Continuing our coverage of the Shanghai World Expo , we come to the Japan Pavilion , officially nicknamed the ‘Purple Silkworm Island’. Designboom  is on the scene in Shanghai and has captured some great images of strange-looking purple bubble. The lightweight structure is composed of a tubular metal support system covered in a purple membrane with integrated solar cells . In addition to its solar power generation capabilities, the pavilion features natural ventilation and innovative energy-efficient cooling technologies.

The Japan Pavilion  incorporates a number of sustainable building strategies to keep the building cool. An innovative Eco-Tube system was designed specifically for the structure to provide natural ventilation  and bring in daylight. Outside air is drawn through ducts underneath the structure past a basin of collected rainwater , which cools the air. Then the air is naturally pulled up through clear tubes in the structure, which disperse cool air into the exhibition rooms. Water is misted around the outside of the building to provide more cooling, and the structure is lit up with LED lights.
The Purple Silkworm Island is covered in a light purple pillow membrane , which lets some light naturally filter into the interior of the building. 20-30 kW of solar cells have been integrated into the membrane to generate electricity, and the interior of the pavilion also features a variety of energy and water saving technologies. To top it off, Japan showed its love for robots with a humanoid bot performing on the main stage.
