Valuable, available, and versatile:
Bio-based materials are often framed as “interesting, but not quite ready” for large-scale projects. In practice, the opposite is increasingly true. Many of these materials are viable, commercially available, and already utilized in buildings today. The next gap to bridge is industry adoption.
include full matrices of product types per application.
Our recent research assessed bio-based materials’ Technology Readiness Levels and identified more than 100 types of commercially available bio-based materials and products that can be specified today, from cork flooring to wood wool, with dozens more that are in the early adoption stage in North America. These materials are supported by growing supply chains, evolving standards and codes, and increasing industry visibility. Many can be integrated into standard assemblies with minimal disruption to cost, schedule, permitting, or procurement.
So why are they still underutilized?
The primary barrier is culture, not performance. The building industry remains deeply rooted in material systems shaped by the industrial era, reinforced by risk aversion, fragmented supply chains, and inconsistent code pathways. Even sustainability-focused teams often default to familiar products like fiberglass, foam board, and composite panels because they are well understood, widely available, and embedded in standard specifications.
Design opportunity:
Shifting this pattern doesn’t require overhauling entire projects. For many projects, substitution is a meaningful starting point. Insulation is a clear example–fiberglass batt can often be replaced with wool, hemp, or wood-based alternatives that offer comparable thermal performance while supporting healthier indoor environments. Medium-density fiberboard (MDF) can be swapped for compressed straw board. These replacements are available today and can meet project constraints while improving environmental and human health outcomes, reducing reliance on petrochemicals, and supporting a more regenerative material economy.
There is also a common misconception that bio-based materials are limited to niche applications. On the contrary, they present abundant opportunities for design exploration across structure, enclosure, and interior elements.
Imagine the possibilities when designers expand beyond material substitution towards aesthetic expression, influencing the relationship between material and design. When bio-based materials influence form, detailing, and spatial quality, designers can convey material origins, provide tactility, and promote biophilic benefits. This approach visibly connects buildings to regional economies, ecological systems, and material life cycles, opening the door to a more integrated relationship between material selection, occupant experience, and architectural intent.

Across our portfolio, we’re seeing bio-based materials applied in a range of project types, including cultural and civic spaces, multifamily housing, sports and recreation projects, a laboratory space, and research. Mass timber and other wood products are established bio-based forerunners, and materials like straw, cork, wool, and even mycelium are becoming more commonplace. Additionally, projects featuring bioregional materials like bamboo in Brazil and riparian willow in Denmark resonate with design for local resources. Looking forward, products made from agricultural byproducts are especially relevant to commercial design because they create longer-lived applications for materials that are often treated as waste.
The value of bio-based materials is not tied to a single performance metric. Many offer multi-attribute benefits that align with broader project goals. They can reduce embodied carbon while also improving occupant health, supporting circularity, strengthening connections to place, and inspiring innovative design. For teams looking to explore further, our full research reports include detailed material matrices, case studies, and guidance on where and how these materials can be integrated.
The key takeaway is simple: bio-based materials are not a future technology story. They are a present-day opportunity to broaden material palettes and rethink how buildings engage with biological systems.

Top actions you can take today:
- Start with circular and regional bio-economies
Regionally sourced products can reduce transportation emissions and boost local economies. Start by identifying available materials and untapped opportunities in your area. Look for bio-based options from agricultural byproducts, renewable crops, forestry residues, or regional crafts, which are often overlooked in procurement. Map local supply chains and waste streams to develop an understanding of the larger systems that materials support. Design teams can invest in regional bio-economies by selecting materials that promote regenerative agriculture, local manufacturing, landscape restoration, and circular flows. In California, examples may include straw and other agricultural byproducts or salvaged timber from wildfire recovery.
- Pick 1–2 products to try in this project
Our research provides matrices of available materials that can replace conventional products today. Review these in our Executive Summary. Then, identify bio-based materials suited to your project with minimal disruption. Align with the team to select one or two material or product types to carry into design development, specifications, and procurement. When selecting products, consider overlapping opportunities. Does a candidate product support wellness, aesthetics, project narrative, or reduce carbon impacts? Pilot efforts, especially in low-risk areas like interior finishes, insulation, and furnishings, can boost confidence and deliver carbon, health, and design benefits.
- Raise the bar / dig deeper
Once teams are comfortable with direct substitutions, explore how materials influence the project’s design. Evolve bio-based strategies beyond swapping one product for another. Materials shape expression, spatial experience, detailing, and performance, inviting fresh opportunities to explore these facets of design. To realize this potential, ask better questions: Where does the material come from? How is it sourced? What are its end-of-use outcomes? Does it align with the AIA Materials Pledge goals to support climate, human, ecosystem, and social health alongside the circular economy? Engage suppliers and use emerging fabrication tools to enable creative, informed applications.
- Share findings / advance the effort
Document pilot projects, share case studies, and discuss successes and challenges to reduce “learning curve repetition” and accelerate new material development from niche to industry standard. Share knowledge through storytelling, education, industry events, publications, procurement policies, building code development, and incentives that promote regenerative material systems.

The Enchanted Hills Camp bathhouse in Napa, CA was constructed from salvaged wood from the fire-damaged campground and preserved fire-damaged benches that were carved by a blind woodworker. The project incorporates wood as a critical sensory tool for the camp’s blind and visually impaired visitors, supporting wayfinding, orientation, acoustic zoning, and thermal comfort.
