Around 800 trade visitors tour the passive house development in the Sino-German Ecopark in Qingdao every week. The construction project is highlighted as exemplary in the Chinese government’s current 5-year plan, and engineers, craftsmen and other builders are required to visit the site to advance the Chinese planned economy.
Wolfgang Frey is a regular presence in Qingdao. He gives lectures and organizes training courses with his team.
