At the general meeting of the German Sustainable Building Council (DGNB) in the German city of Stuttgart on 9th May 2014, the Board of Directors and Executive Board reported on the growing importance of the certification of buildings by the DGNB. In 2013, seven years after the establishment of the DGNB, over 600 buildings in Germany and 721 buildings worldwide have been certified in accordance with the DGNB standard. 30 city districts have now also been certified and the certification of industrial locations is currently in the pipeline.
Herrmann Horster, a member of the DGNB Board of Directors, estimates that nowadays, around one third of newly constructed office and administrative buildings in Germany are certified in accordance with sustainability criteria. Horster assumed that the DGNB assessments are joined by approximately 200 to 300 evaluations carried out in Germany in accordance with the US LEEDS system or the British BREAM system. PVC products are assessed according to the DGNB standard without any prejudice if they have an EPD (environmental product declaration) which allows to calculate the sustainability footprint of a building. In recent years, PVC processors and their associations have therefore developed EPDs for window profiles, flooring and pipes. At the event in Stuttgart AGPU was represented by Werner Preusker. AGPU has been a member of the DGNB since it was first established and is continuing to look for examples of buildings with PVC products that have been evaluated as sustainable for its own website.
