Building Carbon Dioxide and Airborne COVID-19 Spread

Building Carbon Dioxide and Airborne COVID-19 Spread. Increased occupancy leads to higher building carbon dioxide levels. With proper ventilation, this isn’t a problem. However, poor ventilation impacts indoor air quality which is made even more unsafe by viruses. It is established science that the SARS-CoV-2 virus spreads by aerosol ...

Demand-Controlled Ventilation (DCV) - SVACH

Designers assume that controlling CO2 controls all occupancy-related pollutants. CO2 sensors are relatively precise, reliable, and inexpensive compared to other types of DCV pollutant sensors. Occupancy sensors count occupants and regulate ventilation airflow accordingly. A major purpose of ventilation systems is to control relative humidity.
