The project aims to develop the technical culture for Improving Air Quality (IAQ) in schools. It involves the development of technological solutions with low architectural impact and a methodological approach to classify, design, implement, measure and manage IAQ conditions. The general objective is to solve the problem of poor air quality in school buildings. The partners will develop solutions and methodologies in cooperation with companies in the cross-border area: mechanical ventilation installers, door and window fitters, management systems (ICT), manufacturers and distributors of indoor materials, design studies focused on IAQ. The project includes measurement campaigns (before and after demonstration rehabilitation interventions), as well as the development of guidelines for the design and management of IAQ in schools, supporting designers, construction companies, works managers and users.
