Recognising the current limitations of the existing air quality indices (AQIs) and the diverse national and international regulation across many countries, we are presenting the Global Open Air Quality Standards (GO AQS) a novel framework which confronts the global need for a unified, transparent, and science-backed benchmark for clean air indoors. It was built upon a rigorous analysis of breakpoints for each pollutant, drawing extensively on scientific literature and carefully assessing their specific health implications across various concentration levels.
The GO AQS can be classified into two tiers, namely GO IAQS Starter and GO IAQS Ultimate. The first is designed to be the first step for improving indoor air quality (IAQ) focusing on mitigating financial and logistical barriers in developing nations and underserved communities. It targets PM2.5 and CO2 pollutants which can be monitored effectively utilizing widely available low-cost air quality sensors. On the other side, GO IAQS Ultimate offers an improvement to building performance and enhanced occupant health protection by tackling effectively elevated concentration levels of pollutants (e.g. O3, CO, CH2O, NO2, and Rn) and ensuring compliance with more stringent regulatory guidelines.
Finally, the GO IAQS Score an additional key feature of GO IAQS, also known as the AQI, is a simplified index established for clear public communication. It utilizes a color-coded health risk categories system, presenting air quality information in an easy and understandable way.
