ASHRAE Standard 62.1 Addendum ab Establishes CO2 Maximums in Occupied Spaces

ASHRAE Standard 62.1 has long been the “go to” for specifying minimum ventilation rates and establishing guidelines for indoor air quality in Commercial HVAC applications.

As demand control ventilation applications (DCV) become ubiquitous in the Commercial HVAC market, so has real-time CO2 monitoring. Real-time CO2 monitoring is a known way to determine, not only fresh air rates in a space, but also occupancy within a space. The main challenge with AHSRAE 62.1-2022 is that there was no standardization or guidelines for Engineers, Design Professionals or Building Owners to follow when determining how to deploy real-time CO2 monitoring for DCV.

Addendum ab to ASHRAE 62.1-2022 addresses this challenge through the addition of standard differential CO2 concentration limits above ambient (400ppm) specifically for use with CO2 DCV systems specific to the type of Occupancy Category.

Table 6.1 (Page 5) establishes this maximum CO2 threshold above ambient for specific Occupancy Categories. For example, a classroom with students aged 5-8 would have a maximum CO2 threshold of 1000ppm (400ppm ambient + 600ppm CO2 above ambient).

Addendum ab Compliant NDIR CO2 Sensors

Addendum ab also establishes accuracy requirements for CO2 sensors used in DCV applications.

Section 6.2.6.1.3.4 states that CO2 sensors shall be certified by the manufacturer to be accurate within +/-75ppm at concentrations of 600, 1000, and 2500ppm when measured at seal level at 77 degrees Fahrenheit (25 degrees Celsius).

Innovaer Technologies is the market leader in CO2 measurement applications. Our portfolio of single-channel and dual-channel NDIR sensors ensure our OEM Partners are complaint with Addendum ab.

Designing Battery Powered CO2 & Particulate Matter Air Quality Solutions?

Keep reading… we did the math for you!

Breathing clean air is essential to a long healthy life and should be viewed in a manner similar to drinking clean water. Given that we spend the majority of our time indoors, indoor air quality (IAQ) is coming into focus as something that needs to be measured, controlled and optimized. As such, our buildings are not “ready” for the widespread implementation of air quality sensors without significant investment in upgrading the building infrastructure.

Innovators in the building automation space are accelerating the development of solutions that can measure IAQ in near real-time, analyze the IAQ trends and optimize the air we breathe. To remove one of the major cost barriers in implementing these solutions, there has been an increased focus on battery powered devices as these devices reduce the capital required to bring IAQ measurements into the building.

PM2105L Low Power Particulate Matter Sensor

The PM2105L is a laser scattering particulate matter measurement technology that can provide mass concentration output measurements as well as a particle count measurement.

Additional Features:

  • Sensor can be repeatedly be powered on / off
  • Stable performance within 4 seconds after power on
  • PM1.0, PM2.5, PM10 particulate matter mass concentration output
  • 0.3µm, 0.5 µm, 1.0 µm, 2.5 µm, 5.0 µm, 10.0 µm particle count output
  • Calibrated to the GRIMM standard (TSI available)
  • UART and I2C communication interface
  • 14+ years lifetime

Example designs from Cubic Sensors & Instruments have calculated the battery life for some common applications using AA batteries as the power source. These calculations have shown that the AA battery life can be optimized to achieve close to 3 years of battery life!

The battery life is dependent on the number of AA battery cells and the measurement interval of the PM2105L. Here are some examples of how the number of battery cells and measurement period impact the battery life:

4 AA Batteries

  • 4 sequential readings every 10 minutes – 1.10 years battery life
  • 4 sequential readings every 20 minutes – 2.03 years battery life
  • 4 sequential readings every 30 minutes – 2.91 years battery life

3 AA Batteries

  • 4 sequential readings every 10 minutes – 0.80 years battery life
  • 4 sequential readings every 20 minutes – 1.53 years battery life
  • 4 sequential readings every 30 minutes – 2.18 years battery life

2 AA Batteries

  • 4 sequential readings every 10 minutes – 0.55 years battery life
  • 4 sequential readings every 20 minutes – 2.03 years battery life
  • 4 sequential readings every 30 minutes – 1.45 years battery life

CM1106SL-NS Low Power CO2 Sensor

The CM1106SL-NS is the next generation of NDIR carbon dioxide (CO2) measurement sensors specifically designed for battery powered applications without sacrificing measurement accuracy.

The integrated ABC algorithm ensures that the sensor is providing reliable carbon dioxide (CO2) measurement for over 15 years.

Additional Features:

  • Range: 0-5000ppm
  • +/-40ppm +3% with dynamic averaging
  • 37uA current consumption with 2-minute measurement cycle
  • 74uA current consumption with 1-minute measurement cycle

Example designs from Cubic Sensors & Instruments have calculated the battery life for some common applications using AA batteries as the power source. These calculations have shown that the AA battery life can be optimized to achieve close to 7+ years of battery life!

The battery life is dependent on the number of AA battery cells and the measurement interval of the CM1106SL-NS. Here are some examples of how the number of battery cells and measurement period impact the battery life:

3 AA Batteries

  • 6 sequential readings every 2 minutes – 1.91 years battery life
  • 6 sequential readings every 5 minutes – 4.25 years battery life
  • 6 sequential readings every 10 minutes – 7.18 years battery life

2 AA Batteries

  • 6 sequential readings every 2 minutes – 1.27 years battery life
  • 6 sequential readings every 5 minutes – 2.83 years battery life
  • 6 sequential readings every 10 minutes – 4.79 years battery life

1 AA Battery

  • 6 sequential readings every 2 minutes – 0.64 years battery life
