Sustainable construction materials: what decision-makers should know
Material choices are increasingly central to how commercial and mixed-use buildings perform over decades. For owners, tenants, and investors, the topic is not only about operational energy; it also includes embodied carbon, maintainability, resilience, and the ability to adapt assets to future requirements.
The importance of this shift is reflected in the scale of the challenge: the buildings and construction sector accounts for a significant share of global emissions, with widely cited figures of around 37% globally when including building operations and construction activities, as referenced via Autodesk’s summary of the sector and its sources.
This article explains how sustainable construction materials fit into long-term real estate strategy, which material categories are most relevant today, and what practical questions decision-makers can ask when evaluating options for new-builds and refurbishments.
What makes a material “sustainable” in commercial real estate?
In practice, sustainability is rarely a single attribute. A material can reduce emissions at manufacture, improve durability, support circularity, or contribute to healthier indoor environments. A useful definition is that sustainable building materials should reduce carbon emissions, use fewer resources, and support longer building life spans.
From an asset perspective, this means looking beyond the product label and considering life-cycle outcomes: sourcing, transport, installation waste, expected replacement cycles, and end-of-life pathways (reuse, recycling, or disposal).
Research also points to measurable benefits across emissions, economic performance, and occupant health when environmentally friendly materials are evaluated across the full life cycle, rather than in isolation.
Key performance lenses for decision-makers
- Embodied carbon: emissions associated with extraction, manufacturing, transport, and construction.
- Service life and maintenance: frequency of repair, refurbishments, and replacements.
- Circularity: potential to reuse, disassemble, or recycle at end of life.
- Supply chain quality: availability, certification, and consistency at project scale.
- Health and comfort: impacts on indoor air quality and occupant wellbeing.
Core categories of sustainable construction materials
Below are material categories most commonly discussed in the market today. Not every option suits every project type or regulatory context, but understanding the trade-offs helps owners and investors ask better questions early in planning.
1) Mass timber and engineered wood products
Mass timber includes products such as cross-laminated timber (CLT) and other engineered wood systems used for structural elements. These products can substitute for more carbon-intensive materials in certain applications, while offering prefabrication advantages that may reduce waste and shorten construction time.
Autodesk notes that mass timber is gaining traction as a lower-carbon alternative to conventional materials and highlights that it can support faster construction with less waste. A referenced study comparing a reinforced concrete building with a hybrid CLT commercial building found an average reduction in global warming potential of 26.5% for the hybrid CLT option (excluding biogenic carbon emissions).
For decision-makers, sourcing is critical. Timber is renewable, but the sustainability case depends on forests being managed to recognized environmental standards (biodiversity, regeneration, and water quality).
2) Salvaged, reclaimed, and recycled materials
Reusing materials is one of the most direct ways to reduce waste and avoid the emissions associated with producing new products. Autodesk highlights salvaged materials such as reclaimed wood, recycled steel, bricks, and glass as practical examples that give materials a second life and help keep waste out of landfills.
Recycled steel is frequently cited as a high-impact lever because steel is widely recyclable. SFS summarizes that using recycled steel can reduce energy use substantially compared with producing new steel, referencing data that indicates energy savings of 60–74% depending on the recycling pathway and product category.
For commercial assets, reclaimed materials can also support tenant expectations around ESG narratives, but they require disciplined quality assurance. Specifications, structural performance, fire ratings, and traceability must be verified, particularly in regulated occupancies.
3) Lower-impact concrete strategies (including precast and newer mixes)
Concrete is often unavoidable in commercial construction, but there are approaches that can improve its footprint and performance. Autodesk describes precast concrete as an offsite method that can reduce waste through repeatable molds, controlled curing, and manufacturing to exact dimensions.
Autodesk also discusses engineered cementitious composites (often referred to as “bendable concrete” or ECC), noting its crack resistance and durability advantages. From a long-term ownership lens, durability matters because fewer repairs can mean reduced material use, lower disruption for tenants, and potentially a lower whole-life carbon impact.
Not all innovative concrete approaches are equally mature. For large-scale, long-horizon assets, decision-makers typically prioritize solutions with proven performance data, supply chain depth, and clear certification pathways.
4) Bio-based materials such as bamboo and mycelium (selected applications)
Bio-based materials are often discussed for their renewability and potential end-of-life benefits. Autodesk describes bamboo as a flexible, renewable resource that can be used structurally and decoratively, with low waste because the whole stem can be used and leftover pieces are compostable.
However, decision-makers should also weigh durability requirements, weathering, and processing intensity. Accoya’s overview of bamboo notes that while bamboo can be strong and fast-growing, raw bamboo is not naturally weather resistant and may require intensive processing (including treatments and bonding) to perform in certain outdoor applications.
Mycelium is another bio-based option discussed by Autodesk. It is described as organic and compostable, and it can be molded into building components when combined with timber, sawdust, or demolition waste. Today it is not yet used at massive scale, so it is more often considered for targeted, non-structural, or experimental applications rather than core building structure.
Practical implications for investors, occupiers, and asset managers
Material choices affect more than compliance. They influence operating risk, leasing competitiveness, and long-term capex planning. The following implications tend to matter most for business owners, investors, and corporate tenants.
Whole-life cost and maintenance planning
Some sustainable construction materials can have higher upfront costs, while offering advantages in longevity, reduced maintenance, or improved resilience. Autodesk highlights cost and predictability barriers for certain newer methods, noting that the industry still faces challenges such as higher upfront cost and limited standardization for some solutions.
From a portfolio viewpoint, the decision is best framed as a whole-life assessment: expected refurbishment cycles, tenant fit-out churn, and the “cost of disruption” during repairs can be as important as the initial material price.
Embodied carbon measurement and reporting
Embodied carbon is increasingly relevant in project governance and reporting. The University of the Built Environment notes that embodied carbon is a meaningful component of global energy-related emissions, and Autodesk emphasizes that measuring embodied carbon remains challenging but important in early project phases.
For decision-makers, the practical takeaway is that embodied carbon should be addressed early enough to influence design, not merely documented after key specifications are locked.
Certifications and market expectations
SFS points to the role of green building certifications such as LEED and BREEAM in shaping how sustainability is assessed and communicated. For commercial landlords and investors, certification is not inherently the objective, but it can provide a structured framework for documenting performance, managing risk, and aligning with occupier requirements.
Materials contribute to these outcomes through responsible sourcing, low-emitting product selections, waste reduction strategies, and circular-economy considerations.
A long-term perspective: sustainability as durability, adaptability, and circularity
For a long-term-oriented owner and developer, sustainability is inseparable from durability and adaptability. A building that lasts longer, needs fewer disruptive interventions, and can accommodate changing tenant needs can reduce resource use over time.
Trends highlighted by SFS include increased adoption of circular economy principles, such as designing for disassembly and keeping materials in use longer. This is particularly relevant in commercial and mixed-use properties where refurbishments are frequent and fit-outs evolve.
At the same time, the market is still working through barriers: limited standardization for newer materials, varying levels of technical maturity, and the need for reliable supply chains. A pragmatic strategy is to prioritize proven solutions first (recycled content, prefabrication, responsibly sourced timber, lower-waste construction methods) while selectively piloting emerging materials where performance requirements allow.
Conclusion
Sustainable construction materials are best understood as part of a long-term asset strategy, not a standalone specification choice. For commercial and mixed-use real estate, the most relevant benefits typically relate to embodied carbon reduction, improved durability, circularity, and alignment with evolving reporting and certification expectations.
Mass timber and engineered wood, salvaged and recycled materials, lower-impact concrete approaches, and selected bio-based materials each offer distinct advantages and trade-offs. The strongest outcomes come from evaluating materials across the full life cycle, verifying quality and sourcing, and making decisions early enough that sustainability targets can shape design and procurement.
