The more people in a building, the more CO2. By measuring the CO2 level, you can regulate the airflow according to need. This will save energy and create a healthy indoor environment.

Key benefits of good indoor air quality:

  • Increased productivity level
  • Better decision making performance
  • Long-term health benefits

Building Management Systems

The primary indoor source of CO2 in office buildings is the breathing of the building’s occupants. CO concentration in office buildings typically ranges from 400 to 2,500 ppm. With CO2 measuring, it is possible to control individual fans, dampers, valves etc., which create a better indoor environment and energy savings. A common application is controlling ventilation in rooms with varying numbers of people, such as offices, classrooms, and cinemas. 

Indoor air quality also improves due to a reduction in the number of viruses and bacteria. Ventilating a room also reduces the number of particles occurring indoors. 

World Health Organization

In the publication “School Environment: Policies Current Status”, the World Health Organization (WHO) states that good indoor air quality, where carbon dioxide is one of the focus areas, is the basis of lower rates of absenteeism among students and teachers, stronger academic performance, better teacher retention and job satisfaction, cost savings in many areas including building maintenance, and less sick leave.
