The research group Bioinformatics and Biomedical Signals Laboratory (B2SLab) of the Biomedical Engineering Research Centre (CREB) and the company AMPER S&C IoT are participating in the VIDA project, which aims to develop a system for smart ventilation and detection of the level of purification of indoor air.



The smart ventilation system will enable new indoor air quality metrics to be defined, to identify the right time and way to ventilate. Ideally, ventilation should be natural, so that fresh air enters from the outside and mixes with indoor air. However, the exterior air quality may not be optimal or the air could be very cold and cause a drop in indoor temperature. For this reason, other forms of ventilation should be activated, such as the use of extractors or purifiers.

Beyond the CO2 measurements that are made routinely, some metrics will be defined in the project that will include relevant information on indoor and outdoor air quality, such as the number of particles in suspension and the concentration of volatile compounds. There are many applications for the system, particularly in rooms with a high density of people where special attention to air quality is required, including schools or care centres. In addition, the ventilation system that is developed will help to fight against the COVID-19 pandemic, as it will determine whether the ventilation is adequate to ensure safety in indoor environments.

This project has received an Innotec-2020 grant from the Government of Catalonia’s ACCIÓ. The project will end in 2023.
