Green Leases, Decarbonization & The Hidden Influence of Tenants with Jon Lemmond

Most sustainability conversations focus on building owners. But what about tenants? In this episode, Marcus Hazelwood sits down with Jon Lemmond of JLL to discuss how tenants can influence building performance, energy efficiency, and decarbonization outcomes, even when they don't control the building's major systems. From New York City's Local Law 97 to green lease structures, submetering, shared investment strategies, and landlord-tenant collaboration, Jon explains how organizations can unlock sustainability opportunities that are often hiding in plain sight. The conversation explores why communication, measurement, and aligned incentives may be more important than any individual technology. In This Episode: *  Why decarbonization efforts often stall in leased spaces  *  The "split incentive" challenge between landlords and tenants  *  How green leases can create shared financial and environmental value  *  Why submetering and data transparency matter  *  Local Law 97 and the rise of building performance standards  *  Tenant strategies for reducing Scope 1, 2, and 3 emissions  *  How leasing decisions influence long-term building performance  *  Why communication may be the most powerful sustainability tool available  Key Takeaway Many tenants assume they have little influence over building performance. The reality is often the opposite. The organizations achieving the best outcomes are the ones engaging landlords early, aligning goals, sharing data, and treating sustainability as a partnership rather than a requirement.  🎧 Subscribe to Clear Haze Exchange on Apple Podcasts, Spotify, YouTube, Amazon Music, and all major podcast platforms.

The Hidden Energy Problem Inside Laboratories | Sustainable Science with Ila Summitt

Laboratories are some of the most resource-intensive buildings in the world. But many organizations still underestimate the operational, energy, and waste impacts happening inside research environments every day. In this episode of Clear Haze Exchange, Marcus Hazelwood speaks with Ila Summitt, molecular biologist and Sustainability Certification Manager at My Green Lab.  With more than 20 years of experience in academic, biotech, and clinical laboratory settings, Ila shares how labs can improve sustainability without compromising scientific integrity. This conversation explores: *  why laboratories can consume 10x more energy than office buildings  *  the hidden operational impact of fume hoods and ultra-low freezers  *  how behavioral change drives measurable sustainability improvements  *  why waste and energy use in labs are often overlooked  *  how universities and biotech organizations are approaching sustainable science  *  the role of culture, leadership, and operational awareness  *  and how programs like My Green Lab Certification and the International Freezer Challenge are creating measurable global impact  A key takeaway from this episode: ➡️ Sustainability in laboratories is not just about carbon reduction—it’s about operational intelligence, efficiency, and long-term performance. This is a must-listen for professionals involved in: *  laboratory operations  *  higher education  *  biotech and life sciences  *  facilities management  *  sustainability strategy  *  healthcare research  *  and high-performance building operations

Why Sustainable Buildings Still Underperform | Hidden Systems with Umesh Atre

Why do so many buildings begin with strong sustainability goals… yet struggle to deliver long-term performance? In this episode of Clear Haze Exchange, Marcus Hazelwood speaks with Umesh Atre, a sustainability leader with over two decades of experience across LEED, WELL, energy modeling, lifecycle cost analysis, and building performance strategy.  Currently Sustainability Lead at Parkhill, Umesh has worked on more than 200 high-performance building projects and brings a systems-level perspective to sustainable design, occupant wellbeing, and operational success. This conversation explores: *  why project location and building orientation matter more than many teams realize  *  where sustainability intent often breaks down during design and construction  *  why lifecycle cost analysis is frequently introduced too late  *  the role of commissioning and performance verification in protecting design intent  *  how invisible operational systems shape occupant wellbeing  *  why certifications alone don’t guarantee real performance  *  and how long-term thinking must become part of project culture  Umesh also discusses the importance of integrated design, stakeholder alignment, and designing buildings that continue performing long after the project team leaves. A powerful conversation for architects, engineers, owners, operators, sustainability professionals, and anyone interested in the future of high-performance buildings. 🎧 Listen now on Apple Podcasts, Spotify, YouTube, and all major platforms.

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.

The Hidden Risk Behind the Data Center Boom: Why Operations Matter More Than You Think

The data center boom is accelerating faster than most industries can keep up with. But behind the headlines around AI, cloud growth, and billion-dollar investments, there’s a critical question that often gets overlooked: Who is actually operating these facilities and are we prepared? In this episode of Clear Haze Exchange, host Marcus Hazelwood sits down with Tom Melton, a facilities and operations engineer with over 30 years in the trades and 15+ years in mission-critical data center environments. Tom shares a candid, ground-level perspective on: *  The growing shortage of skilled engineers in data centers  *  Why understaffing creates hidden operational risk *  The gap between training programs and real-world readiness *  Misconceptions about data centers, power, and public impact *  Why trades and hands-on expertise are critical to sustaining AI infrastructure  As data centers scale from 24 MW to 300+ MW facilities, the challenge is no longer just design or capital, it’s execution, operations, and people.  This conversation is a must-listen for: *  Architects and design professionals  *  Owners and developers  *  Investors and policymakers  *  Engineers and operators  Because the future of AI infrastructure depends on more than innovation, it depends on the people who keep it running.
