Maximize Your IWBI WELL V2 Scorecard With Indoor Air Quality Optimizations From Kaiterra

There are many facets to healthy indoor environments, from acoustics and lighting to ergonomics and thermal comfort. One of the most important of these facets is indoor air quality. With a deep connection to health and well-being, promoting good indoor air quality is essential for building occupant health and is crucial for earning a WELL certification. 

What Is WELL?

The WELL Standard was established by the International WELL Building Institute (IWBI) to advance health and wellness through the transformation of the built environment.

Building off WELL v1, IWBI launched the WELL v2 pilot program, which focuses almost exclusively on building occupant health and well-being. Because the enormous impact of air quality on our bodies, air is one of the central concepts WELL aims to enhance. In the context of WELL as a certification program, improving air quality and air quality awareness can earn many points toward certification. 

Achieving IWBI WELL V2 With IAQ Optimizations

Indoor air quality optimizations can earn your project points through A08 and T06. We’ve broken down these categories below.

A08 Air Quality Monitoring and Awareness (2 points)

WELL divides air quality monitoring and awareness optimization into two distinct parts. Part I focuses on implementing air quality monitors, and Part II focuses on promoting air quality awareness. 

Part I: Implementing air quality monitors is worth one point and sets air quality parameter, density, data, and calibration requirements for air quality monitors used for WELL. To satisfy these criteria, monitors must measure three of the following:

  • PM2.5 or PM10 (accuracy 5 μg/m³ + 15% of reading at values between 0 and 50 μg/m³)
  • Carbon dioxide (accuracy 50 ppm + 3% of reading at values between 400 and 2000 ppm)
  • Carbon monoxide (accuracy 1 ppm at values between 0 and 10 ppm)
  • Ozone (accuracy 10 ppb at values between 0 and 100 ppb)
  • Nitrogen dioxide (accuracy 20 ppb at values between 0 and 100 ppb)
  • Total VOCs (accuracy 20 μg/m³ + 20% of reading at values between 150 and 2000 μg/m³)
  • Formaldehyde (accuracy 20 ppb at values between 0 and 100 ppb)

The placement, density, and data collection frequency of the monitors also must fit the following criteria:

  • Monitor density is minimum one per floor or one every 325 m² [3,500 ft²], whichever is more stringent.
  • Measurements are taken at intervals of no longer than 10 minutes for particulate matter and carbon dioxide and no longer than one hour for other pollutants.
  • Data are analyzed for regularly occupied hours (e.g., median, mean, 75th, 95th percentile) and submitted annually through WELL Online.
  • Monitors are recalibrated or replaced annually, with documentation attesting to their calibration or replacement submitted annually through WELL Online.

Part II: Promote Air Quality Awareness takes Part I a step further. To encourage the dispersion of air quality data to regular building occupants, WELL offers an additional point for projects to display their air quality data either through display screens or through digital means, including a phone application or website. Projects must also promote air quality education by offering at least two of the following:

  • A digital or physical library with at least two indoor air quality resources
  • A labeling system for the air quality monitors in Part I
  • Paper or digital communication about IAQ health impacts every quarter
  • Educational training provided by an IAQ expert annually

T06 Thermal Air Comfort Monitoring (1 point)

To attain points for T06, projects must monitor thermal parameters in real-time and display environmental measures according to specific guidelines. The following monitor requirements must be satisfied for your building project gain points for thermal comfort monitoring:

  • Measurements are taken in occupied zones at least 1 m [3.3 ft] away from exterior walls, doors, direct sunlight, air supply/exhausts, mechanical fans, heaters or any other significant source of heat or cold.
  • The sensor placement density is minimum one per floor or one every 325 m² [3,500 ft²], whichever is more stringent.  
  • Measurements are taken at intervals and heights specified in the table below:


Sampling Interval

Sampling Height Above the Floor  

Dry-bulb temperature  

10 minutes or less

1.1–1.7 m [3.6–5.6 ft]      

Relative humidity

10 minutes or less

1.1–1.7 m [3.6–5.6 ft]    

Air speed (only if elevated air speed is used)

3 months or less

1.1–1.7 m [3.6–5.6 ft]      

Mean radiant temperature

3 months or less

1.1–1.7 m [3.6–5.6 ft]

  • Data are analyzed for regularly occupied hours (e.g., median, mean, 75th and 95th percentile) and annually submitted through WELL Online.
  • Dry-bulb temperature and relative humidity sensors are recalibrated or replaced annually and certificates attesting their calibration or replacement are annually submitted through WELL Online. Air speed and mean radiant temperature sensors used for quarterly measurements are calibrated as per manufacturer's specification.

Like Part II from A08, projects need to go beyond parameter monitoring and provide thermal comfort values to regular building occupants. Again, these readings can be provided by a display or thorough digital options, including a phone application or website. 

Earning Points Toward WELL With Air Quality Monitoring From Kaiterra

From installation to air quality education, Kaiterra’s line of commercial devices is designed to help you achieve WELL v2 optimizations A08 and T06, adding three points to your WELL application. 

Continuous monitoring

Kaiterra’s commercial air quality monitors sample for PM2.5, TVOC, CO2, dry-bulb temperature, and relative humidity every minute, exceeding the required sample interval of ten minutes or less. Accuracy and resolution also satisfy WELL’s requirements.

Annual and certified sensor calibration 

Kaiterra’s commercial air quality monitors use a modular design to meet WELL’s annual calibration requirements. Instead of having to remove and ship the monitor to a calibration facility, Kaiterra's modular sensors can be swapped out with new sensors for convenient, efficient calibration.

These new sensors also come with a certificate of calibration that can be submitted on WELL Online, ensuring that all calibration requirements are met on a cost-effective basis. 

Flexible data export

Whether online or offline, Kaiterra commercial devices easily export data over email, USB, or micro-SD memory card. This data collection allows you to access your project and submit your performance verification on WELL Online.

Simple installation

The Sensedge and Sensedge Mini can be easily installed in under 10 minutes, and the Sensedge can be prominently displayed in regularly occupied spaces to suit the optimization’s placement requirements.

Connected dashboard & online resources

A08 and T06 both feature measurement display components, requiring air quality and thermal comfort values to be available to regular building occupants. To achieve this component of A08 and T06, you can use the Kaiterra dashboard, a powerful tool for viewing and comparing real-time air quality readings accessible through your browser and phone and directly through our API key.  

Additionally, Kaiterra’s free digital library is packed full of air quality tips and information, which can be used to raise occupant awareness in Part II of A08. 

Proven Success: Kaiterra Commercial Air Quality Monitoring in IWBI’s NYC Office

In 2019, IWBI’s global headquarters relocated its office and earned a WELL Platinum rating. 

IWBI NYC Office - 2

IWBI utilized the Kaiterra Sensedge in its NYC headquarters. Note: air quality readings in the above image do not reflect the actual air quality of the space.

Featuring Kaiterra’s Sensedge, among other indoor health optimizations, IWBI received over 80 points toward its own certification program. To read more about this project, check out our full case study: How IWBI Transformed Its Aging NYC Office Into a Healthy Workplace.
