The Green Building Matters Podcast with Charlie Cichetti

The Green Impact Report Quick take: We've spent two decades pulling concrete out of buildings to cut carbon, and quietly lost the thermal mass that kept rooms comfortable. Mick Dunn's fix rides in on something every project already installs: the ceiling tile. 🎓 Meet Your Fellow Sustainability Champion Mick Dunn is the Product Manager for Energy Saving Ceilings at Armstrong World Industries, where he brings phase change materials into everyday buildings. A Melbourne native, he studied construction management at RMIT, came to the US on an exchange at the University of Florida, and stayed. He spent his early career in commercial construction in Maine, then ran his own companies for 15+ years, first in commercial solar thermal and then developing phase change materials. One of those products started in his garage and is now scaled by Armstrong. His 20+ years sit right where advanced thermal storage meets real-world job sites. 🌱 Breaking Ground on Better Building In this episode, Mick Dunn rethinks the most overlooked surface in the building: the one over your head. Key Insight #1: The ceiling becomes a thermal battery. The Challenge: Ceilings are bought for looks and acoustics. When it comes to energy, they're dead space. The Solution: Armstrong's Templok puts a quarter-inch gelled-salt phase change layer on the back of standard ceiling tiles. Mick calls it "ice packs in your ceiling." As the room warms, the material melts at room temperature, absorbs the heat, and lets it go later. ROI: Peak room temperatures drop 2–3°F with no change to how the ceiling looks. Install is the same crew, ladders, and trucks, so the storage gets "a free ride." Key Insight #2: Put back the mass we stripped out. The Challenge: Lightweight, prefab, low-concrete construction cuts embodied carbon. It also strips out the thermal mass that used to steady indoor temperatures. The Solution: Phase change material adds thermal mass without the weight. Because drop ceilings are easy to reach, it also retrofits into existing buildings with known comfort problems. ROI: Owners get "a new dial they can turn" on problem buildings. It eases peak HVAC loads, helps with peak shaving, and makes occupants more comfortable without replacing equipment. Key Insight #3: Your ceiling can qualify for a federal tax credit. The Challenge: Upgrades like this lose at the budget table because they look like a pure added cost. The Solution: Thermal storage is eligible for the federal investment tax credit, just like battery storage and ground-source heat pumps. ROI: Planned well, Mick says, the ceiling can end up costing less than a standard one. That's alongside Armstrong's Declare labels, EPDs, HPDs, ceiling take-back program, and its new lowest-embodied-carbon tile. 💬 Sustainable Soundbite "The chief goal of a building should be for it to be sustainable to live in, heal in, and work in." – Mick Dunn 💚 Your Green Building Action Plan Transform your next project with these steps: This Week: List the buildings in your portfolio with the most comfort complaints, especially ones already due for a ceiling refresh. Those are your pilot candidates. This Quarter: Ask your tax advisor or incentives consultant whether ceiling-integrated thermal storage qualifies for the federal ITC on an upcoming project. Run the numbers before the ceiling spec is locked. This Year: Make thermal storage, acoustics, and thermal comfort part of your master spec and decarbonization roadmap. Then join your local USGBC chapter, as Mick did, to find the people already solving these problems. 🔗 Connect & Learn More 🌿 Access full episode resources: https://www.gbes.com/podcast 🗒️ Read the transcript: here 👩🏻‍💻 Connect with Mick Dunn: Website: Armstrong World Industries, Inc.

The Green Impact Report Quick take: What if a coating 1 millimeter thick could insulate like a thick layer of conventional material, and you could prove it without waiting a year on a pilot? Nathan Kegel spent 20-plus years in energy modelling. Now he's at a materials science startup, building the simulation engine that tests its products before they ever reach a roof. Meet Your Fellow Sustainability Champion Nathan Kegel leads energy services at Nanotech Materials. He grew up outside Green Bay, Wisconsin, working on a neighbor's sweet corn farm (and he's still a Packers fan). He studied at the University of Minnesota and started out designing HVAC and plumbing systems. He soon moved into energy simulation, the part of the job he found more interesting. Over about 20 years he worked on some of the early net zero and LEED Platinum lab projects in California and built building performance teams at architecture and engineering firms. He also spent roughly a decade, on and off, at IES, helping bring advanced building simulation software to North America. He's based in the Twin Cities and reads philosophy and the classics for fun. 🌱 Breaking Ground on Better Building In this episode, Nathan Kegel rethinks how we insulate buildings and how we prove that new materials work: Key Insight #1: Insulation doesn't have to mean thickness The Challenge: The industry rates insulation by R-value, and thickness is part of that calculation. More resistance has meant more material, more depth and more weight. Nathan half-jokes that R-value is "the bane of my existence." The Solution: Nanotech Materials puts a silica-based particle into coatings like acrylics and epoxies. Nathan says the particle has a K-value (thermal conductivity) on par with aerogel, without aerogel's brittleness. Applied about 1 millimeter thick on a roof, the coating can essentially stop heat conduction through it. ROI: According to Nathan, the roof product is rated for Florida's 200 mph impact standard. A related spray-on coating, developed with the state of California, protects timber from wildfire and resists heat up to 1,800°C with very low smoke. You get thermal performance and resilience from one thin layer. Key Insight #2: Stop running endless pilots The Challenge: A startup can't coat a roof and wait a year to see if it worked. As Nathan puts it, "you might not be in business a year." Slow field pilots stall innovation across the industry. The Solution: One of Nanotech's co-founders built a new physics engine from scratch rather than relying on older simulation code. It has been validated under ASHRAE Standard 140. Nathan is bringing it to market, starting with services and eventually opening the full platform to project teams. ROI: Validated simulation means faster, more confident decisions about new materials. Teams can predict performance instead of waiting for it. Key Insight #3: Coat the pipe instead of jacketing it The Challenge: Traditional pipe insulation needs aluminum-jacketed systems that take a lot of labor to install. Moisture can also get trapped between the insulation and the pipe, which causes corrosion under insulation (CUI). The Solution: A coating a couple of millimeters thick, adhered directly to the metal, stops heat transfer without the jacket. ROI: Nathan says this greatly reduces labor costs and nearly prevents corrosion under insulation, so the system costs less upfront and lasts longer. 💬 Sustainable Soundbite Options "If you really want to make the world a better place, define what that better place looks like and then work toward it, and you will be rewarded. Yes, there's going to be setbacks, but just be relentless in that pursuit of learning more and more." – Nathan Kegel 💚 Your Green Building Action Plan Transform your next project with these steps: This Week: Do the jargon check Nathan recommends. Before your next presentation to an owner or your boss, figure out who the audience is, list your technical jargon, and rewrite your pitch at their level. This Quarter: Find one place where thickness drives your current spec, such as roof insulation, pipe jacketing or a retrofit with tight clearances. Ask what thin-film or high-performance coating alternatives would do to cost, labor and durability. This Year: Start with the end in mind. Don't ask "What will building design look like in 2030?" Define what you want your projects, team or firm to look like, then work backward and use energy modeling to test the path before you commit. 🔗 Connect & Learn More 🌿 Access full episode resources: https://www.gbes.com/podcast 🗒️ Read the transcript: here 🧩 Connect with Nathan Kegel: LinkedIn: https://www.linkedin.com/in/nathankegel/ Learn more about Nanotech Materials: https://nanotechmaterials.com/ 💚 Join the Green Building Movement: https://www.greenbuilding.news/subscribe 💡 Want More Green Building Insights?

The Green Impact Report Quick take: LEED used to be the strategy. Now it's one of maybe 20 tools. Marianna Palmour went from reviewing LEED projects to building a corporate ESG program from scratch at a 5,000-person firm, and she explains why your biggest clients' Scope 3 targets are about to become your problem. 🎓 Meet Your Fellow Sustainability Champion Marianna Palmour leads corporate sustainability at Salas O'Brien, an engineering and technical services firm with more than 5,000 people. She grew up on Lookout Mountain in northwest Georgia, studied architecture at Georgia Tech, and got into green building early. She took the LEED exam straight out of school and served as vice president and past president of USGBC's Emerging Green Builders. From there she worked at Sustainable Options and then Epstein Group, where she was a LEED third-party reviewer and built out a portfolio and ESG service line. She went back to Georgia Tech for an MBA in entrepreneurship, which made her a "double Jacket." While there she was a fellow with the Ray C. Anderson Center for Sustainability, focused on inclusive design. When Salas O'Brien acquired Epstein Group, she was asked to build the ESG program from the ground up. 🌱 Breaking Ground on Better Building In this episode, Marianna Palmour shows how sustainability moves from the building to the boardroom: 💡 Key Insight #1: Double materiality beats copying the competition The Challenge: Companies often set sustainability goals by looking at what peers are doing, or by asking only the people at the top. The Solution: Run a materiality assessment that asks every stakeholder: communities, investors, the board, clients and suppliers. Then look at it in both directions ("double materiality"): how sustainability issues affect the business, and how the business affects the environment. ROI: The strategy fits your own values, your regulatory exposure (Local Law 97 in New York, California's ESG disclosure rules) and the people you actually answer to. You don't spend money chasing someone else's priorities. 💡 Key Insight #2: Your clients' Scope 3 is now your compliance problem The Challenge: Smaller firms and service providers assume EU rules and emissions reporting only apply to big multinationals. The Solution: Get ready now. Big global clients have to report Scope 1, 2 and 3 emissions, so they're pushing supplier codes of conduct and emissions reporting down the supply chain. That includes consultants. Marianna's simple test: Scope 1 is fuel you burn yourself, Scope 2 is energy someone else produces for you, and Scope 3 is everything upstream and downstream. ROI: A $20K job might not get noticed. Millions in work puts you in a client's Scope 3 footprint. Firms that can sign off on supplier standards and report their emissions keep those relationships and stay eligible for the work. 💡 Key Insight #3: Make the business case in two languages The Challenge: Green policies usually get written one building or one office at a time, and leadership sees them as a nice-to-have. The Solution: Early in her career, Marianna took the Georgia-Pacific tower in downtown Atlanta (over a million square feet) through one of the first big LEED EBOM v2009 certifications. It was the first time she had to convince a C-suite that operational changes were right on values and on economics. She now brings that approach to whole portfolios, turning energy, water and indoor air quality strategies into standards that work across cities, countries and regulations. ROI: Policies adopted across the whole organization save money and resources everywhere at once, not just in one showcase building. 💬 Sustainable Soundbite "It's amazing what you can do if you are not afraid and you lean on your community." – Marianna Palmour ⬇️ Your Green Building Action Plan Transform your next project with these steps: This Week: Pull the supplier codes of conduct from your top three clients and compare them with your own policies. If you can't attest to them today, find out why. This Quarter: Run a light materiality assessment. Survey employees, key clients, suppliers and leadership about which sustainability issues matter most to them, and look at both sides of double materiality. This Year: Take one strategy that worked on a single building (an energy, water or IEQ policy) and write it up as a standard for your whole portfolio or company. Then start tracking the Scope 3 data your biggest clients will eventually ask for. 🔗 Connect & Learn More 🌿 Access full episode resources: https://www.gbes.com/podcast 🗒️ Read the transcript: here 🌎 Connect with Marianna Palmour: Website: https://salasobrien.com/ LinkedIn: https://www.linkedin.com/in/marianna-palmour/ 💚 Join the Green Building Movement: https://www.greenbuilding.news/subscribe 🔋 Want More Green Building Insights?

📝 The Green Impact Report Quick take: The future of high-performance buildings isn't necessarily about adding more technology — it's about making smarter decisions. Mechanical engineering leader Dale Garfield breaks down why fundamentals, heat pumps, renewable-ready infrastructure, and owner-focused design matter as buildings move toward a lower-energy future. 🤝 Meet Your Fellow Sustainability Champion Dale Garfield's path to building engineering started somewhere unexpected: the United States Marine Corps. After serving as a combat engineer — including a deployment to Iraq — Dale returned to Wisconsin and began studying civil engineering technology at Mid-State Technical College. An instructor encouraged him to take the next step, eventually leading him to Milwaukee School of Engineering's Architectural Engineering Program. Since graduating, Dale has built a career spanning engineering firms, mechanical contractors, design-build environments, and integrated architecture and engineering. Today, he is a Mechanical Engineering Leader at EUA, where his experience touches projects ranging from K-12 schools and manufacturing facilities to corporate headquarters and shipbuilding facilities. Along the way, Dale also earned an executive MBA to strengthen the business and leadership side of his technical career. His approach to buildings is refreshingly straightforward: understand what matters to the owner, remember the fundamentals, and don't make a system more complicated than it needs to be. 🌱Breaking Ground on Better Building In this episode, Dale shares a practical engineer's perspective on making buildings more efficient without losing sight of the people who have to own, operate, and maintain them. 📚 Key Insight #1: High-performance design starts with the owner—not the technology. The Challenge: Sustainability can become an exercise in adding technology without first asking what the owner actually wants, needs, or can support. Budgets, operational capabilities, energy goals, and long-term priorities vary significantly from project to project. The Solution: Dale starts with the owner's expectations and builds efficiency into the design from there. That can mean variable frequency drives, condensing boilers, high-efficiency chillers, heat pumps, and other proven strategies — without overengineering the building simply for the sake of complexity. ROI: Owners get efficient systems aligned with their real operational and financial needs. Just as importantly, they get buildings that work and systems their teams can maintain. 🚀MKey Insight #2: Heat pumps can push efficiency forward—but mechanical systems can't get buildings to net zero alone. The Challenge: Engineers can improve heat recovery, heat pumps, chillers, and HVAC performance, but there's a physical limit to how far mechanical efficiency can go. As Dale points out, engineers still have to work within the fundamentals of thermodynamics. The Solution: Combine increasingly efficient mechanical systems with onsite renewable energy. Dale is also seeing projects prepare for the future by designing structural and electrical infrastructure that can support photovoltaic arrays later — even when solar isn't part of the initial construction. ROI: Solar-ready and renewable-ready infrastructure gives owners flexibility. Instead of paying for every sustainability measure on day one, they can create a building capable of adapting as economics, technology, energy priorities, and requirements change. 🧠 Key Insight #3: The best engineering solution is often the simplest one that actually works. The Challenge: Engineers can be tempted to solve problems with increasingly complicated systems. Complexity can create its own problems when owners and facilities teams eventually have to operate, troubleshoot, and maintain those systems. The Solution: Dale returns to a lesson he learned early in his career: keep it simple and remember the fundamentals. He also believes engineers need to stick with problems when they occur instead of distancing themselves when a project gets difficult. ROI: Straightforward, maintainable systems can reduce operational headaches while giving owners something arguably even more valuable: confidence that their engineering team will remain engaged when challenges arise. 💬 Sustainable Soundbite Options "Keep it simple. Remember the fundamentals. You can make these systems as complicated as you want, but at the end of the day, the owner wants something that works, functions and is maintainable." — Dale Garfield 🗓️ Your Green Building Action Plan Transform your next project with these steps: This Week: Ask what sustainability and energy performance actually mean to the owner before recommending another technology. Start with their priorities, operating realities, and long-term goals. This Quarter: Review an upcoming project for opportunities to improve mechanical efficiency without unnecessary complexity. Look at proven strategies such as heat pumps, heat recovery, variable frequency drives, high-efficiency equipment, and practical controls. This Year: Start designing for what the building may need next—not just what gets installed today. Explore solar-ready structural and electrical infrastructure and other strategies that can create a pathway toward lower-energy or net-zero-capable buildings. 🔗 Connect & Learn More 🌿 Access full episode resources: https://www.gbes.com/podcast 🎙️ **Read the transcript: here** 🔗 Connect with Dale Garfield: 🏢 Explore EUA: [https://eua.com/,](https://eua.com/) https://eua.com/eua-people/dale-garfield/ 🌎 LinkedIn: https://www.linkedin.com/in/dale-garfield/ 💚 Join the Green Building Movement: https://www.greenbuilding.news/subscribe 💚 Want More Green Building Insights?

🌎 The Green Impact Report Quick take: What happens when AI adoption runs headfirst into energy constraints? Josh Rainbow sees technology, infrastructure, power, and sustainability becoming increasingly interconnected — and believes the winners will be the people who can turn emerging technology into measurable business outcomes. From running an AI-native company with roughly 250 AI agents to bringing global leaders together through Future Summit, Josh offers a fascinating look at where technology, energy, investment, and sustainability are heading next. 🫡 Meet Your Fellow Sustainability Champion Josh Rainbow is an entrepreneur, technology leader, investor, and founder of Future Summit, an international platform focused on bringing leaders together to accelerate trade, technology adoption, investment, and meaningful business relationships. Born and raised in Edmonton, Alberta, Josh moved to Calgary in his late teens and studied quantitative sciences at the University of Calgary, building a foundation in advanced mathematics, statistics, economics, and computer science before moving into technology. Today, his work spans events and media, AI advisory, venture investing, and global business development. Through Future Summit, Josh and his team work across technology, energy, data centers, infrastructure, finance, and other emerging sectors. His company has also embraced an AI-native operating model, using roughly 250 AI agents across functions including financial reporting, operations, project management, administration, marketing, sales, and research. 🌱Breaking Ground on Better Building In this episode, Josh Rainbow connects AI, energy, infrastructure, and sustainability — and challenges leaders to think about technology through the lens of real business outcomes: 📚 Key Insight #1: AI can make a business leaner — but automation needs to solve real business problems. The Challenge: Companies can become fascinated with emerging technology without connecting it to revenue, cost reduction, scalability, or another measurable business outcome. Josh learned that traditional businesses don't necessarily care how impressive a technology is — they care what it does for the business. The Solution: Josh's company has become AI-native, deploying roughly 250 AI agents across financial reporting, operations, administration, project management, marketing, sales, funnel research, and other functions. His philosophy is to apply technology directly to business problems rather than adopt it simply because it's new. ROI: Josh says these initiatives helped reduce his company's operating expenses by approximately 4 –50% year over year, allowing that capital to go back into the business while supporting both sustainability and scalability. 🫶 Key Insight #2: The AI revolution is quickly becoming an energy and infrastructure challenge. The Challenge: The next wave of AI requires enormous amounts of compute — and that compute requires reliable power. Josh argues that access to energy is becoming one of the major constraints facing data center and AI expansion. The Solution: Josh is closely watching technologies such as small modular nuclear reactors as potential tools for increasing future energy supply. While he acknowledges that SMRs remain expensive and highly regulated today, he sees the underlying need for abundant energy as critical to supporting continued technology growth. ROI: More reliable and abundant power could help unlock additional data center capacity and AI infrastructure. For businesses, Josh sees energy availability and financing becoming increasingly important factors in determining where and how quickly new compute infrastructure can scale. 💡 Key Insight #3: Technology only matters when it creates measurable business value. The Challenge: Technology conversations often start with the tool: Look at this incredible technology. But established companies aren't necessarily interested in innovation for innovation's sake. The Solution: Start with the business objective. Josh combines his background in technology with experience in sales and business strategy to understand how an organization makes money first — and then determine where technology can solve a meaningful problem. ROI: Connecting technology investment directly to revenue, operating costs, productivity, scalability, or another business objective gives executives a much clearer reason to invest. For sustainability professionals, the same mindset creates a stronger bridge between innovation and the business case needed to get projects approved. 🎧 Sustainable Soundbite Options "I believe in paying it forward because that's how I've gotten to this point." — Josh Rainbow 🧗 Your Green Building Action Plan Transform your next project with these steps: This Week: Pick one repetitive task inside your sustainability, engineering, or operations workflow and ask whether AI could reduce the manual work. Start with the business problem — not the AI tool. This Quarter: Quantify the outcome. Track whether your technology initiatives are actually reducing operating expenses, increasing productivity, generating revenue, or creating another measurable benefit. This Year: Look beyond individual building technologies and evaluate the bigger infrastructure picture. Consider how energy availability, data centers, AI, automation, and emerging power technologies could affect your organization's long-term sustainability and technology strategy.
