Level 9 Earthquake Resistance: diagonal bracing structure, light weight, steel construction, passed level 9 earthquake resistance testing 6x Less Material: even though the construction materials are much lighter(250kg/m2) than the traditional materials(over 1500kg/m2), the floors and walls are solid with surefootedness, airtight and sound-proofing 5x Energy Efficient: 150mm thermal insulation for walls and roofs, triple glazed plastic windows, external solar shading, heat insulation, fresh air heat recovery, LED lighting, yearly HAVC A/C energy consumption equivalent to 7 liters oil.
20x Purification: after 3 levels of purification, the purification efficiency for fresh air reaches 95%-99.9%; air exchanged 1-2.5 times per hour, and indoor air is 20x cleaner than out door air 1% Construction Waste: all components are factory made, construction waste, mainly package materials, result from on site set-up only and amount to 1% of the total weight of the building.
This is the first building in human history which combines almost all environmental friendly, comfortable and secure elements. So, we call it: Sustainable Building
June, Changsha Great City, 200 workers with more than 20 transport vehicles brought in a variety of factory production of building components, building a high 49.95 meters, covers an area of 610.83 square meters, the seismic intensity of 9 degrees steel business floor. The building components in the factory pre-production, the same day in the field "assembly" can be.
(...)
In order to build this building, ambitious spent nearly two years to design and supporting product development.

Technology has been key to the development of non-restricted Enhancing the Stability said, because there is no calculation of subsidies, this building cost around 3,000 yuan (332€) per square meter. Even if in the future to achieve mass production, can only reduce the project cost about 2,000 yuan (221€) per square meter. Now the cost of residential buildings of reinforced concrete average of less than 1,500 yuan (166€) / square meter.
