This is something truly amazing, Xian Min Zhang sent in a video to Gizmodo of his company's latest project, a 30-story tall, 183,000-square-foot hotel built in just 360 hours. 360 hours is just an amazing 15 days. What is more impressive is that it's not just a simple hotel built, there are some great features built-in.

The hotel was built near the Dongting lake, in the Hunan Province, China, by Broad Group, a Chinese construction company who specializes in sustainable architecture. The building uses prefabricated modules (with a +/- 0.2mm precision in the fabrication process) mounted on a steel structure, with diagonal steel bracing.

What impressed me the most, are the following features of the building: it can resist a 9-magnitude earthquake (and was tested by the China Academy of Building Research), which is claimed to be five times more earthquake-resistant than conventional buildings. It is also five times more more energy efficient, with 6-inch thick glass curtain wall insulation and four-paned windows with built-in shades, a heat recovery system and 3-stage filtration air conditioning process that actually purifies indoor air to be 20 times (!) purer than the air outside.

Given that China has serious pollution problems, this is actually quite an amazing feat. On top of this, there's even air quality monitoring in every room. Amazing! The next question is, when will this company start opening up manufacturing plants across the world, and if labor is too expensive, when will they start shipping out virtually pre-built (in parts like Ikea) and building them everywhere. How can countries like America, etc take months, or even years to build something equivalent, and at times, with sometimes half or if any of these features.
