The Indoor Air Quality Indicator (IAQ) is based on the RESET AIR INDEX, and allows to communicate in a simple way, on a 0-100 scale, the indoor air quality of a space. It allows to check, in real time and in a simple way, the overall air quality in a specific space. The IAQ indicator also includes recommendations for improvement and allows to know the evolution of the air quality during the selected period of time.
It is calculated from continuous monitoring data of the most relevant parameters for the definition of indoor air quality, such as CO₂, TVOC and PM2.5, and their combined impact.
It takes into account the cumulative effect of exposure over time, assessing the sum of concentrations of the different pollutants and taking into account the objectives of the RESET AIR Standard, as well as the know-how developed by inBiot on the behavior of specific CO₂, TVOC and PM2.5 sensors in a monitoring device, and the health impact of the different parameters combined under certain conditions of use of indoor spaces.
The indicator defines 6 categories of impact on indoor air quality: bad (0-16%), inadequate (17-32%), fair (33-48%), moderate (49-65%), good (66-83%) and excellent (84-100%), as calculated by an algorithm based on CO₂, TVOC and PM2.5 concentrations.
