The demand-actuated control of ventilation appliances in the private, public and commercial sector is an area of application with great growth potential.
Because the human exhale carbon dioxide by normal breathing, the indoor CO2 concentration rises to values above the natural CO2 concentration.
This is noticed at about 1000 ppm by tiredness, decreasing concentrativeness and headaches. The intelligent control of ventilation systems by the assignment of CO2 as a reference parameter would therefore contribute to the improvement of the atmospheric environment and would additionally save a large part of the costs that accrue out of false ventilation and the involved power loss.
