This is the first building in human history which combines almost all
environmental friendly, comfortable and secure elements. So, we call it:
Sustainable Building

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.

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.

    6 days to build a hotel? Sorry, but I just don’t believe that it is safe. I think you’re more likely to end up with tragedies like this, where an entire apartment building catches on fire as if it was made of balsa wood.

    I am a structural engineer, but I am not sure how those diagonal braces are supposed to work in terms of seismic resistance. Earthquake design in this country usually allows some damage to occur in the bracing without having any tearing or rupture or other sudden failure mode. I don’t see a mechanism in those braces that will accept the type of movements that an earthquake will impart to a building that height. In this country, you are not allowed to have earthquake braces connect into the sides of the columns (K-bracing). I am pretty skeptical that this building would peform very well in an earthquake, but I don’t have a very good look at it. There is also quite a lot of bracing on that building so that may help out.

    I should note that I have been biased on Chinese know-how by the pictures of this building in Shanghai that just fell over . . .

    I especially love the hollow piles with no rebar!
