In order to make sustainable construction applicable in a practical mannor, measurable and thus comparable, the DGNB has developed its own certification system. The system was first introduced to the market in 2009 and has been continuously developed since then, and is now not only considered the most advanced in the world, but is also internationally recognized as the Global Benchmark for Sustainability.
The certification system is available in different variants for buildings, districts and interiors. As a planning and optimisation tool, it helps all those involved in construction to implement a holistic and sustainable quality.
In terms of content, the DGNB System is based on three key paradigms that set it apart from other certification systems available on the market:
Within the certification process, the entire life cycle of a project is consistently taken into account and instead of individual measures, the overall performance of a project is evaluated.
The DGNB System is based on the three central sustainability areas of ecology, economy and sociocultural issues, which are weighted equally in the evaluation. The DGNB System evaluates the location as well as the technical and procedural quality with a holistic approach. The performance of these qualities can be evaluated by means of certification criteria. These are individually tailored to different types of use and can be applied to new buildings, existing buildings, refurbishments and buildings in use.
Every building, from planning to deconstruction, goes through different phases, which are linked to different requirements and conditions. These can be accompanied by the DGNB certification system in terms of a holistic sustainable construction method. The following diagram shows exactly which phases these are.
By reducing cost-intensive risks, the application of the DGNB System contributes, to a high degree, of future security for construction projects. The independent certification process serves to ensure transparent quality control. As proof of this quality in construction, a DGNB certificate in platinum, gold or silver can be obtained. A bronze certificate can also be obtained for sustainable building operations or existing buildings.
The DGNB has defined target values for each criterion. These are weighted differently depending on their use. The aim is to always promote a uniformly high quality of buildings, quarters or interiors.
With a share of over 80 percent in new construction and over 60 percent in the overall commercial property market, the DGNB is the market leader among providers of certification systems in Germany. The DGNB is the European leader in the certification of quarters. More than 8,700 construction projects have already been planned, built and certified according to the principles of the DGNB in more than 35 countries worldwide (as of 31.12.2021).
When used abroad, the DGNB System is adapted to regional conditions. In doing so, the DGNB works closely with leading local organisations in the individual countries. An overview of all partners can be found here.
