Passivhaus Bruck Changxing is the first residential building in the humid subtropical climate zone of southern China with approximately 95% energy savings. It was completed in 2014 and certified by the German Passive House Institute. Thus, it marks an important milestone for sustainable and innovative construction in China.

As a pilot project, Passivhaus Bruck demonstrates the potential of the Passive House standard and was developed in close coordination with experts from the Passive House Institute. Moreover, it is the flagship project of the company Landsea, which operates its research and development center here in Changxing.

The five-story building includes 36 studio apartments, 6 executive suites, and 4 model apartments. This allows interested families to experience sustainable living on-site and helps to dispel prejudices. The triple-glazed windows and fixed sun-shading elements protect against heat and ensure high living comfort.

Additionally, Passivhaus Bruck was awarded the Gold Medal at the World Green Design Award in 2014. It stands as an exemplary model for forward-looking, energy-efficient, and sustainable building in southern China.
