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.
Higher quality of life. Lower ancillary costs.
Higher value. Lower risks.
More efficient planning. Less time and effort.
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.
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.
