During the visiting, Wolfgang Frey, director of Frey Architekten gave a presentation on low-energy passive house buildings and eco-city to visitors. According to the assignments of Economic Development Office of Qingdao Sino-German Eco-Park Management Committee, Mr. Frey explained the main factors in sustainable buildings and the building concept in eco-city, also enhanced the cost and benefits of low-energy passive house buildings. After the presentation, Mr. Frey accompanied with the delegation visited residential regions both in Riselfeld and Vauban districts in Freiburg. Mr. Xue highly praised the “people-oriented and harmonious community” design concept. Barrier-free design and  harmonious community concept are reflected from every corner in residential area. Each community is a small “sponge city” and every residential building with the attentively design of collecting rain water to common green area. Mr. Frey also mentioned how they saved cost at the same time achieved all necessary measurements by using the multi-functions of construction components. And from building materials to construction, highly pay attention on environmental protection. This idea won highly praise from Mr. Xue. As a response,
