The program involves the construction of Efficient Houses, the organisation of information events and the selection of pilot cities for a sustainable urban development project. The Deutsche Energie-Agentur (dena) – the German Energy Agency – announced the joint programme on the occasion of the most prominent green building conference in China.

"German-Chinese co-operation has taken an important step forward," emphasised dena’s chief executive Stephan Kohler. "The joint working group will decide on a suitable approach and concrete co-operation projects will show what can be done in practice. China is very interested in energy efficiency and German companies are the ideal partners to deliver it."

In Beijing, dena and its Chinese partners agreed on four new pilot projects: the construction of residential buildings in the cities of Zhuzhou (Hunan) and Ledu (Qinghai), the construction of two schools in Beidaihe (Hebei) and the refurbishment of an office building in Qingdao (Shandong). All in all, dena is now supervising over a dozen German-Chinese Efficient House projects. One of them was completed in Qinhuangdao (Hebei) in October 2013 and has received the new energy efficiency certificate of the Hebei province.

At the Green Building Conference, dena presented energy efficiency made in Germany, organising a "German day" on passive house technology and an exhibition stand for German suppliers. This year, the exhibition partners included Geberit, Luwoge Consult, Obermeyer, Siemens, Viessmann, Wilo, Xella and Zehnder. The "International Conference on Green and Energy-Efficient Building & New Technologies and Products Expo" took place in Beijing from 28 to 30 March.

The German-Chinese Working Group for the Promotion of Energy-Efficient Building in PR China was set up in 2006 and is supported by the construction ministries of both countries as well as by dena, the Center of Science and Technology of Construction (CSTC) and the Chinese Society for Urban Studies (CSUS).
