Deep Green

Brought to you by Metropolis, Deep Green is a podcast about how the built environment impacts climate change and equity. Buildings are some of the biggest things we make as human beings. We explore how through understanding buildings, cities, and all the things that go into them, we can do better for the environment and all life on this planet.

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. Befor...

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 ...

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.

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 carb...

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 fle...

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 bu...

What makes one product more sustainable than another? It’s a question that anyone concerned with their impact on the planet must confront. How do we choose the right couch, coffee machine, flooring, tiles, or curtain wall system—so that we’re doing the most good for both people and the environment?

That’s the question Lisa Gralnek has been working to answer.

Gralnek is the U.S. Managing Director and Global Head of Sustainabi...

If there’s one defining trend in American architecture over the last decade, it’s the rediscovery of wood as a construction material. Mass timber buildings—made from large wooden panels, columns, and beams—are rising across North America, with developers racing to construct the tallest wooden tower. A new contender, the 32-story Edison in Milwaukee, just broke ground and is set to claim the title of the tallest mass timber...

Buildings account for 40 percent of the world’s carbon emissions. If you’re an architect, or a frequent listener to this podcast, you already know that.

“Buildings offer some of the most cost-efficient ways of reducing carbon emissions and comb...

What is Office Furniture’s Role When it Comes to Climate Impact? In 2018, Americans threw out 12.1 million tons of furniture—and nearly 80 percent of that ended up in landfills. And the problem may not be where you think it is. Fast-furniture folks get a bad rap, right? It turns out that's not the biggest problem with furniture. Eight million or so of that 12.1 million tons of waste furniture was office furniture. There’s ...

The furniture industry has seen something of a transformation over the last decade with the rise of fast furniture: cheap, disposable pieces, often produced overseas with little to no oversight. Every year in the United States, about 12 million tons of furniture goes to waste, and 80 percent of that ends up in our landfills. In addition to contributing, through that enormous amount of waste, to our environmental problems, ...
