Let’s face it: the days of designing a building like it’s a giant energy-guzzling fortress are long gone. Today’s architects, designers, and engineers have a new mantra: sustainability. Green building practices are no longer niche—they’re essential. And what makes a building green, you ask? It’s all about the materials.
Here’s the scoop: we’re diving into eight manufacturable, sustainable products that any commercial architect, designer, or engineer can specify today. These products align with some of the hottest trends in sustainability and green building practices. Bonus: you’ll look like a hero to both your client and the planet.
Cross-Laminated Timber (CLT)
If wood is the OG of building materials, CLT is its cooler, more eco-friendly cousin. Made from layers of solid-sawn lumber glued together at right angles, CLT is not only strong but also sustainable. It’s a renewable resource that stores carbon instead of emitting it.
Architects love CLT for its versatility and aesthetic appeal. Think warm, natural interiors with structural integrity to boot. Projects like the T3 Building in Minneapolis have proven that timber can rival steel and concrete in commercial construction.
Why Specify It? It’s carbon-negative, lightweight, and beautiful.
Recycled Steel
Steel may not scream “green,” but hear us out. Recycled steel uses up to 75% less energy to produce compared to virgin steel. Plus, it’s infinitely recyclable. Your steel beams today could be someone’s skyscraper tomorrow.
Recycled steel is perfect for structural components in commercial buildings. It’s strong, durable, and—thanks to modern fabrication techniques—can be shaped into just about any design you can dream up.
Why Specify It? It’s durable, endlessly recyclable, and reduces mining impact.
Green Concrete (Geopolymer Concrete)
Concrete has a dirty secret: it’s a carbon monster. Enter green concrete, which replaces traditional Portland cement with materials like fly ash or slag. This reduces carbon emissions by up to 80%. Some versions even use recycled aggregates, making it doubly green.
Green concrete is ideal for commercial projects that require durability without the guilt. The One Angel Square building in Manchester, UK, is a shining example of how sustainable concrete can deliver on both performance and aesthetics.
Why Specify It? Lower carbon footprint and the same durability as traditional concrete.
Bamboo Flooring and Panels
Bamboo isn’t just for pandas anymore. This fast-growing grass (yes, it’s a grass!) is a renewable resource that regenerates in just a few years. Its strength rivals hardwoods, and it’s a versatile material for flooring, paneling, and even structural components.
Architects love bamboo for its modern, clean look and sustainability credentials. It’s perfect for interiors that need a natural touch. Check out the Shanghai Tower, which incorporates bamboo into its design.
Why Specify It? It’s fast-growing, renewable, and stylish.
Low-Flow Fixtures
Okay, so low-flow fixtures aren’t technically a building material, but they’re a game-changer for green building design. These products—including toilets, faucets, and showerheads—use significantly less water without sacrificing performance.
For example, the Kohler Highline Arc toilet saves up to 16,500 gallons of water per year per unit. Now multiply that across a commercial office building, and you’re saving enough water to fill an Olympic-sized swimming pool.
Why Specify It? Massive water savings with no compromise on functionality.
Photovoltaic Glass
Imagine windows that double as solar panels. That’s photovoltaic glass in a nutshell. These transparent solar panels capture sunlight and convert it into energy, turning skyscrapers into vertical power plants.
The Net Zero Energy Building in Singapore uses photovoltaic glass to generate electricity while maintaining natural light inside. It’s a win-win for energy efficiency and aesthetics.
Why Specify It? Generate renewable energy without sacrificing design.
Insulated Concrete Forms (ICFs)
ICFs are like the Swiss Army knife of sustainable construction. These blocks or panels are made from expanded polystyrene and serve as both formwork and insulation. Once filled with concrete, they create energy-efficient walls with incredible thermal performance.
ICFs are perfect for commercial projects that need to balance strength and energy efficiency. They’re easy to install and reduce heating and cooling loads significantly.
Why Specify It? High energy efficiency and excellent thermal performance.
Rammed Earth Panels
If you think dirt can’t be luxurious, think again. Rammed earth is an ancient construction technique that’s making a comeback. Modern rammed earth panels are manufactured for easy installation and offer a stunning natural aesthetic.
Rammed earth is ideal for commercial interiors and façades, providing thermal mass, sound insulation, and a unique visual appeal. It’s like bringing a slice of the earth indoors—literally.
Why Specify It? Sustainable, thermally efficient, and visually striking.
Key Trends These Products Address

Why It Matters
Sustainable and green building materials aren’t just trendy—they’re necessary. As architects, designers, and engineers, we have the power to make choices that shape not just buildings but the future of our planet. Specifying these eight products doesn’t just tick boxes on a LEED checklist; it’s a step toward a more sustainable world. So, the next time you’re poring over specs, remember: your choices matter. And with options like these, you’re not just building structures—you’re building a legacy.
