In this episode, we sit down with Bart Cremers, Group Knowledge Consultant at Zehnder Group International, to explore one of the most critical—yet often overlooked—challenges in advancing indoor air quality: how industry and academia can collaborate more effectively.

Bart occupies a fascinating position, straddling the worlds of industry and research, product innovation and scientific rigour. With deep expertise in physics, renewable energy, data analysis, and business development, he has spent years translating fundamental science into real-world ventilation solutions—and feeding real-world performance data back into the research community.

The Central Question:

We already have the tools and knowledge to deliver clean, healthy indoor air. So why is there still such a persistent gap between what we know works in the lab and what actually happens in people's homes? And how can we unlock the enormous potential that exists when industry and academia work together properly?

Key Topics Discussed:

• The Two Silos: Why industry and academia often work on the same problems but from fundamentally different perspectives—and why bridging that gap is essential for progress.

• What Industry Brings to Research: Real-world performance data, field monitoring at scale, the ability to tell stories rather than just specs, and the crucial feedback loop between lab performance and lived experience.

• What Academia Brings to Industry: Scientific rigour, peer review, freedom to explore problems without immediate commercial pressure, and the discipline to ask—and answer—the right questions.

• The Speed Problem: Why academic research can take five or six years from conception to publication—and by that time, the technology being studied is often two generations out of date.

• The Performance Gap: Why so much academic research ends up measuring poorly installed or maintained ventilation systems—and what that means for our understanding of what good ventilation can actually achieve.

• Models vs. Reality: The critical importance of validating simulations and models with real-world data—and how industry can provide the field measurements academia desperately needs.

• The Minimum Becomes the Maximum: How regulations and standards, by nature, lag behind innovation—and why designing to minimum compliance is a race to the bottom that leaves everyone worse off.

• The Future: Ventilation as a Service: Why the shift from selling products to selling clean air and healthy outcomes could fundamentally transform the industry—and close the performance gap for good.

• Multifunctional Systems: The promise and peril of integrating ventilation with heating, cooling, and other building systems—and why we need to get the basics right first.

• Retrofit and Renovation: Why the next frontier isn't just new build, but bringing healthy indoor air to the billions of existing buildings—and why that requires a completely different approach.

• Citizen Science: The untapped potential of involving real people in real homes in the research process—not just as data sources, but as co-creators of the questions we need to answer.

This is a conversation about friction, opportunity, and the path forward. It's about recognizing that both industry and academia have blind spots—and that the only way to truly advance indoor air quality is to work together, with mutual respect, shared goals, and a willingness to learn from each other's strengths.
