The European regulation is reshaping design constraints much faster than aesthetic trends. Two major texts, the revised EPBD directive and the new Construction Products Regulation, require agencies and design offices to recalibrate their methods from the sketch phase. The innovations in architecture and construction for the coming months are first reflected in these regulatory frameworks, before translating into material choices or volumetrics.
Embodied carbon and the EPBD directive: the real regulatory change in construction
The revised EPBD directive (Directive EU 2024/1275) mandates the declaration of global warming potential over the life cycle starting in 2028 for new buildings over 1,000 m², and then for all new buildings from 2030. This timeline shifts the focus: energy performance in operation is no longer sufficient; it is the embodied carbon in materials, transport, and implementation that falls within the regulatory scope.
For architects, this means integrating a life cycle assessment (LCA) from the initial sketches, not at the end of the DCE. The choice between a concrete, wood, or mixed structure is no longer solely based on structural capacity or budget: it determines the project’s compliance.
We observe that public project owners are beginning to include carbon thresholds in their programs, anticipating the obligations of 2030. Agencies that do not yet have LCA tools integrated into their BIM workflow are accumulating operational delays that are difficult to catch up on in a few months. To follow the news on Archi Line, this has been a recurring topic for several quarters, indicating that the wood sector is actively preparing for it.
Digital product passport: what the new construction products regulation changes
The Construction Products Regulation (EU) 2024/3110 is applicable from January 8, 2026. Its most structural contribution to architectural design is the introduction of a digital product passport. Each material placed on the European market must be accompanied by a standardized, machine-readable data set covering its environmental and technical characteristics.
This is not just an administrative change. In practice, material data becomes a regulatory object, not just a PDF commercial sheet. An architect prescribing a bio-sourced insulation or low-carbon concrete can rely on comparable, verifiable data that can be contested in case of disputes.
Direct consequences on prescription
The prescription in CCTP will evolve. The “or equivalent” clauses must be based on measurable criteria from the digital passport, not on declared performances from catalogs. We recommend that agencies review their material libraries now to identify products for which manufacturers do not yet provide data compliant with the new framework.
- French FDES sheets must align with the European format of the product passport, which requires updates from manufacturers
- CCTP drafting software integrating the INIES database will need to adapt their connectors to utilize data from the digital passport
- Project managers working in 5D BIM (costs) or 6D BIM (life cycle) gain an immediate advantage, as the passport directly feeds these dimensions
Carbon reporting in construction: selective thresholds and impact on renovation projects
Carbon reporting requirements are becoming more selective based on the size and purpose of the building. This regulatory granularity creates asymmetry: a renovation project for collective housing in the city center is not subject to the same constraints as a new tertiary facility on the outskirts. Architects must identify early on which regulatory regime their project falls under.
For renovation, a sector that represents the majority of the volume of work in France, the embodied carbon of replacement materials (joinery, insulation, coatings) is gradually being included in calculations. An energy renovation project that replaces PVC windows with aluminum with thermal break significantly alters the overall carbon balance, even if the thermal performance achieved is identical.
Technical arbitration between energy performance and material footprint
The arbitration is no longer binary. We find that some renovation projects achieve better overall performance (energy + carbon) by retaining existing structural elements rather than demolishing to rebuild to current standards. Structural reuse becomes a lever for compliance, not just an ethical choice.
Digital twins and risk management: beyond classic BIM
The digital twin goes beyond the design BIM model. Recent applications concern risk management during the operational phase, particularly for buildings located in exposed areas (flooding, shrink-swell of clays, moderate seismicity). The digital twin allows for simulating the building’s behavior against updated climate scenarios, not just against historical data used during the initial design.
For new projects in urban areas, this technology alters the design of foundations and envelopes. An architect designing a collective housing building in a municipality affected by shrink-swell of clays can adjust the thermal inertia of walls, the depth of foundations, and peripheral drainage based on 30-year climate projections integrated into the digital model.
- The digital twin feeds building permit applications in risk areas by providing contestable simulations
- Insurers are beginning to integrate this data into the assessment of ten-year risks
- Local authorities use urban digital twins to arbitrate between densification and climate resilience
Bio-sourced materials and low-carbon concrete: where the sector stands
Low-carbon concrete and bio-sourced materials (CLT wood, hemp, compressed straw) are no longer niche solutions. The sector is structuring around stabilized implementation standards, which removes the main barrier to prescription in public markets. Feedback from construction sites on buildings delivered over the past three years shows thermal performances that comply with simulations, even in continental climates.
The point of caution remains supply. Lead times for large-section CLT wood remain long, and the availability of low-carbon concrete varies by regional plants. A sustainable construction project must integrate these logistical constraints into the preliminary schedule, or risk delaying delivery.
Architecture and construction in 2026 are defined less by formal choices than by the ability of agencies to integrate these regulatory frameworks into their project processes. European texts set a tight schedule, and the most informed project owners have already translated it into programmatic requirements. Agencies that master LCA, the digital product passport, and the digital twin have a measurable competitive advantage in both public and private tenders.
