Choosing the right green materials for your project isn’t just about ticking boxes for sustainability certifications—it’s about future-proofing your investment. Using green materials creates spaces that reduce harm to the environment and offer healthier, more productive spaces for your tenants.

Defining green building materials

Green building materials refer to any material with a lower environmental impact when produced, installed, and maintained than its traditional counterpart. This takes into account the full lifecycle of the material to ensure an overall improvement in sustainability. The U.S. Green Building Council calls these materials environmentally preferable products for their Leadership in Energy and Environmental Design (LEED) program and as part of their ESG Green Buildings criteria.

What makes them sustainable?

The sustainability of building materials is measured by their environmental footprint. It includes factors such as energy efficiency in production, the renewability of resources, and end-of-life recyclability. What makes each green building material sustainable depends on the specifics of the material. Some offer significantly more durability which reduces the environmental costs of maintenance while others reduce the environmental footprint of production.

LEED’s environmentally preferable products give us a few key criteria to help evaluate the sustainability of green building materials. These criteria include:

  • Local production: Prioritizing materials that are extracted and manufactured within a certain distance of the project site minimizes transportation emissions and bolsters the local economy.
  • Reclaimed material: Incorporating the use of materials with reclaimed, salvaged, or refurbished content extends the lifecycle of existing resources reducing waste.
  • Recycled content: Selecting products that contain a defined proportion of post-consumer or pre-consumer recycled content supports the market for recyclables and lessens the demand for virgin materials.
  • Certified wood: Choosing wood-based materials that are certified by recognized standards like the Forest Stewardship Council ensures that wood products come from responsibly managed forests.
  • Bio-based materials: Utilizing bio-based materials derived from renewable plant and animal sources makes products more compostable and reduces emissions for production.
  • Extended producer responsibility: Beyond the product itself, producers can also make a product more sustainable by offering take-back programs and other end-of-life waste management strategies.

The role of green construction in fulfilling ESG criteria for businesses

Embracing green construction practices is a strategic move for businesses aiming to excel in their Environmental, Social, and Governance (ESG) performance. Here’s how green construction can help businesses fulfill every aspect of ESG:

  • Environmental: Green construction reduces a business’s carbon footprint through energy-efficient designs and sustainable materials, directly supporting environmental conservation efforts.
  • Social: By minimizing waste and enhancing indoor environments, green construction promotes community well-being and reflects social responsibility.
  • Governance: Proactively adopting green construction prepares businesses for evolving environmental regulations such as the EU’s CSRD, demonstrating foresight and strong governance to stakeholders.

11 best green building materials to count on: Now and in the future

Innovative green building materials are transforming the construction industry. Here are eleven materials paving the way for a sustainable future:

  • Engineered cementitious composite (ECC): Also known as bendable concrete, ECC offers 500 times greater resistance to cracking and superior shock absorption compared to traditional concrete. With the inclusion of small polymer fibers, ECC can be produced more sustainably and infused with CO2 to further reduce its carbon footprint.
  • Mass timber: This collective term includes various mechanically bonded softwoods like CLT, LSL, LVL, NLT, and GLT. As a viable alternative to steel and concrete, mass timber reduces the potential contribution to global warming by 26.5% compared to traditional concrete.
  • Salvaged materials: Reusing materials diverts them from landfills and gives them new life. In recent years, this has even become a trending design choice.
  • Bamboo: Known for its rapid growth and impressive tensile strength, bamboo is a renewable resource that doesn’t require replanting post-harvest. Its versatility allows for structural and decorative use, although it requires treatment against insects and rot.
  • Mycelium: Fungi-based materials using mycelium bring an organic and compostable component to a building material. It also resists mold, water, and fire making it an effective additive when making bricks.
  • Precast concrete: Manufactured offsite for increased efficiency and waste reduction, precast concrete allows for more precise and controlled construction.
  • 3D printed concrete: With the ability to print components on or near construction sites, 3D printed concrete minimizes transportation costs and simplifies supply chains.
  • Straw bale: Excellent for insulation and soundproofing, straw bale construction can significantly cut temperature control costs and offers a sustainable alternative to traditional insulators.
  • Recycled plastic: Polymeric timbers combine recycled and virgin plastics to create a hybrid plastic of equal strength while taking materials out of landfills.
  • Ferrock: A newer material made from steel dust and ferrous rock, Ferrock offers a concrete alternative that is stronger and captures CO2 through a process called carbonation.
  • Terrazzo: With its long lifespan and low maintenance, Terrazzo flooring combines recycled materials like glass or marble in a polished concrete or epoxy base for a durable and decorative finish.
