Air quality monitoring and feedback

Building performance 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. WELL requires the continuous gathering and transmission of data to a central repository that is used to update the standard on regular intervals.

This feature requires real-time measurement, recording and transmission of key indoor air quality metrics as well as ambient outdoor air quality. This data is reported to the building occupants and to the IWBI.

Part 1: Indoor Air Monitoring

Monitors measure 2 of the following pollutants in a regularly occupied space within the building, at intervals no longer than once an hour, and results are annually transmitted to the IWBI:

a) Particle count (resolution 35,000 counts per m² [1000 counts per ft²] or finer) or particle mass (resolution 10 μg/m³ or finer).

b) Carbon dioxide (resolution 25 ppm or finer).

c) Ozone (resolution 10 ppb or finer).

Part 2: Air Data Record Keeping and Response

To consistently meet the WELL parameters, projects provide a written policy specifying:

a) Detailed enforcement strategies for monitoring and record-keeping of parameters listed in the Air Quality Standards Feature.

b) Records be kept for a minimum of 3 years, including full data from field inspectors or laboratory results where appropriate.

c) Detailed plan for action and remediation of unacceptable conditions.

Part 3: Environmental Measures Display

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]:

a) Temperature.

b) Humidity.

c) Carbon dioxide concentration.

d) Sound levels.
