New standard building materials are not simply the latest products on the market. In construction procurement and specification, the phrase now points to materials that can prove performance, meet code requirements, disclose environmental impacts, and fit real project conditions. For designers, owners, builders, and suppliers, the shift is practical: broad green claims are giving way to test data, fire and moisture performance, Environmental Product Declarations, lower embodied carbon where available, and clear installation requirements. Material decisions now affect approval risk, cost, carbon reporting, schedule certainty, and long-term asset value. For more context on material categories and market updates, see our building materials coverage.
What the phrase means in practice
The term new standard building materials can be misleading if it is read as a formal product category. There is no single universal standard that labels a product as new standard. Instead, the market is moving toward a layered definition. A material becomes standard only when it can satisfy several expectations at once: structural or enclosure performance, safety, environmental documentation, regulatory acceptance, supply reliability, and measurable value over the building life.
This is a clear change from earlier product marketing. A material might once have been promoted mainly as innovative, recycled, lightweight, natural, or energy-saving. Those claims may still be relevant, but they are not enough for serious specifications. Project teams now ask which standard was used, what product category rule supports the data, whether an EPD is product-specific, whether the assembly has been tested, and whether the local authority having jurisdiction will accept the design pathway.
| Older selection habit | New standard expectation | Practical result |
|---|---|---|
| Choose by price and familiar brand | Compare performance, documentation, and lifecycle impact | More early review before procurement |
| Accept broad sustainability claims | Request verified data such as EPDs and test reports | Less reliance on marketing language |
| Treat materials as isolated products | Evaluate products as part of tested assemblies | Better coordination between design and installation |
| Focus mainly on first cost | Consider embodied carbon, durability, replacement, and maintenance | More balanced life-cycle decisions |
The standards landscape behind the change
The shift is being shaped by several overlapping systems rather than one rulebook. Building codes still set the baseline for safety. Consensus standards provide test methods and definitions. Procurement programs are adding carbon and documentation requirements. Research agencies are organizing methods for lifecycle assessment, resilience, and embodied carbon reduction.
- Building codes define minimum acceptance. Model codes such as the International Building Code influence how jurisdictions evaluate structural systems, fire resistance, mass timber, alternative materials, and methods of construction. Local adoption still matters, so a product that is acceptable in one location may need additional review in another.
- Environmental Product Declarations are becoming a common evidence tool. EPDs do not automatically prove that one product is better than another, but they give a standardized format for reporting environmental impacts such as global warming potential. The underlying product category rule and data quality are critical.
- Federal procurement is accelerating low-carbon documentation. The U.S. General Services Administration updated low-embodied-carbon material requirements in April 2025 for categories including concrete, cement, concrete masonry units, asphalt, steel, and glass. These requirements show how carbon data is moving from voluntary reporting into purchasing criteria for selected public projects.
- EPA programs are pushing consistency in carbon reporting. On December 19, 2024, the U.S. Environmental Protection Agency described its C-MORE program and draft technical work around EPD data quality, digital data formats, and product-level greenhouse gas thresholds, with focus areas including asphalt, concrete, glass, steel, and salvaged or reused materials.
- ASTM and other consensus bodies support the measurement layer. ASTM sustainability-related standards cover topics such as sustainability assessment data collection for building products, whole-building lifecycle assessment comparisons, waste management planning, earthen wall systems, and circular product design principles.
The takeaway is that new standard does not mean experimental without guardrails. It means innovation is being asked to prove itself through documentation that can be reviewed by specifiers, code officials, contractors, insurers, and purchasers.
Material categories moving fastest
Concrete and cement alternatives
Concrete remains central to modern construction, which is why low-carbon concrete and cement alternatives receive so much attention. Common strategies include optimizing mix design, replacing a portion of portland cement with supplementary cementitious materials, improving plant efficiency, using carbon mineralization where proven, and comparing mixes by strength class rather than relying on one generic number.
The challenge is that concrete is highly local. Aggregate sources, cement supply, admixtures, curing conditions, delivery distance, and contractor familiarity all affect performance and carbon data. A lower-carbon mix must still meet compressive strength, durability, exposure, finishing, pumping, curing, and schedule requirements. For that reason, the new standard is not simply less cement at any cost. It is the best verified mix that meets the technical needs of the job.
There is also an important caution. In 2026, the International Code Council noted that its low-carbon alternative cement standard initiative, ICC 1155, had been sunset after board review. That does not mean alternative cements disappear from the market. It does show that standardization is still evolving and that project teams should rely on current code pathways, recognized test data, and qualified engineering review rather than assuming every alternative binder has an easy approval route.
Steel, glass, and asphalt with verified carbon data
Steel, flat glass, and asphalt are increasingly discussed alongside concrete because they are high-volume or carbon-intensive materials in many projects. Federal Buy Clean activity has helped make these categories more visible. For buyers, the practical change is documentation. Product-specific Type III EPDs, facility-level data where available, and clear product category rules can influence whether a material qualifies for a specific procurement requirement.
This does not turn every project into a federal procurement project. Private commercial, residential, and industrial work will vary widely. Even so, public programs often influence the broader market. Manufacturers respond to documentation requests, contractors gain experience collecting submittals, and specification writers adapt language for future projects.
Mass timber and engineered bio-based systems
Mass timber, engineered wood, hemp-lime systems, earthen materials, and other bio-based or mineral-based alternatives are part of the same conversation, but they should not be treated as one group. Mass timber may provide structural capacity and prefabrication advantages. Hemp-lime and earthen wall systems are more commonly discussed for insulation, enclosure, moisture buffering, or low-carbon potential rather than as direct replacements for steel or reinforced concrete frames.
For these materials, the code pathway and assembly testing are especially important. Fire resistance, acoustic performance, moisture behavior, pest resistance, seismic design, connection detailing, and construction sequencing can determine whether the material is practical. The material itself may be promising, but the assembly and installation quality decide the building outcome.
Reused, salvaged, and recycled-content products
Reuse and recycled content are also becoming part of the new standard. Salvaged brick, reclaimed timber, recycled steel, recycled aggregates, and reused interior products can reduce demand for virgin materials. Reuse still requires disciplined verification. Teams need to confirm structural grade where relevant, contamination risk, dimensional consistency, warranty implications, fire performance, and availability at the scale the project needs.
The best reuse strategy is usually designed early. If a project waits until late procurement to consider salvaged materials, schedule risk can outweigh the environmental benefit. Early design flexibility, storage planning, and clear acceptance criteria make circular material use more realistic.
How to specify new standard building materials without adding avoidable risk
Better material standards can improve decisions, but they can also add paperwork and confusion if handled poorly. The goal is not to ask every supplier for every possible document. It is to match documentation to the risk and value of the material. See also: Buying Guides.
- Start with required performance. Define structural capacity, fire rating, exposure class, thermal performance, acoustic target, slip resistance, moisture tolerance, or other essential criteria before discussing carbon or recycled content.
- Ask for the right evidence. For environmental claims, request an EPD when relevant and check whether it is product-specific, third-party verified, current, and based on an appropriate product category rule.
- Review code acceptance early. If the product or assembly is unfamiliar, identify the applicable code section, evaluation report, test standard, or alternative-material approval process before bids are locked.
- Coordinate with the contractor and installer. Some lower-carbon or alternative materials require different curing, fastening, storage, tolerances, or sequencing. A good specification should reflect field conditions.
- Compare like with like. Do not compare a structural material to a finish material, or a cradle-to-gate EPD to a lifecycle claim that includes use and end-of-life stages, without explaining the boundary.
- Keep substitutions transparent. If a product is changed during value engineering, require the substitute to meet the same performance and documentation level as the original.
Where claims still need careful reading
New standard building materials can improve construction outcomes, but the language around them is not always precise. Some claims are useful; others need more context. Project teams should avoid treating any single label as a complete answer.
| Claim | What to check | Why it matters |
|---|---|---|
| Low carbon | Declared unit, lifecycle boundary, product category rule, and comparison baseline | A low number may not be comparable across different methods |
| Recycled content | Pre-consumer or post-consumer content, performance impact, and certification method | Recycled content alone does not prove durability or lower lifecycle impact |
| Natural material | Moisture behavior, fire testing, pest resistance, and code pathway | Natural origin does not automatically mean suitable for every assembly |
| High performance | Specific test standard and measured property | The phrase is too vague unless tied to a measurable result |
| Reusable or circular | Connection design, disassembly method, contamination risk, and future market value | Circularity depends on the whole system, not just product intent |
EPDs deserve special care. They are valuable transparency documents, not universal scorecards. A product with an EPD is not automatically superior to one without an EPD, and two EPDs may not be comparable if their rules, data quality, or declared units differ. Still, verified data is increasingly important because it allows better questions to be asked during design and procurement.
What this means for suppliers and project teams
For suppliers, the direction is clear: documentation is becoming part of the product. Technical data sheets, safety information, EPDs, installation guides, test reports, and code evaluation support are no longer optional extras for many professional buyers. A manufacturer that explains the limits of its product honestly may be more credible than one that makes broad sustainability claims without evidence.
For architects and engineers, the new standard requires earlier coordination. Material decisions should be made alongside structural design, enclosure strategy, fire protection, procurement rules, and lifecycle goals. Waiting until submittals arrive can lead to rejected products, redesign, substitutions, or missed carbon targets.
For contractors, the opportunity is practical knowledge. A team that understands local availability, lead times, batching constraints, installer training, and inspection expectations can turn a promising material into a successful installation. The new standard is not won on paper alone.
For owners, the message is to set priorities clearly. A project may aim for lower embodied carbon, healthier materials, resilience, cost control, faster construction, or easier maintenance. These goals can support each other, but they can also conflict. Clear priorities help the project team choose materials that match the building’s real use rather than chasing every trend.
Frequently asked questions
Are new standard building materials the same as green materials?
No. Green performance may be part of the definition, but new standard building materials also need code readiness, tested performance, reliable supply, installation clarity, and documentation. A product can be marketed as green and still be unsuitable for a specific project.
Does an EPD prove that a material is low carbon?
Not by itself. An EPD reports environmental data using defined rules. To decide whether a product is low carbon, the project team must compare it with a relevant benchmark, check the declared unit and lifecycle boundary, and confirm that the EPD is current and appropriate for the product category.
Are low-carbon materials always more expensive?
Not always. Some options cost more because supply is limited, documentation is new, or installation practices differ. Others can be cost-neutral when they use optimized mix designs, local supply, reduced waste, or efficient manufacturing. Cost should be evaluated with availability, schedule, performance risk, and lifecycle value.
Can alternative materials be used if the local code does not mention them directly?
Often, but not automatically. Many codes allow alternative materials or methods when the applicant demonstrates equivalent performance and the building official accepts the evidence. That evidence may include test reports, engineering analysis, evaluation reports, or project-specific approval documents.
What is the safest way to adopt new materials on a project?
Start with limited, well-defined applications where performance requirements are clear and documentation is strong. Confirm code acceptance early, involve installers before procurement, and keep substitution rules strict. This approach allows innovation without turning the project into an uncontrolled experiment.
