Energy performance, construction products and environmental requirements affect design, procurement and the value of completed buildings. We help translate regulatory requirements and sustainability promises into practical project obligations.
Distinguish EU objectives from national project duties
The recast Energy Performance of Buildings Directive sets an EU framework whose implementation depends on national measures. Its general transposition deadline was 29 May 2026. For an individual German project, verify the national rules actually applicable at the relevant time instead of treating every directive provision as an immediate private obligation.
Existing buildings, new construction, major renovation and different uses can trigger different requirements. Coordinate energy advice with planning, heritage, fire protection and the owner’s intended operation.
Specify performance and documentation
Define the promised energy standard, testing method, data, commissioning records and responsibility for certification. If a particular sustainability rating is part of the brief, state who must deliver which evidence and how changes affect the target.
The new EU Construction Products Regulation has applied in substantial part since January 2026, with transitional arrangements. Product-specific requirements must be checked; a universal immediate digital product passport obligation should not be assumed.
Manage retrofit and circular-construction risk
Existing conditions, hazardous materials, reuse and compatibility can create unexpected costs. Allocate investigation duties, change procedures, waste responsibilities and product evidence before work begins. Green marketing statements should match the actual contractual promise and supporting records.
Four practical examples
Illustrative scenarios: the appropriate steps depend on the contract, evidence and applicable law. These are not reports of client matters.
An office retrofit
The owner plans façade and heating upgrades. Identify the applicable national requirements and coordinate the design and contractual performance target.
Reused structural elements
A contractor proposes reclaimed components. Check suitability, documentation and the agreed responsibility for testing.
A certification shortfall
The completed building misses the targeted rating. Trace the promised obligation, assessment method and cause before allocating liability.
A substituted product
A specified product becomes unavailable. Review the alternative’s evidence and compatibility before approving substitution.
Documents that help us assess your position
Energy assessments, design specifications, product documentation, certification requirements, existing-building surveys and the proposed allocation of responsibilities.
Discuss your project or dispute
Tell us where the project is located, who is involved and whether a deadline is approaching. We can then clarify the scope of the proposed engagement and the next steps.
