Air quality monitoring and feedback

Building performance and indoor air quality can be highly variable. To maintain ideal performance metrics, projects must continuously gather data on building performance. Monitoring these metrics allows buildings to make adjustments when conditions diverge from ideal thresholds.

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: Ventilation Design

One of the following requirements is met for all spaces:

a.⁶ Ventilation rates comply with all requirements set in ASHRAE 62.1-2013 (Ventilation Rate Procedure or IAQ Procedure).

b.⁶ Projects comply with all requirements set in any procedure in ASHRAE 62.1-2013 (including the Natural Ventilation Procedure) and demonstrate that ambient air quality is compliant with either the U.S. EPA'S NAAQS or passes the Air Quality Standards in the WELL Building Standard for at least 95% of all hours in the previous year.

Part 2: Air Data Record Keeping and Response

In an effort 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 are to 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 m_ [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.
