The control of air quality, the overall comfort of the inhabitants (acoustics, thermals, lights, etc.), the minimisation and/or treatment of emissions of gaseous or particulate pollutants, or conveyed by air, and the energy aspect of air conditioning processes and processes, are today a real challenge regarding the definition of rational management of this essential resource. The research axis“Interior Environmental Quality”QEI of the “SUSTABLE BITMENTS” programme aims to provide concrete solutions to this problem. 4 actions are drawn up in order to respond to the current shortcomings in research and development.
