Effective communication is the missing link. Whether it’s ventilation, air quality, or construction standards, how we communicate technical subjects can determine whether innovations succeed or fade into obscurity.

When we talk about improving air quality in buildings, we often focus on technology, materials, and standards. But one of the biggest challenges in both retrofit and ventilation is the skills gap—finding the right people with the right knowledge to do the job properly.

Welcome back to Air Quality Matters. This week, it's just me, and I wanted to take some time to discuss a few key topics that have been making waves in indoor air quality. From an exciting new conference in India to a new venture with Air Quality Matters consultancy, and finally, to the ever-relevant issue of damp and mould, there’s much to cover.

Mould is an ever-present challenge in buildings, especially in social housing, yet the way we talk about it is often overly simplistic. It’s either there or it isn’t, and the goal is always to eradicate it. But the reality is much more nuanced.

The discussion quickly expanded beyond solely focusing on air quality. Paweł Wargocki emphasised the need for a holistic approach, considering thermal comfort, acoustics, and lighting alongside air quality. He highlighted that while we've long understood the effects of indoor environments on adults, we're now gaining clarity on the specific needs of children.

Plum's journey to founding the Safer Air Project is deeply personal and professionally informed. With a background in health policy and public affairs, specialising in cancer and social inclusion in terminal illness policy, Plum has a unique understanding of the challenges faced by those with chronic health conditions.

The built environment is in constant flux, grappling with the intertwined challenges of sustainability and indoor air quality (IAQ). We know that IAQ often rides on the coattails of sustainability initiatives, but where exactly is the sustainability sector today, and what lessons can we learn from its journey to inform the burgeoning IAQ movement?

In the world of construction, we often find ourselves caught in the whirlwind of modern building practices, overlooking the vast wealth of knowledge embedded in our existing building stock and the professionals who work with them.

We often focus on aspects of indoor environmental quality: temperature, light, and air Quality. But what about the soundscape of our buildings?

On this episode of Air Quality Matters, I sat down with Jack Harvie-Clark , founder of Apex Acoustics Ltd and a leading voice in the acoustics field

I had a fascinating conversation with Nels Anderson , Business Director at TSI Incorporated , a company renowned for its high-precision measurement technology. We delved into the world of "near-reference grade" environmental sensors, a fascinating middle ground between low-cost sensors and the gold-standard research-grade equipment used by academics.

This week we’re diving into a fascinating conversation with Joakim Lindh, Head of Strategic Growth at Airthings. Joakim’s career has spanned the evolution of connected devices, from his beginnings at Texas Instruments to his current role at Airthings

I had the pleasure of speaking with Maria Figols, Chief Scientific Officer and co-founder of InBiot. Maria brings an impressive experience in healthy, sustainable, and efficient building design. As a technical architect and building engineer with a master's in building biology, Maria’s expertise in connecting technology and human health is evident in her work at InBiot

John McKeon, CEO of Allergy Standards Limited and Principal at the iAIR Institute. John’s unique journey—from working as an emergency room doctor in Dublin to founding an international standards and certification body—offers a fascinating perspective on the links between human health and the built environment.

I sat down with Tim Sharp, Head of Architecture at the University of Strathclyde, to discuss ventilation in the UK and how well our homes and buildings are equipped to handle modern air quality demands.

In episode 50 of Air Quality Matters, I had the pleasure of sitting down with Peter Rankin , Head of Energy and Environmental Standards at the Health and Safety Executive (HSE) in the UK.

On World Ventilate Day, we’re reminded of the critical link between ventilation and healthy indoor spaces. As we spend more time indoors, the quality of the air we breathe is increasingly vital—not just for our physical health but also for productivity and cognitive function.

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.

This week on the Podcast, we take a closer look at the work of Change the Air Foundation and Brandon Chappo , a non-profit organization dedicated to improving indoor air quality by addressing the issues of dampness, mould, and water damage in U.S. buildings.

In this episode of Air Quality Matters, I had the pleasure of sitting down with Michael D. Ham , a passionate advocate for a holistic approach to air quality, technology design, and human health. Our conversation touched on the important role our built environments play in shaping our well-being, particularly in the evolving landscape of work-from-home culture.

In our latest episode of Air Quality Matters, I sat down with Tom Hetherington Heywood , the MVHR Department Manager at 21 Degrees , to discuss the intricacies of ventilation systems, the philosophy that drives their team, and why we need to shift our thinking toward performance-focused design.
