Sky City sounds like a very good idea indeed. Its high quality air filtration system & low energy temperature control would be very desirable. 'Nature' can also be brought into the building. The views are marvellous. No more traffic jams & long daily commute for many. Easy & leisurely to eat out, shop, bring up kids, & be well served by a hospital too. Hotel for visitors. I have high expectation that this will go very well indeed!

We shall see in a year's time.

Same old vertical slum justified with spin doctoring.

It is truly shocking that some of the description for this project include:
"higher quality of life"
"Close proximity to nature"
Most of the inner areas of the building will have no natural lighting, or natural ventilation. it is unlikely that an occupant will have much control over his environment. All these and others are associated with quality living. Furthermore, if you don't live on the bottom 3 or so floors, you're completely cut off from nature, especially if they pretend that this will function as a vertical city - most likely nobody will have much time to go outside. The daily commute to work is now merely vertical, mechanical. So much for health.

Editorial

Video from Broad Sustainable Building as reports suggest groundbreaking in June 


A true vertical city. This is the concept behind Sky City, a 838m-high tower destined for Changsha in Hunan Province and allegedly due to begin construction next month (June 2013). The team behind the project are Broad Sustainable Building (BSB), a Chinese construction group responsible for some of the swiftest building projects in the world including the 15-day construction of 30-storey hotel in Dongting Lake.

BSB is planning to realise Sky City - which will rise 10m above the world’s current tallest tower, the Burj Khalifa - in only 7 months using prefabricated components in a plan that has been scorned by many industry professionals. The video below shows a fly-through of the proposed design from construction through to completion and was released on the Different Energy YouTube channel a few days ago. At the time of going to press, the video had had over 51,000 views.

The gross building area of the tower will be 1,200,000 sq m across the main 220-storey building and 4 much shorter wing buildings between 3 and 7 storeys in height. There will also be 4 basement levels totalling 130,000 sq m. Residential units will be located on floors 16 to 180 with 4,000 homes in total and 500+ hotel rooms are planned from floors 181 to 219, supported by clubs and restaurant facilities.

Staying in line with the ‘vertical city’ concept, Sky City will also include primary and middle schools, kindergartens, nursing homes and hospital clinics on levels 1 to 5 and sporting facilities including basketball fields, tennis courts, athletics fields and table tennis facilities both within the main tower and the 4 wing buildings. A series of roof terraces are also within the plans.

Sustainability has always been integral to BSB projects and the firm stresses that this project is no exception in the following statement: “[The design] drastically reduces dependence on transportation by integrated offices, residences, schools, hospitals, shopping malls and entertainments. It reduces 80% of energy consumption by utilising 20-inch wall thermal insulation, 4-layer windows, heat recovery fresh air system, LED lighting power generation by elevator descending and Combined Cooling-Heating-Power system.”
