Ark Hotel Construction time lapse building 15 storeys in 2 days

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:
