China: dena certifies first efficiency class A office building

Province of Hebei steps up cooperation with dena

The Deutsche Energie-Agentur (dena) - the German Energy Agency - has certified the first Chinese office building complying with the new energy efficiency standard issued in the Province of Hebei. Using around 75 percent less energy than normal new buildings in China, the six-storey building in the provincial capital of Shijiazhuang will house a new research centre for energy efficient construction. Based on experience gained in Germany, the standard was developed jointly by the Province, the Center of Science and Technology of Construction (CSTC) and dena.

"The implementation of this pilot project in the Province of Hebei is a clear sign in favour of energy efficiency," said Andreas Kuhlmann, dena's Chief Executive, in Shijiazhuang on Friday. "The building is an excellent example for architects, planners, administrators and tradespeople. On top of this, the research centre will ensure that standards tested in the new building will spread around the province."

The office building provides around 14,500 square metres of usable floor space and has achieved energy efficiency class A under the new Hebei standard thanks to careful planning and construction, from the building envelope to systems technology and the use of geothermal and solar energy. In the course of the building's planning and implementation, dena carried out several on-site training sessions and quality control measures to ensure the success of the project. The construction exclusively involved processes and technologies suitable for the Chinese market that can easily be emulated.

At their meeting in Shijiazhuang, representatives of the Province of Hebei and dena's Chief Executive Andreas Kuhlmann also agreed to step up cooperation between dena and the Hebei Academy of Building Research. This will include further projects involving construction and certification according to the jointly developed energy efficiency standard. The two parties are also planning to cooperate in the field of training and advanced training of regional experts.
dena is involved in close to 30 energy-efficient construction pilot projects in China. Aside from the office building in Shijiazhuang, dena has already certified four large residential buildings in the cities of Qinhuangdao (Hebei), Harbin (Heilongjiang) as well as Rizhao and Weifang (both in Shandong). It is dena's intention to open up the energy-efficient construction market in conjunction with Chinese and German partners.

On Saturday, Andreas Kuhlmann will hold further talks with representatives of the Olympic city of Zhangjiakou situated in the North-West of the Province of Hebei. Zhangjiakou is acting as a pilot city in a dena project on sustainable urban development. At the meeting, energy issues concerning the preparations for the 2022 Winter Olympic Games and the development of a renewable energy demonstration area by 2030 will be discussed.
