Why is it necessary to monitor CO2 concentration in buildings

Controlling and monitoring indoor levels of carbon dioxide is essential for everyone’s health, safety, and the energy efficiency of buildings. Similar to how we need to breathe fresh air, so do buildings. Ventilation in a building is the essential process of replacing stale air with fresh air. Without engineered ventilation, buildings become susceptible to stagnant air, mold, bacteria, and potentially harmful gasses like radon, VOCs (volatile organic compounds), and carbon dioxide. Prolonged exposure to these elements can lead to “sick building syndrome” where occupants experience acute health and comfort effects.
