The Next Material: Mycelium, Aerogel and the Innovations Worth Watching

Define Future Building Materials

The term “future building materials” refers to innovative construction substances that are currently under serious research and development or in the early stages of commercial deployment. These materials stand out for their potential to significantly enhance sustainability and performance in the built environment. As the construction sector is a major contributor to global energy consumption and CO2 emissions, the push toward lower-carbon, more sustainable materials is critical. Current trends emphasize reducing embodied carbon, improving energy efficiency, and integrating renewable or bio-based components. For example, some recently introduced materials are already making waves by combining environmental benefits with functional improvements, setting the stage for widespread adoption.

Criteria for “Worth Watching”

To determine which materials deserve attention, we apply several key criteria. First, sustainability is paramount — materials must demonstrate reduced environmental impact, such as low embodied carbon or biodegradability. Performance metrics like thermal insulation, durability, and fire resistance are also crucial. Additionally, commercial readiness plays a vital role; materials should be approaching or already in early market deployment, ideally within a five-year adoption horizon to ensure relevance. Industry standards and certifications, such as Environmental Product Declarations (EPDs), help validate these claims and guide credible material selection frameworks, ensuring that the materials are not only innovative but also practical and compliant.

Mycelium and Bio-based Materials

Mycelium, the root structure of fungi, is gaining recognition as a promising bio-based material for construction. It can be grown into specific shapes and used as insulation, packaging, and even structural components. Mycelium insulation, in particular, offers benefits such as low embodied energy, biodegradability, and competitive thermal performance. A peer-reviewed study highlights these strengths but also notes challenges like durability and scalability that must be addressed for broader adoption.

Other bio-based materials, such as hempcrete and straw panels, are also gaining traction due to their renewable nature and carbon sequestration abilities. However, a common pitfall in using bio-based materials is underestimating their moisture sensitivity, which can impact longevity and performance. To avoid this, designers should ensure proper detailing and ventilation strategies when specifying these materials.

For instance, a case study involving mycelium insulation demonstrated effective thermal regulation in a small-scale building prototype, showcasing its potential in real-world applications.

Aerogel and High-Performance Insulation

Aerogel is a cutting-edge insulation material known for its exceptionally low thermal conductivity, outperforming traditional insulation options like fiberglass or foam. Its unique porous structure traps air, providing superior thermal resistance in a thin profile. Aerogel’s application in commercial buildings ranges from insulating windows to wall panels, where space constraints demand high-performance insulation without bulk.

Compared to traditional materials, aerogel offers advantages in energy savings and durability, although cost and handling challenges remain barriers to widespread use. According to research from SINTEF, aerogel’s high-performance insulation characteristics make it a material worth watching as manufacturing advances may reduce costs.

Concrete and Cement Innovations

Concrete and cement are foundational to construction but are also significant sources of CO2 emissions. Next-generation concrete solutions focus on reducing environmental impact through low-carbon materials, alternative binders, and improved production methods. Innovations include incorporating industrial by-products, using carbon capture technologies, and developing cements with reduced clinker content.

Several projects are already employing these advanced concretes, demonstrating comparable or enhanced performance while lowering carbon footprints. The International Energy Agency outlines pathways for scaling these materials, emphasizing the importance of standards, demand signals, and public procurement in accelerating adoption.

A key decision rule for developers is: if a project targets green certification or carbon reduction goals, prioritize next-generation concrete with verified low embodied carbon; if not, traditional concrete may still be appropriate but consider emerging options to future-proof the building.

Commercial Readiness and Certification

For innovative materials to move beyond the lab and into construction sites, achieving commercial readiness and certification is essential. This process involves rigorous testing, engineering review, and compliance with building codes. The ICC-ES provides product evaluations that help verify safety, performance, and code compliance, facilitating market acceptance.

Materials recently certified through such processes gain a competitive edge by assuring architects, developers, and regulators of their reliability. A common pitfall is rushing to market without adequate certification, which can lead to project delays or failures. To avoid this, stakeholders should verify certification status early in the specification process.

Five-Year Adoption Horizon

Looking ahead, many of these materials are poised for meaningful adoption within the next five years. Factors influencing this timeline include technological maturation, cost reductions, regulatory support, and market demand. Industry experts predict that low-carbon cement and concrete pathways, alongside bio-based insulation and aerogel, will see accelerated deployment as sustainability regulations tighten and clients prioritize green buildings.

However, adoption speed can be slowed by supply chain constraints or lack of familiarity among specifiers. To overcome these barriers, ongoing education and demonstration projects play a critical role in building confidence.
