How Kaiterra’s Sensedge Meets WELL Certification Requirements

Because of the popularity of the WELL certification program, we’ve naturally received inquiries about how the Sensedge can be used as an air quality monitor for WELL.

The Sensedge is fully compliant with the WELL certification program. To illustrate, we’ve provided a side-by-side comparison of WELL’s air quality monitoring and thermal comfort requirements, and the Sensedge’s continuous monitoring capabilities below:

WELL	Requirements		Sensedge	Compare
A01 Part 1; A01 Part 5; A05 Part 1; A07 Part 2; A08* Part 1	PM2.5 accuracy	± 5 µg/m3 + 20 % at 1-100 µg/m3	± 10% (<30 μg/m³: ± 3 μg/m³) between 30 and 1000 μg/m³
A01 Part 2; A01 Part 5; A08* Part 1	TVOC accuracy	± 20 µg/m3 + 15% at 1-500 µg/m3	±15 % ±8 ppb between 0 - 60000 ppb
A03 Part 1; A06 Part 1; A08* Part 1	CO₂ accuracy	± 50 ppm + 5 % at 500-2000 ppm	± 3% ± 50 ppm between 400 and 2000 ppm
A07 Part 2; T01 Part 1; T01 Part 2; T06 Part 1	Temperature (dry-bulb) accuracy	± 0.5 °C [± 0.9 °F]	RESET accredited Grade B monitor
A07 Part 2; T01 Part 1; T01 Part 2; T06 Part 1; T07 Part 1	Relative humidity accuracy	± 5 % at 10-90 %	± 5 % between 0-99 %
A08	Sensor calibration	Monitors are recalibrated or replaced every 3 years	No calibration needed - simply replace the modules
A08	Measurement intervals	Measurements are taken at intervals of no longer than 10 minutes for PM and CO2 and no longer than one hour for other pollutants	One minute
A08	Environmental measures display	Real-time display of air pollutants	7’’ Full Color Touchscreen Display

*For WELL, you only have to measure three of the above air pollutants at once to meet the A08 air quality monitoring requirement.

** Continuous monitors that are RESET accredited Grade B or above can be utilized for features and parts that can be met with continuous monitors.

Kaiterra's Sensedge monitors three air pollutants at once (PM, CO₂, and TVOC), and it also measures temperature and humidity so you can maximize the comfort of your project. The Sensedge's one-of-a-kind modular sensor design can also allow for potential additional sensing parameters for continuous monitoring such as ozone, nitrogen dioxide, carbon monoxide, and more.

Because of this modular design, the Sensedge itself does not need to be calibrated. Rather, you only need to remove the sensors and replace them with new ones. The previously weeks-long process of calibration only takes seconds with the Sensedge, and the Sensedge can readily be used as an air quality monitor for a WELL certification.
