The North German Centre for Sustainable Building (NZNB / www.nznb.de) is a centre for communication, learning and information on information, based in Verden (Lower Saxony, Germany). It is still in the phase of being set up. Building blocs of the centre are an exhibition about sustainable building, with tours and consulting for different target groups are being offered. Also, there is an ecological seminar centre; here trainings in areas such as straw-bale building, clay-building and ecological insulation are being offered. NZNB also is base for various businesses and organisations in the field of sustainable building (professional associations, planning offices, traders of ecological building material). This project aims at further devoloping the NZNB as a an organisation as a whole, but also in its various fields of activity. Therefore the staff-members want to learn from one of the most established and experienced centres for Sustainability Education in Europe, the Centre for Alternative Technology / CAT (GB). During a three-day visit 10 statt-members of NZNB will get to know CAT as a whole, and engage in dialogue with their specific counter-parts at CAT to learn about experiences made in fields such as management of the seminar-centre or running specific courses. The information gathered and the experiences made will be evaluated together. During the visit also future collaboration between NZNB and CAT will be discussed. Ideally this will result in joint projects in the future. After the visit - based on information gathered and experiences made - the participants will explore strategies and measures for the development of NZNB - as a whole as well as in the specific areas of activity. Part of this is the planning of professional training workshops for an international audience. Reports about the project will be launched on the Website of NZNB and local media.
