A combination aviary and bird-watching platform in China’s Suzhou Taihu Lakeside National Wetland Park, this stunning conceptual design by Margot Krasojević Architecture utilizes piezoelectric energy to move parts of the structure, mimicking birds in flight. At the heart of the dome, a high tensile steel loom acts as a gallery for birds, while the primary structure is made from stainless steel spine beams that move and sway like feathers.
Piezoelectric cells are connected to a motor that harnesses movement to produce an electrical current, making the entire structure self-sufficient. The cells then respond to the overall mechanical stress generated by the structure and create an electric charge, which in turn runs through a dichroic filtered electrochromic glass modifying the transparency and luminosity of the facade. Responding directly to the density of bird movement, the facade appears to “flutter” as the environment changes.
Thanks to the reflective, fluttering facade, the structure appears to partially disappear into its wetland surroundings. The dome protects birds from flying into the glass cladding by projecting ultrasound signals from the surface. Extra electrical energy generated by the piezoelectric cells is used to control the dome’s temperature, humidity and building filtration, allowing the structure to essentially dictate its own ecosystem. The humidity is filtered and ecologically purified to be pumped back into the surrounding wetlands through the aviary’s dome.
Visitors are led into the wetlands and connected to the building entrance through a helical ramp that unfolds across the aviary. This hydraulic runway ramp glides along within the building, rather than touching the building envelope, to guide visitors as they walk among the birds. The ramp can lower and raise to take visitors to different heights within the interior; this can offer clearer views. The pile grid is anchored through concrete to enable it to rise and fall according to the substructure movement, all while maintaining equilibrium inside the aviary.
