DGNB Certificate

1. Assess project eligibility: Determine which DGNB system variant applies to your project — new construction, renovation, buildings in use, interiors, districts, or exterior spaces. Review the relevant DGNB criteria catalogue available on the DGNB website.\n\n2. Engage a DGNB Consultant or Auditor: Appoint a licensed DGNB Consultant early in the planning phase. Consultants guide the project team through documentation requirements and help optimise performance across the six quality areas. Find accredited experts via the DGNB online directory.\n\n3. Register the project: Submit a project registration application to DGNB, including basic project data and the applicable system variant. Pay the registration fee to initiate the formal process.\n\n4. Plan for performance targets: Work with your design and engineering team to set targets across ecological, economic, sociocultural/functional, technical, process, and site quality criteria. Use the DGNB System as a planning and optimisation tool from the earliest design stages.\n\n5. Compile documentation: Gather and prepare all required evidence — calculations, plans, specifications, energy models, material declarations, and process records — aligned with the DGNB criteria catalogue for your variant.\n\n6. Submit documentation for audit: The DGNB Auditor reviews the complete documentation package, verifies compliance with criteria, and scores performance across all quality areas. Queries and clarifications may be exchanged during this phase.\n\n7. Receive certification decision: DGNB evaluates the auditor's submission and awards the certificate at Bronze, Silver, or Gold level based on the total score achieved. Certification is typically valid for 3 years for buildings in use.\n\n8. Maintain and renew: For ongoing certification (especially buildings in use), prepare for periodic re-certification by tracking operational performance data and updating documentation at renewal intervals.

The DGNB System evaluates buildings across six core quality areas, each weighted to reflect its contribution to overall sustainability performance:

1. Environmental Quality (ecology): Covers life cycle assessment (LCA) of global warming potential (GWP), ozone depletion, acidification, eutrophication, and primary energy demand. Also assesses risks to the local environment, responsible resource use, and biodiversity impact. This is one of the most heavily weighted areas, reflecting DGNB's commitment to genuine environmental performance rather than proxy metrics.

2. Economic Quality: Evaluates life cycle costs (LCC) including construction, operation, maintenance, and end-of-life costs over a defined reference period. Also considers value stability, flexibility for future use changes, and commercial viability — distinguishing DGNB from purely environmental rating systems.

3. Sociocultural and Functional Quality: Assesses thermal comfort, indoor air quality, acoustic performance, visual comfort, user control, accessibility, design quality, and the building's contribution to public space and urban context. This dimension ensures buildings genuinely serve their occupants and communities.

4. Technical Quality: Reviews fire safety, sound insulation, building envelope quality, ease of cleaning and maintenance, deconstruction and recyclability, and technical system quality. Emphasises long-term durability and adaptability.

5. Process Quality: Evaluates the quality of planning and construction processes — including project preparation, design integration, construction site management, and commissioning. Rewards projects that embed sustainability from the earliest planning stages.

6. Site Quality: Assesses the location's access to public transport, local amenities, risk exposure (flooding, noise), and the microclimate. Site quality is assessed but typically not included in the overall certification score — it is reported separately as contextual information.

Each criterion is scored on a scale of 0–10, and weighted scores are aggregated to determine the overall performance level: Bronze (≥35%), Silver (≥50%), or Gold (≥65%) of the maximum achievable points.

The DGNB Certificate is the dominant green building certification in Germany and holds a strong position across German-speaking Europe (Austria, Switzerland) and Scandinavia. With over 10,000 certified and registered projects in more than 30 countries, it ranks as the second-largest sustainable building certification network globally by membership, behind only the US Green Building Council's LEED ecosystem. In Germany specifically, DGNB is the de facto standard for premium commercial and public construction, frequently required or preferred by institutional investors, public procurement bodies, and major developers.

Globally, DGNB competes primarily with LEED (dominant in North America and internationally) and BREEAM (dominant in the UK and parts of Europe). In Germany and Central Europe, DGNB generally outperforms both competitors in market share and local credibility, partly due to its governmental co-development origins and its alignment with German engineering culture's emphasis on technical rigour and life-cycle thinking. BREEAM has a stronger foothold in the Netherlands and UK; LEED is preferred by multinational corporations seeking a globally recognised label.

Demand for DGNB certification is growing, driven by several macro trends: the EU Taxonomy for sustainable finance (which requires buildings to demonstrate environmental performance), ESG reporting obligations for listed real estate companies, and tightening EU building energy performance regulations. DGNB's explicit alignment with EU Taxonomy criteria and its ESG Verification offering position it well to capture this regulatory tailwind. The DGNB Academy's training platform — with over 9,000 qualified experts in nearly 60 countries — also supports international expansion, though DGNB's brand recognition outside Europe remains limited compared to LEED.

The DGNB was founded in 2007 in Stuttgart, Germany, by a coalition of leading figures from the construction and real estate industry, academia, and government — including the German Federal Ministry of Transport, Building, and Urban Affairs as a co-founding partner. The organisation was established in response to the growing international green building movement (LEED had launched in 1998, BREEAM in 1990) and a recognition that existing systems did not adequately reflect German and European priorities around life-cycle thinking, economic sustainability, and technical quality. The DGNB Certification System was formally launched in 2009, initially focused on new commercial construction in Germany.

Since its founding, DGNB has expanded significantly in scope and geography. The system now covers more than a dozen building use types and project categories, including renovation, interiors, districts, construction sites, and exterior spaces. International expansion accelerated through the 2010s, with national partner organisations established in countries including Denmark, Bulgaria, Austria, and Luxembourg. By the early 2020s, DGNB had grown to over 2,800 member organisations and achieved recognition in more than 30 countries. Key milestones include the introduction of the DGNB Diamond award for climate-positive buildings, the launch of ESG Verification services aligned with the EU Taxonomy, and the development of the SHIFT global initiative to promote sustainable architecture in the Global South. The system undergoes regular criteria updates to reflect evolving scientific knowledge, regulatory requirements, and market expectations.
