Sustainable guidance, construction, certification

Sustainable building - what it means

Creating structures that provide an enduring benefit for investors, building owners, users and the environment is short-hand for sustainable building. Certification procedures on an international level revealed that sustainable buildings are more effective than conventional buildings. Seals of approval are considered as quality criteria, increasing the value of a property, improving its marketability, contributing to risk minimisation, considering user requirements, producing comparability, and last but not least, serving environmental protection. Sustainable buildings are characterised by a holistic and highly future-oriented approach. Based on the life-cycle concept, the buildings meet clearly defined high-class quality standards, from planning to eventual deconstruction.



Sustainable projects – the benefit
Sustainability is far more than a short-lived trend. The demand to buy or rent certified objects is continuously growing. Sustainable buildings create a win-win situation including substantial benefit for many parties involved.

Project planners and building owners benefit from
  • quality assurance throughout all phases - planning, construction, utilisation and demolition of a property
  • a bargaining tool for negotiations with tenants, financial institutions and public authorities
  • early consideration and consistent implementation of a concept to achieve a balanced cost-benefit relationship
  • a minimised vacancy rate and investment risk
  • better selling and renting opportunities with higher rates of return
Users benefit from
  • healthy, comfortable rooms increasing the occupants' sense of well-being and therefore, productivity
  • a property representing your corporate strategy of social responsibility
Investors and buyers benefit from
  • certified quality of a building confirmed by an independent authority
  • low operating costs and higher sales prices
  • documentation of building qualities to structure real estate portfolios
Financial institutes benefit from
  • a risk management instrument with regard to tenancy and change in value
The sociocultural environment benefits from
  • provision for neighbourhood interests
  • creative assets that are ecologically compatible
The building and real estate industry benefits from
  • incentives to develop innovative and competitive concepts to realise energy-efficient real estate
  • higher standards for building materials safe for the environment and health
  • incentives to optimize legal requirements through certifications

What customers say - project “Stadtfenster Dortmund“
ZIAG Immobilien AG comments on the DGNB certification of its existing property by DIEDERICHS.
“Sustainable buildings rank among the most attractive properties - equally popular with building owners, investors and users. "Stadtfenster Dortmund" at 'Hansastraße' – a premium location in Dortmund – is one of the first existing buildings in Germany to be certified by the German Sustainable Building Council, DGNB. As a pilot project for DGNB certification of existing properties, it has established new benchmarks in the area of sustainable building. In DIEDERICHS we have found a partner for auditing, according to DGNB and for the support of our ambitious goals. DIEDERICHS relates to our overall concept of developing innovative, responsible and future-oriented projects, which is an inevitable condition for constructive and productive cooperation. I was particularly impressed by the experience that DIEDERICHS always keeps an eye on the overall success consistently adhering to cost and deadlines. The completion of ’Stadtfenster’ with a rentable surface of around 4,000 sqm is planned for autumn 2010. I am already looking forward to that event as well as to future cooperation with DIEDERICHS.”Dr. Oliver Bäumler, CEO of ZIAG Immobilien AG

Bernd Boetzel, CEO and founding member of DGNB

"As early as 1995 we started to deal with the issue of sustainable building, e. g. in the project 'Federal Ministry of Economics and Technology'. The target was to undercut the regulations of the Heat Regulation Ordinance by 30 %. An essential part of the ecological deliberation in connection with the planning and construction process was, besides adherence to schedule and budget, the utilisation of renewable sources of energy. Those experiences have been applied to many public and private projects and further developed. It was a logical step to commit ourselves as initiator and foundation member of DGNB. In the last years we could make a decisive contribution to the establishment of Sustainable Building as a future-oriented quality and marketing tool. Our credo is that building for the future requires a change in thinking!“
