Sustainability is a top priority at Hanse Haus: DGNB Gold certification as standard at Hanse Haus

Build a sustainable
prefabricated house

In Germany, houses are rated primarily according to the criterion of energy efficiency, and are subsidised by the government through the Kreditanstalt für Wiederaufbau. Of course, energy consumption is an important criterion when building a home, but it should not be the only one.

If many other criteria besides fuel consumption are important when buying a car, the client’s requirements concerning architecture, the interior, technology, variability, safety, customisability and trust in the manufacturer should also be closely examined and objectively evaluated when building a house.

DGNB certification for evaluating buildings


Since its founding in 2007, the German Sustainable Building Council (DGNB) has developed criteria for assessing buildings – initially for multi-storey residential buildings and offices, but now also for single-family homes. It summarises these criteria in the Sustainability Plan of the DGNB.

The following criteria are used to assess a building’s sustainability:

  1. ecological quality
    emissions measurements, primary energy consumption etc.
  2. economic quality
    lifecycle costs, flexibility of use etc.
  3. socio-cultural and functional quality such as user comfort, health, functionality
    indoor air quality, individual floor plans, burglary protection, thermal insulation etc.
  4. technical quality such as fire and acoustic insulation
  5. process quality, i.e. the quality of planning and construction as well as
  6. quality of location
    building site, transport links, proximity to schools, medical care etc.

DGNB Silver, DGNB Gold and DGNB Platinum – certification for sustainable housebuilding

DGNB certification

For new buildings, the award begins with DGNB Silver certification for houses that fulfil a total of 50% or more of all the criteria.

If a building fulfils 65% or more of the criteria, DGNB Gold certification is awarded.

To qualify for DGNB Platinum certification, a project must fulfil at least 80% of the criteria in total.

Moreover, in each sub-category except for “place of construction”, at least 35% of the criteria must be fulfilled for Silver certification, at least 50% for Gold, and at least 65% for Platinum certification.

You can find out more about the DGNB’s sustainability criteria on the website of the DGNB.
