On Feb 16, a group of 22 South Koreans visited ZEGG, primarily to find out about our new heating system. The delegation were staying in Berlin and a coach brought them to Bad Belzig for their tour of ZEGG, where in spite of the icy conditions they spent almost two hours walking around the site, accompanied by Ina Meyer-Stoll. The excursion had been organised by a Korean teacher working at a university in Berlin, who chose ZEGG because of its suitability as an example of sustainable development.
