Passive House Technology and Experience Center

Qingdao, China

The Passive House Technology and Experience Center is one of the first buildings constructed in Sino-German Ecopark Qingdao. By the consistent implementation of the passive house standard, an outstanding example of a highly energy-efficient building with the highest standards of comfort and using was created.

Qingdao is a large port city located between Beijing and Shanghai, where extreme climatic conditions with high fluctuations are prevailing. During the summer months, the climate is tropical with temperatures around 30 degrees Celsius and up to 90 percent humidity. In winter, European climatic conditions can be found.

These climatic conditions make energy-saving technologies extremely necessary, e.g. for dehumidification. Within the internationally staffed planning and development team ROA - Rongen-Tribus-Vallentin under the direction of Michael Tribus Architecture (Lana, South Tyrol), the Passive House Institute Dr. Feist Innsbruck performed the energy planning, optimisation and quality assurance as well as the official Passive House certification.

A lighthouse project was realised on a total usable area of almost 7,800 square metres which is exemplary for the entire region and for many follow-up projects in China.
