Reflecting on a Year of Air Quality Conversations: Milestones, Themes, and Looking Forward
As we wrap up a year of the Air Quality Matters podcast, it feels like a moment to pause, reflect, and appreciate how far we’ve come. In this 48th episode, I want to share a bit of the journey—what it takes to produce this podcast, the key themes that emerged, and a few predictions for what lies ahead in 2025.
The Making of Air Quality Matters
When I began this podcast over a year ago with Max Sherman as our inaugural guest, I had no idea it would evolve into such a fulfilling project. Over 37 interviews, 10 solo episodes, and countless hours, this podcast has grown beyond the original concept. The feedback I receive, from professionals to students, reaffirms its value as a unique, in-depth resource on air quality and ventilation.
Producing each episode involves a mix of research, preparation, and a commitment to active listening—something I’ve had to refine with each conversation. From initial meetings to editing and final touches, each episode requires substantial time, often three-quarters of a day. I think this level of commitment is what makes the podcast a learning experience not just for listeners but also for me as a host.
Key Themes from the Year
Over the year, several themes have crystallised through over 670,000 words spoken. Forming a foundation for the podcast’s purpose and mission:
Balancing Energy Efficiency with Health The interplay between energy efficiency and ventilation has been a consistent focus. Throughout the episodes, guests like Max Sherman and Cath Noakes have emphasised the need to align energy goals with health priorities. We’re in a phase where ventilation and air quality are intrinsically linked to energy-efficient building design, ESG standards, and sustainability.
Health-Centric Building Standards The pandemic propelled indoor air quality into the public health spotlight. As we discussed with guests, CO2 monitoring and indoor air standards are becoming commonplace, reinforcing the idea that air quality isn’t just about comfort but health and safety. This shift is driving new building standards focused on human health, a trend I expect to continue in 2025.
Accessibility and Affordability of Air Quality Solutions Guests like Richard Corsi and Douglas Booker highlighted the importance of making air quality solutions accessible to everyone. Innovations like the DIY Corsi-Rosenthal box, which provides affordable filtration solutions, have shown that simple ideas can bring substantial change. Conversations with experts underscore that making air quality improvements affordable is critical, especially for vulnerable communities.
Data-Driven Policy and Standards Robust data is essential to shaping policies that promote healthy indoor environments. This year saw a push towards data-informed decisions in air quality standards, driven by real-time monitoring and empirical evidence. This approach allows us to tailor policies to regional and building-specific needs—a necessity in sectors like social housing.
Air Quality as a Social Justice Issue Through discussions with Sarah West, Douglas Booker, and others, it’s evident that air quality inequities often mirror social inequities. Low-income and marginalised communities are disproportionately impacted by poor air quality. Addressing these disparities is not only a technical challenge but also a matter of social justice, a point that resonated deeply across multiple episodes.
Interdisciplinary Collaboration Air quality isn’t a challenge that one sector can solve alone. An interdisciplinary approach, as championed by figures like Sir Stephen Holgate, is essential. This year, we explored various facets of air quality—from building science to social policy—illustrating the need for a collaborative effort to improve indoor environments worldwide.
Looking Ahead to 2025
So, where do we go from here? If I had to predict, 2025 will see a continued focus on health-centric standards, driven by deeper research linking air quality to cognitive and physical well-being. Advances in monitoring technology will offer more detailed insights, helping us evaluate building performance in real-time rather than just by compliance standards. I also anticipate greater government engagement as policies begin to reflect the interconnectedness of air quality and public health.
On a practical note, we’re planning to take the podcast on the road. Meeting experts in their environments will add a fresh dimension, and moving into video content is on the horizon, allowing us to reach an even broader audience. I’m eager to hear your feedback on potential guests and topics—this podcast is as much your community as it is mine.
Thank you for being a part of this journey. Your support and interest keep this initiative alive, and with partnerships and community engagement, we’re building a vital resource for the air quality and ventilation sector. Here’s to another year of insights, learning, and positive change.
