Dioxide Materials is Developing Inexpensive Low Power CO2 Sensors for Demand Control Ventilation

Demand control ventilation is a method to reduce the energy needed to operate heating, ventilation and air conditioning (HVAC) systems. Presently buildings are ventilated with outside air to keep the inside air fresh and odor free. The ventilation runs all of the time even when the ventilation is not needed. This wastes energy because the outside air needs to be heated or cooled. Demand control ventillation uses CO2 sensors to measure the indoor air quality and determine how much ventilation is needed. A fan controller is then used to adjust the ventilation rate accordingly. Less electricity and natural gas are needed for the HVAC system, which lowers energy bills and reduces the carbon footprint of the building.
