DGNB System International
The DGNB System is a sustainability assessment system for the built environment, serving also as a tool for planning, designing, constructing, and operating built environments in a sustainable manner.
Developed in year 2009 by the German Sustainable Building Council (DGNB System is named after its German name “Deutsche Gesellschaft für Nachhaltiges Bauen”), the DGNB System has become a global benchmark for the sustainability due to its holistic approach and alignment with the regulatory framework of the European Union. It has proven to be an optimal tool for evaluating and optimizing the sustainability of buildings and urban areas.
The DGNB System provides a set of criterion catalogues and indicators with defined threshold values and verification methods. These tools can demonstrate the sustainability of a building, urban area (district), or interior, while also assisting investors, designers, and users of the built environment in planning, constructing, and operating it in a sustainable manner.
The DNA of DGNB System

4 main criteria catalogues the built environment in DGNB System

Since its establishment, the Green Building Council Croatia has been informing the professional community about the elements of sustainability. However, there is also a need to objectively quantify and valorise sustainability as a characteristic of the built environment through one of the internationally recognized systems and tools.
After a comparative analysis of the three most significant sustainability assessment systems, it was concluded that the DGNB System is the most suitable for the Croatian market due to the following reasons:
- It is the only system that originated in the European Union and is therefore adapted to the European regulatory framework.
- It is the only system that gives equal weight to each of the three ESG sustainability principles (environment, economy, and social) in the overall performance assessment.
For this reason, the Green Building Council Croatia became the national partner of the DGNB System for Croatia in October 2021.
In the evaluation process, the entire life cycle of the building is taken into account, from the planning and design phase, through construction, the operational phase (building use phase), all the way to the end of the building’s service life (demolition).
Depending on the fulfilment of performance indicators in the variable criteria catalogue, buildings can be classified into three qualitative levels: platinum, gold, silver, or bronze certification.
The DGNB System is aligned with the European Union’s regulatory framework and, as such, largely corresponds to the Croatian market. However, given market specifics, the DGNB System can be adapted to local conditions through the “adaptation list” approach, with the proviso that the fundamental principles of the DGNB System (DGNB System DNA) must not be compromised. Adaptations are proposed by auditors or consultants, with the approval of the national System Partner and DGNB as the license holder.

Since 2016, the Croatian Green Building Council has held DGNB Academy Partner status and, as such, has the opportunity to meet local needs and train professionals in the built environment on the criteria and evaluation methods for achieving DGNB certification.
There are currently 53 active DGNB-certified consultants in Croatia. View the list here:

Pilot Phase in Progress
During the pilot phase of adapting the DGNB system to the Croatian market, all clients, registered projects, and consultants stand to benefit. The inaugural DGNB certificate will be conferred upon the Matrix C office building in Zagreb.
If you aspire for your project to champion a sustainable and environmentally friendly future, seek out a Croatian consultant who can expertly guide you through the process. The DGNB certificate provides investors with market-recognized quality assurance, particularly significant in the current era of climate challenges. Users of these spaces also appreciate the significance of occupying environments that positively impact health, overall well-being, and the environment.
The pilot phase is well underway, and we invite you to join us as advocates for sustainable change!
DGNB Academy: Building Expertise
Since 2016, the Green Building Council Croatia has proudly held the title of DGNB Academy Partner. This distinction empowers us to address the specific needs of our local experts in the built environment, offering comprehensive education about the criteria and evaluation processes required to attain the coveted DGNB certificate.

EU Taxonomy Study: Climate change mitigation
The property market has quite a bit of catching up to do if it wants to work through the taxonomy criteria laid down by the European Union. This is partially because stakeholders lack the information they need to fulfil verification requirements. In addition, the way some of the criteria are currently formulated, they are practically impossible to fulfil. This is the conclusion of a recent study conducted by the DGNB in collaboration with partners from Denmark, Austria and Spain. It also includes concrete recommendations to the EU Commission and market stakeholders aimed at making it easier to apply the criteria in the future.
Life Cycle Assessment – a guide on using the LCA
These guidelines aim to promote the increased use of life cycle assessments in the planning process, by demonstrating the relevance and potential of this tool. Designers and building contractors are additionally provided with arguments for employing these methods as an optimisation tool as early as possible in the planning and implementation process, and the sustainability effects that can be achieved as a result of this are emphasised. Furthermore, the reader is presented with examples of how the results of life cycle assessments are communicated and can serve as supporting arguments for making more environmentally sensible decisions in the course of the planning process.
Circular Economy
In recent years the term “circular economy” has become more widespread and has also become a relevant topic in construction. The concept upon which the circular economy is based has great potential: The availability of resources should be ensured for future generations through their appreciation, as well as reuse and recovery. The circular economy is therefore an elementary building block of sustainability and it transfers sustainability to society and its individual sectors.
Framework for carbon neutral buildings and sites
In the Framework, the DGNB has compiled its definition of carbon neutrality as well as the corresponding explanations regarding procedures. The aim is to create clarity on the market and to educate all stakeholders with regard to effective optimisation approaches for reducing the CO2 emissions of their properties. Among other things, the Framework describes the rules for CO2 accounting of buildings and sites. It also serves as a basis for developing building-specific climate action strategies. Additionally, requirements and possibilities for CO2 reporting and quality assurance are presented.
