The GO AQS white paper has undergone a significant transformation from version v0.81 to v0.90, reflecting a period of intensive development and refinement. This latest iteration, building upon the foundational concepts of its predecessor, introduces a multitude of additions and corrections that enhance the clarity, scope, and precision of the framework.

A primary focus of this update is the GO IAQS Score, with detailed revisions to its breakpoints and the underlying rational for their proposed values. Furthermore, a significant new addition is a dedicated chapter on good indoor air quality (IAQ) practices, offering practical guidance and recommendations for maintaining healthy indoor environments, which we will continue updating.

Changelog:

• GO IAQS Score includes proposed limits for the breakpoints of the pollutants and rational .
• Updates on the localization of the GO IAQS Score.
• New chapter about good IAQ practices.
• Minor text corrections and clarifications: We’ve refined the text in various sections to improve clarity and readability.
• Appendix D – Index comparison.
• Updated member list.
