We spend 90% of our time in residential and working closed buildings: home, office, school, supermarket, gym, etc.
The issue of air quality in confined spaces with particular reference to the correlation with comfort, health and - in the case of working environments - the productivity of the occupants has been the subject of increasing attention for some years.
The WHO itself has recognized that indoor pollution is a major environmental risk, whose main causes lie, on the one hand, in the large number of pollutant sources present in living and working environments, and on the other in the reduction of ventilation rates, generally related to energy saving reasons.
Indoor Air Quality is the environmental parameter that allows us to know this form of pollution and to prevent it in order to increase the living comfort and the safety and healthiness of the environment.
It is an index of evaluation of indoor environments that is determined through the detection, processing, analysis and evaluation of a set of variables such as temperature, humidity, brightness, presence of volatile organic compounds, particulate matter, radon gas, carbon monoxides and dioxides, airborne mold, proliferation of fungal colonies and concentration of chemical pollutants (VOC) found in confined living environments.
The monitoring activity generates precise quantitative indices developed by an international protocol:
