Recreation & sport facilities &

business places serve only

residents to avoid traffic from

the outside

SKY CITY STRIVES FOR TRANSPORT MINIMALIZATION

In the past, Super Tall Buildings were

dependent on land transportation,

whereas Sky City is just the opposite

(60% energy saving from the window)

External solar shading

(30% energy saving in summer, warm air isolation) Fresh air heat recovery

(80% energy saving from the heat loss of ventilation)

CHP (cooling, heating & power) application

(means no need for energy supply for cooling

& heating operation )

HVAC energy consumption 90kWh/m2a

(equals 9- liter oil)

BSB energy efficiency technologies have beenvalidated in over 30 buildings

One building cuts 120,000 tons of CO2emissions

for the earth

SKY CITY STRIVES FOR ENERGY CONSERVATION

In the past, Super Tall Buildings consumed much more energy than

conventional buildings, whereas Sky City is just the opposite

SKY CITY STRIVES FOR HEALTH

PROTECTION

In the past, Super Tall Buildings were prone to

sick building syndrome (cross contamination

for all floors & rooms), Whereas Sky City is not

only immune to SBS, but also much cleaner

than outside

There are city squares, childrens playground, basketball,tennis & badminton courts, swimming pool, theater,cinema, park, flower nursery located in all the sky parks.86,400m2vertical organic farmother urban recreation &sport facilities and countryside scenes

8,000m2of open sky gardens. Additionally, residents can bepart of the thick trees as long as they go out, as theskyscraper has emptied much space for green lands

Living space enjoys flexible configuration, the span is

15.6m x15.6m

Residents enjoy all-exclusive cultural & health facilities,organic areas

In the past, Super Tall Buildings dependent on lift

transportation lacked public spaces, whereas Sky City

offers residents with an open city-like space for play

SKY CITY STRIVES FOR HIGHER CONSTRUCTION QUALITY

Conventional buildings were constructed by day laborers ,

whereas Sky City is manufactured by professional workers

SKY CITY STRIVES FOR RAPID CONSTRUCTION TURNOVER

In the past, Super Tall Buildings demanded 5-10 years to construct, whereas Sky

City needs only 7 months (after foundation), its size is twice as large as the largest

building in the world

90% factory-made (on-site construction work

is only 10% of conventional construction work)

Flooring, ceiling, water & electricity supplies,

HVAC & etc are fitted in a 60m2module. Walls,

windows and doors are stacked on a module.

Bolt connection for all of on-site installation

20,000 workers work for 4 months in the factory

3,000 workers install onsite for 3 months

BSB fast building technologies have been

validated in over 30 buildings

20 sets of self-climbing craneswork around theclock

SKY CITY STRIVES FOR A LONGER LIFE SPAN

The durability of steel structure building has

been proven by Eiffel Tower, whereas Sky

City with its steel structure free from the rain

enjoys better anti-corrosion treatment than

Eiffel Tower did

Steel materials are different from concrete, with noaging issues

Cold galvanizing anti-corrosion technology is used

Tight thermal insulation prevents condensation

corrosion

Anti-corrosion treatment/each 60 years, as durable

as a new one

After decommissioning, all steel materials can be reused

Stocking resources for future generations, leaving

no wastes behind

SKY CITY GIVES AN IMPETUS TO THE

NEXT STEP IN CHINESE URBANIZATION

Not all wrong deeds can be undone, urbanization in a

country is once for all. Sky City with its No.1 Altitude has

championed its energy & land conservation concept

in the future development of Chinese urbanization

Buildings ought to be developed towards the

sky and towards mixed-use community

Urbanization can not be materialized at the

cost of land and environmental pollution

China can tread on a road of Energy-saving,

Land-saving Urbanism

SKY CITY STRIVES FOR THE GLOBAL NEW

SIGNPOST OF SUSTAINABLEDEVELOPMENT

The world population is increasing at 1.8% year by year and CO2

emissions at 5% year by year. In the near future, environment

pollution & climate change may breach the critical point while

humans become helpless. When Sky City with its strong signal

comes into being, is like a huge signpost on the vast seas

The global urban territory is not supposed toexpand only, but can be contracted as well

The global vehicles are not meant to

increase only, but can be lessened as well

The global CO2emissions can be controllable

Humanity can find a real approach to sustainable

development for higher life quality and lower

impact on the environment
