Risk mitigation and promotion of a healthy indoor environment

Healthy living spaces can positively contribute to the well-being of occupants. Appropriate strategies for the removal, containment and dilution of contaminants can significantly mitigate the risks associated with them in indoor environments. These contaminants can be generated in the buildings themselves or transported from the outdoor, they can derive from human activities or be of natural origin. Appropriate air purification strategies are necessary to improve the quality of confined environments. They primarily concern the use of safe materials, the control of sources and the removal of emissions in proximity to them, ventilation and air exchange and its cleaning. Monitoring internal environmental conditions can promote the control and improve the indoor air quality, reducing the impacts on physical and psychological health of the occupants. After the COVID 19 pandemic, much more attention is paid to airborne particles and microorganisms responsible for respiratory diseases but there are still ample opportunities for intervention.
