Indoor Environments Association Podcast

Presented by the Indoor Environments Association (IEA), The Indoor Environments Project is the podcast that takes you beneath the surface of radon, vapor intrusion, and indoor air quality. We explore the science, stories, ethics, and standards shaping the built environment—from homes to workplaces and everything in between.

Each month, we sit down with leading experts, seasoned professionals, and sharp thinkers to tackle the industry's most pressing challenges, uncover historical milestones, and imagine what’s next for indoor environmental health.

Whether you're a seasoned professional, policy advocate, or just curious about the air you breathe, this podcast delivers insight, practical knowledge, and a few surprises along the way.

📅 New episodes drop the 4th Wednesday of every month.
Subscribe today and join the conversation on the spaces we live, work, and thrive in.
