an hour (measured at 1.2-1.8 m [4-6 ft] above the floor), and results are annually transmitted to the IWBI:
In an effort to consistently meet the WELL parameters, projects provide a written policy specifying:
Real-time display of the following indoor environmental parameters are made available per 930 m² [10,000 ft²] of regularly occupied space on a screen no smaller than 15 cm [5.9 inches] by 13 cm [5.1 inches]:
