The DGNB Certificate
Setting the Benchmark
Integral Design Goal definition in the early stages of design State-of-the-art technology Intelligent concepts If these requirements are fulfilled, the certificate is attainable
© DGNB 2010 |13
Pre-Certification: Advantage of Integrated Planning
Improved risk management More transparency and process clarity in planning and construction Higher security in achieving the performance goals of a building upon its completion Higher building quality Pre-certification promotes improved building optimization and offers marketing advantages
© DGNB 2010 |14
The Path to Certification Registration of the building with the DGNB
Definition of goals for building performance according to gold, silver, or bronze
Use of pre-certification for marketing
Documentation during planning and construction phases according to DGNB regulations
Evaluation of planning and construction documentation by the DGNB
Award of the DGNB Certificate

DGNB International Application
Country-Specific Adaptation A country-specific adaptation facilitates the certification process. The system is always adapted in close cooperation with local experts.
Adaptations have been (or are currently being) undertaken in countries such as Austria, Switzerland, Denmark, Bulgaria and China. Other country adaptations are currently being prepared, e.g. for Brasil and the Ukraine. 23 | © DGNB 2011
