What happens when 46 research institutes from 21 countries join forces to tackle one of our most pressing indoor environmental challenges? A groundbreaking framework that's already changing how we approach air quality in our homes.

The Annex 86 project represents a fascinating convergence of engineering, chemistry, and public health expertise focused on creating energy-efficient indoor air quality management strategies for residential buildings. Over five years, this international team has developed innovative approaches to understanding, measuring, and improving the air we breathe at home without compromising energy efficiency.

During our conversation with project leader Jelle Laverge and task leaders Gaëlle Guyot and Marc Abadie, we explore how this collaborative effort has evolved from theoretical research into practical applications. The team shares insights on their development of comprehensive air quality metrics that are already being adopted by ASHRAE standards, the creation of the Pandora database cataloging thousands of indoor pollution sources, and the promising frontier of smart materials like Metal Organic Frameworks that can selectively absorb harmful pollutants such as formaldehyde.

Perhaps most intriguing is their concept of a "rating ecology" rather than just a rating system – acknowledging that effective indoor air quality management requires a complex, interconnected framework of tools and approaches. This ecological perspective allows for meaningful comparison between different technologies and strategies, from smart ventilation systems to advanced materials, helping designers and policymakers make informed decisions about improving our indoor environments.

Whether you're a building professional, policy maker, or simply someone concerned about the quality of air in your home, this episode offers valuable insights into how international collaboration is driving innovation at the intersection of health, comfort, and sustainability.
