Aircuity Myth Busters

MYTH: Installing discrete CO2 sensors and calibrating them every 6 months will provide the same accuracy as Aircuity.

Founder Gordon Sharp says: BUSTED!

Calibrating sensors every six months will help with sensor accuracy but will not solve offset drift. Aircuity’s differential measurement approach uses one sensor to measure the reference and the room air to eliminate offset drift, which is the largest component of drift. Even with 6-month calibration, the offset drift can be very large after only a few weeks. Field calibration addresses the gain and linearity drift, which occur at a slower rate.

Furthermore, to address and deliver optimal sensor accuracy, Aircuity directly compensates for barometric pressure and is not susceptible to impact of humidity. Commercial CO2 sensors do not, and both of these effects can vary the output of the sensor by as much as 100 PPM. Finally, Aircuity filters the air going to the sensors to again limit the gain and linearity drifts.

So, calibrating discrete CO2 sensors every 6 months will not solve these accuracy and drift issues and, thus greatly have far less accuracy compared to Aircuity. For acceptable performance at minimum, there must be differential measurement, barometric compensation, no humidity influence, and filtering of the sensed air with a HEPA grade filter.

In Case You Missed It: Air Quality as a Service in Forbes

For building owners and facilities managers, indoor air quality (IAQ) is taking center stage as they plan for safe reopening of workplaces in 2021. IAQ solutions can help reduce the likelihood of airborne disease transmission.

"Aircuity monitors many IAQ parameters and designs custom solutions, which are funded through savings from an organization's operational and energy savings. The new air quality as a service (AQaaS) model requires no or low upfront capital and can deliver rapid ROI, creating a win-win result for all stakeholders. Building owners see improved IAQ and operations savings, occupants have improved peace of mind and lower rates of illness, and facilities managers have a platform to manage and maintain air quality across the facility lifetime."
