Benefits of certification

The DGNB Certification System is a second-generation system compared to other international certification systems: Assessment revolves not only around ecological aspects but also includes a holistic examination of the entire life cycle of a building or urban district.
What is interesting from an economic point of view is that sustainable buildings retain their value longer while having lower operating and maintenance costs. Investigations have shown that the risks of vacancies are minimized for sustainable buildings and rental income can be increased. In turn, this leads to better market prices and higher resale values for the property. Sustainable building is therefore a value driver and not a cost driver. This was also shown by an investigation by the consulting company Drees & Sommer: the extra financial cost for DGNB Certification is between 0 and 4 per cent of the construction costs. The additional costs for planning and consulting are even less than 0.5 per cent.

The benefits for users

Higher quality of life. Lower ancillary costs.

  • Healthy users: The DGNB System takes the health and well-being of building users into account and helps to reduce illness.
  • Lower costs for users: The DGNB System focuses on the building’s overall life cycle from the outset, lowers costs and optimizes processes in operation. Sustainable planning can thereby reduce ancillary costs in the long term.
  • For future generations: DGNB certified buildings consume
    fewer resources during construction, have lower greenhouse gas emissions and largely can be recycled. In thus reducing waste, they make an active contribution to protecting the environment.

Advantages for building owners and investors

Higher value. Lower risks.

  • Quality from the outset: As from the early planning stage, the DGNB Pre-certificate reassures building owners and users that the building will achieve its ultimate performance targets. 
  • Equal consideration for economic aspects: The economic sustainability of a building is seen as being every bit as relevant as its environmental, sociocultural and technical performance.
  • Increased market opportunities: The DGNB Certificate increases a building’s sale and rental potential by providing owners and users with a clear indication of its superior quality.
  • Safeguarding further rentals: The ever-growing demand for certified buildings minimizes the risk of vacancies.
  • Simplifying funding: Properties likely to qualify for DGNB certification often secure loans more quickly and at better conditions.
  • International comparability: DGNB certified buildings are comparable at both national and international levels.
  • Precise assessment: Individual profiles based on the standardized DGNB System are available for different building types to provide the most suitable certification for the market in question.

Advantages for planners and architects

More efficient planning. Less time and effort.

  • Promoting integrated planning: DGNB pre-certification in particular supports integrated planning, providing early optimization potential for construction, management, conversion and dismantling with an emphasis on optimizing costs. This means that the focus of the project is on quality from the very beginning.
  • Targeted planning and monitoring: A systematic definition of sustainability targets based on DGNB criteria raises all stakeholders’ awareness at an early stage and serves as a central instrument for quality assurance during the construction phase.
  • Assessing overall performance: Rather than specifying individual measures, the DGNB System sets targets for measuring a building’s overall performance. In doing so, it actively promotes innovative building concepts.

The benefits for consultants and product manufacturers

Relevance of products used in construction. Clear guidance.

Clear innovation potential: For each of the relevant criteria, the DGNB System shows consultants and manufacturers the extent to which building products influence the sustainability of the project as a whole. In this way, products can be further developed and optimized from a sustainability perspective. Here, too, the focus is on the entire life cycle – and therefore on the long-term quality of products used in construction.

Special benefits with the DGNB Pre-Certificate

DGNB criteria should be incorporated in the planning phase as early as possible. Pre-certification allows a development to be optimized from a sustainability perspective from the very beginning as well as generating an official record of this process.

This approach offers a number of benefits with respect to planning, construction and marketing. By defining all key sustainability criteria early on, clear targets are established for each player in the planning team. This in turn increases transparency, improves risk management and ensures a secure basis for the planned performance targets – and for funding. And, of course, the recognized quality label increases the attractiveness of properties, thus improving their rental and sales prospects. This means greater financial security for building owners and investors from an early stage in the process.
