    Making the Case for Slate

    Here at Deep Green, we often shine a spotlight on traditional building materials that have fallen out of favor for a variety of reasons—but that we believe deserve reconsideration by today’s architects and designers, especially those concerned about the environmental and social impacts of their projects. Slate—a gray, flaky signifier of 19th-century luxury—for example, is one that we think deserves a second look. Before the 1930s, when asphalt composite shingles became the most common roofing material in North America, the middle class was rushing to build Victorian-style homes or renovate their Georgian and Colonial-style mansions with slate roofs. And there was a reason. Slate was easy to maintain, elegant in color, and excellent in thermal performance. Many beautiful buildings around the world still prove its durability, with roofs that have lasted hundreds of years. No wonder there was a slate boom in the 19th century—not only in North America but in many other parts of the world where slate roofs have been constructed for thousands of years. In this episode of Deep Green, created in partnership with CUPACLAD, host Avi Rajagopal sits down with Drew Ford, USA regional sales manager for CUPACLAD, one of the world’s leading slate providers. Listen in to learn what makes slate a great choice today and what new possibilities have opened up for this ancient material.

  2. Rediscovering Tile for Sustainable Design

    Rediscovering Tile for Sustainable Design

    Tiles are among the most enduring building materials. Glazed brick tiles have been discovered in archaeological sites and in ancient and medieval buildings around the world. The first glazed porcelain tiles, which date back to 15th-century China, are still around today. And yet, when one thinks of sustainable building products, tile might not be the first to come to mind. More often than not, today’s building industry—with its culture of constructing and demolishing—fails to take advantage of tile’s inherent sustainability. In today’s context, we require that building materials have the lowest possible carbon footprint and be easily reused or recycled. So, how can tile—with its thousands of years of history—fit into today’s frameworks? And how can we build better with this time-tested material in North America? In this episode of Deep Green, created in partnership with AHF and Crossville, host Avi Rajagopal sits down with Noah Chitty, Vice President of Sustainability and Technical Services for AHF and Crossville. Part of the AHF family of brands, Crossville has made great strides in optimizing tile manufacturing by innovating with new technologies and providing transparent information to the design community—efforts Chitty has helped drive. Listen to the episode to learn how this ancient material is being reimagined for a more sustainable future.

  3. Fractals: Nature's Healing Patterns in Design

    Fractals: Nature's Healing Patterns in Design

    In the 1960s, mathematician Benoît Mandelbrot began exploring a concept he initially called self-similarity—geometric forms whose parts resemble the whole. A simple example is a straight line: any segment of it is also a straight line. But this kind of geometry also appears in nature, like in the head of Romanesco broccoli. Each floret forms a spiral that mirrors the spiral arrangement of the florets on the entire head. In 1975, Mandelbrot named this phenomenon a fractal. It turns out fractals are everywhere in nature: the way rivers branch into tributaries, or how a tree trunk grows branches, which then grow twigs. More recently, researchers have suggested that human brains recognize these fractal patterns—sometimes subconsciously—and because we associate them with nature, seeing fractals can evoke similar calming effects as being in a natural environment. So, why discuss fractals on a podcast about sustainable architecture and design? Because fractals are common in pre-modern architecture—found in the ornaments of Gothic cathedrals and the niches of medieval mosques—and today, many designers apply fractal principles to objects and materials, creating products that evoke the same sense of well-being as natural environments. In this episode of Deep Green, created in partnership with Momentum and recorded live from NeoCon 2025, host Avi Rajagopal sits down with Dr. Richard Taylor, whose research underpins our understanding of fractal patterns’ impact, and Anastasija and Martin Lesjak of 13&9, who apply this research in their designs—including a new wallcovering collection for Momentum called Renaturation.

  4. Furnishing a Better Future

    Furnishing a Better Future

    When we think of all the ways we could be designing better buildings—especially commercial buildings like office towers or education spaces—there’s one lever that people still don’t pay enough attention to: furniture. Some numbers for context—about 8 million tons of office furniture end up in U.S. landfills every year. And for a standard office renovation, furniture and furnishings account for about half of the space’s carbon footprint. So yes, furniture can help prevent harm in the world. It can help us make better buildings. But here’s the exciting part: furniture can also be a tool for doing a whole lot of good. We touch and interact with furniture every day. Well-designed furniture can make a big difference to our health and well-being. It also takes skill and craft to produce, which means furniture can uplift and empower communities and involve them in finding solutions for people and the planet. In this episode of Deep Green, created in partnership with Allsteel and recorded live from NeoCon 2025, host Avi Rajagopal sits down with two guests who’ve been helping organizations make real impact through their furniture and architectural product selections: Lisa Brunie-McDermott, Director of Corporate Social Responsibility at HNI Corp., and Madison Gentry, Architectural Product Sales Enablement Manager at Allsteel. Listen in as they discuss how using healthy, beautiful materials in furniture and furnishings can have a multiplier effect on our buildings.

  5. PVC Perspectives: The Path Forward

    PVC Perspectives: The Path Forward

    Polyvinyl chloride—better known as PVC or vinyl—is one of the most ubiquitous plastics in our lives. You’ll find it everywhere: pipes, siding, wiring, flooring, upholstery, wall coverings, and even old-school vinyl records. Sixty-one percent of all PVC produced globally is used in buildings and construction. It’s more fire-retardant than any other common plastic, and with the addition of plasticizers, it can be made as flexible as fabric or as rigid as wood. In certain building types—like hospitals, hotels, and schools—PVC products are widely used because they’re durable, easy to maintain, and able to carry patterns and color. But many sustainability experts and design teams are urging the industry to reduce or avoid PVC where possible. When PVC isn’t responsibly manufactured or disposed of, it can expose workers and nearby communities to harmful dioxins. Poorly regulated PVC can also contain other chemicals of concern, such as heavy metals. For these reasons, the International Living Future Institute keeps PVC on its Red List of materials to avoid. So what’s the path forward? Should we focus on making PVC as safe and clean as possible—or invest in finding alternative materials that offer the same performance benefits? In this episode of Deep Green, created with our partner Mannington Commercial, host Avi Rajagopal sits down with three experts offering distinct perspectives: Shane Totten, vice president of sustainability at Mannington Commercial, which produces both certified, transparent PVC flooring and non-PVC resilient flooring options; David Briefel, sustainability director and principal at Gensler, and co-creator of the Gensler Product Sustainability Standards—a set of material requirements for the firm’s projects; and Annzie Barfield, interior design specialist at LaBella Associates, who works on education, healthcare, and senior living spaces where PVC products are often the default for flooring and wall protection. Together, they unpack the complexities—and possibilities—of designing with (or without) PVC. This season of Deep Green is produced in partnership with Mannington Commercial.

    Designing Buildings to Heal, Not Harm

    Buildings account for 40 percent of global carbon emissions. The construction industry generates nearly a third of all waste in our cities and built environments. The buildings we live and work in influence 11 of the 23 social determinants of health—factors that shape our well-being. And the construction sector is also the second most at risk for labor exploitation and modern-day slavery. We get a lot wrong when we make buildings, and we've spent the last three decades trying to fix that. But what if we shifted our focus—not just doing less bad, but doing more good? That’s the promise of regenerative design: the idea that buildings can help nature regenerate, not just minimize damage. In this episode of Deep Green, host Avi Rajagopal sits down with one of the pioneers of regenerative design, Jason McLennan, chief sustainability officer at Perkins&Will. McLennan is the mind behind transformative frameworks like the Living Building Challenge, the WELL Standard, and the Living Product Challenge, as well as the Declare, Just, and Net Zero certifications. His work has earned him prestigious honors including the Buckminster Fuller Prize, the ENR Award of Excellence, and an Ashoka Fellowship. If anyone can help us see the big picture of sustainability in architecture, it’s Jason McLennan. Tune in for a conversation about the future of buildings, design, and how we can create a world where architecture heals rather than harms.
