Sub-PPM level indoor air quality monitoring: The clean-air project

The occurrence of the Sick Building Syndrome (SBS) inside buildings equipped with Heating Ventilation Air Conditioning (HVAC) Systems can be reduced by controlling the concentration of pollutants in the indoor air. This can be achieved by smart intervening procedures implemented in the HVAC control system, which will be operated on the basis of reliable information about both the indoor and outdoor air quality, aiming to ensure the most appropriate amount of ventilation. Within CLEAN-AIR, we are developing a dedicated, miniaturized, low-cost electronic nose realized using state-of-the-art microsystems/sensors fabrication technologies. This e-nose provides data as input to the specifically implemented smart intervening procedures, which will allow the HVAC system to be operated under demand, rather than by a fixed duty cycle.
