The recently updated Energy Performance of Buildings Directive (EPBD) is a pivotal legislative framework aimed at improving the energy efficiency of buildings across the European Union. While its primary focus remains on energy savings and decarbonization, the revised EPBD now formally recognizes the crucial link between energy performance and Indoor Environmental Quality (IEQ). This update requires member states to address IEQ in their national legislation, ensuring that energy-efficient buildings also support the health, comfort, and well-being of their occupants.

GO AQS, a leading advocate for universal indoor air quality standards, is proud to announce that its abstract has been accepted for a poster presentation at the 2025 Clean Indoor Air for ALL Conference. The event, hosted by the Clean Air Society of Australia and New Zealand (CASANZ), will take place from Monday, October 13th to Wednesday, October 15th, 2025, at the Amora Riverwalk Hotel Melbourne.

This session served as a crucial follow-up to our initial discussion on environmental pollutants, as we previously ran out of time to cover all the necessary ground. In today's meeting, we delved into the specifics of index breakpoints for ozone, nitrogen dioxide, and radon. Ozone (O3) Proposed GO IAQS Index: The proposed index tiers for ozone are 0 to 50 parts per billion (ppb) for "good," 51 to 100 ppb for "moderate," and 101 to 300 ppb or more for "unhealthy".

GO AQS is proud to announce that its abstract has been accepted for an oral presentation at the highly anticipated Indoor Environments 2025 Radon and Vapor Intrusion Symposium. This international event, gathering experts and professionals from around the world, will take place in Fort Worth, Texas, from October 26 – 29, 2025. Representing GO AQS and delivering the oral presentation will be 

During the 1st GO IAQS Index Breakpoints meeting, discussions focused on proposed breakpoints for various pollutants based on survey results, comparisons with existing standards, and feedback from attendees. The meeting aimed to cover results, compare them with existing breakpoints, and gather comments on specific pollutants, with a focus on PM2.5, Carbon Dioxide (CO2), Carbon Monoxide (CO), and Formaldehyde. PM2.5 (Particulate Matter 2.5 microns)

PM2.5 CO2 CO CH2O O3 NO2 Radon Conclusion The results presented below are based on a questionnaire distributed to participants from the GO AQS members list. The survey, conducted using Google Forms, was open from May 15th to June 15th, 2025. PM2.5 The GO IAQS Index Breakpoints Survey, with a total of 40 participants, indicated strong support for the proposed PM2.5 breakpoints, with 85% of respondents in agreement.

As we move significantly closer to the final V1.0 release of the white paper, this latest update incorporates a substantial volume of revisions and refinements after the working groups discussions. To accurately reflect this major leap forward in development and the extensive changes implemented, we are updating the document version directly from v0.12 to v0.80. This jump underscores the significant progress made and brings us considerably nearer to the definitive version.

We're excited to share an insightful upcoming webinar organized by inBiot that dives deep into the crucial topic of Indoor Air Quality (IAQ): "From Data to Impact: Defining a Common Language for Indoor Air Quality." This webinar promises to be an engaging session for anyone interested in understanding, interpreting, and ultimately improving the air we breathe indoors. By establishing a common language around IAQ data, we can foster better collaboration and drive more impactful solutions for healthier indoor environments.

The GO AQS ventilation working group convened on April 4, 2025, to discuss various aspects of ventilation in buildings and recommend the best solutions and practices in order to achieve good indoor air quality. Prioritizing Indoor Air Quality and Energy Conservation The session began with a survey of members' perspectives on the importance of indoor air quality and energy conservation. Encouragingly, all members agreed that indoor air quality in buildings is of maximum importance.

The Filtration Working Group of the GO AQS convened to discuss recommendations for filtration given the multitude of existing options. Filtration Technologies and Their Effectiveness A poll on trusted filtration technologies revealed a broad consensus on mechanical filtration (HEPA and MERV filters) due to their proven performance according to their specifications. Similarly, absorbent filtration using activated carbon was generally trusted for gas removal.

The Radon Working Group, a part of the Global Open Air Quality Standards initiative, convened to discuss and establish recommendations for indoor radon levels. This session built upon previous discussions focusing on other indoor air pollutants such as particulate matter, carbon dioxide, carbon monoxide, formaldehyde, and nitrogen dioxide. The objective of this working group is to develop globally applicable standards for radon.

The Ozone Working Group (WG) convened on April 2nd, 2025, as part of the Global Open Air Quality Standards initiative, to delve into the specifics of incorporating ozone (O₃) into indoor air quality guidelines. Following previous discussions on particulate matter, carbon dioxide, and carbon monoxide, this session focused on the unique challenges posed by ozone, with participants raising important points regarding the establishment of target and ceiling limits, and appropriate measurement units.
