The DGNB System has existed in Germany since 2009. These include for example the American LEED system (short for Leadership in Energy and Environmental Design), the French HQE (Haute Qualité Environnementale), CASBEE (Comprehensive Assessment System for Building Environmental Efficiency) in Japan and the Green Star system in Australia. A variety of other countries have also developed their own certification systems. The system in the UK, the Building Research Establishment Environmental Assessment Methodology (BREEAM), was the first of its kind when it was introduced in the 1990s. On an international level, there are a large number of certification systems spanning a diverse array of approaches and underlying objectives. There are many projects, particularly larger ones, where certification is considered a given and seen as key tool of management. At the same time, certification should provide incentives to promote more sustainability in building environments during the planning and construction phases of properties. The DGNB believes that certification should address the key factors that determine sustainable construction methods and make these measurable, comparable and thus available on demand for customers. In Germany, it is the German Sustainable Building Council, or DGNB.Ĭertifying buildings is an instrument that is established worldwide as a means of evaluating and thus also promoting sustainable building. Over the years new organisations have been set up in more than 100 countries, such as the Green Building Councils, which provide the movement with a platform on a national level. A large number of non-profit organisations, state programmes and private initiatives are now committed to greater sustainability in the built environment. But if you take a closer look at the obvious overlaps between the systems, there are actually a number of fundamental differences, so it's not quite right to consider them synonymous.įor about a quarter of a century, there has been a worldwide movement dedicated to the promotion of sustainable building. – the similarities and differences between building certification systemsįor many people, the three leading international systems for certifying sustainable buildings – DGNB, LEED and BREEAM – are sometime used in the same breath and the public perception is that they're largely interchangeable.
