Clear Haze Exchange is an interview-led podcast focused on simplifying sustainability while uncovering the hidden systems, decisions, and long-term impacts shaping our built environment and energy future.

Hosted by Marcus Hazelwood, an energy engineer with 15+ years of experience in sustainability and energy efficiency consulting, the podcast has evolved across two seasons:

Season 1 focused on breaking down the fundamentals—making energy efficiency, building systems, and sustainability concepts more accessible and practical for a wide range of listeners.
Season 2 builds on that foundation, diving deeper into the systems-level thinking behind sustainability—exploring how decisions in design, operations, policy, and business strategy create long-term outcomes.

Each episode features thoughtful conversations with industry leaders, engineers, architects, researchers, and decision-makers who are actively shaping the future of sustainability. From building performance and infrastructure to sustainable chemistry and organizational mindset, Clear Haze Exchange connects ideas across disciplines to provide real-world insight.

This podcast is for professionals and curious minds alike, those who want to better understand not just what sustainability is, but how it actually works in practice.

If you're interested in smarter investments, better systems, and meaningful progress, you're in the right place.
