Industrial Measurements

Building ventilation is fundamental to maintaining proper and healthy indoor air quality. Nowadays, we also look to building ventilation to decrease risks to our health. However, how can you verify that the designed rates of ventilation are being delivered properly and effectively? While there are many parameters used to evaluate the air quality in a building, there is no other real-time, continuous measurement as proven and reliable as carbon dioxide.

In this hour-long webinar presented by ASHRAE Journal, Vaisala's Business Development Engineer Justin Walsh will discuss carbon dioxide measurements for building ventilation and why CO2 is a trusted parameter for the evaluation of ventilation effectiveness. Justin will cover:

  • CO2 as a ventilation indicator
  • The value of indoor air quality
  • IAQ measurement technology
  • Making control decisions on reliable data
  • Understanding calibration and traceability
