Mass Timber Beyond the Hype: Systems, Tradeoffs, and Real-World Constraints with Vaughn Horn

Mass timber is gaining momentum across the built environment—but how much of the conversation is grounded in reality?

In this episode of Clear Haze Exchange, Marcus Hazelwood speaks with architect Vaughn Horn about the hidden systems behind mass timber design, decision-making, and performance. 

Together, we explore:

• Why mass timber is gaining traction in higher education and research environments 
• The role of life cycle analysis, embodied carbon, and long-term value 
• Structural limitations and the importance of building modules 
• Fire rating requirements and the impact of code on design feasibility 
• MEP coordination challenges and why early integration is critical 
• Supply chain realities, procurement timelines, and schedule risks 
• How architects and owners should think about tradeoffs between cost, carbon, and performance 

This conversation highlights a key theme of Season 2:
Sustainability decisions are only as strong as the systems behind them.

Whether you’re an architect, engineer, owner, or investor, this episode will challenge assumptions and provide a clearer understanding of what it actually takes to deliver high-performance, sustainable buildings.

What is Clear Haze Exchange?

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.
