Sky Cities will make healthier, cleaner and economically stronger cities

Broad Group is going to build the tallest building in the world by February 2013.

There are currently six factories in China in different provinces. BROAD Group also franchisees in India. These franchisees have made full payment for the transfer of technology which costs US$34 million for a population of 10 million and US$50 million for a population of 50 million. Their first factory produces 120 million square feet of factory mass produced building each year. Enough for ten 220 story Sky Cities.

They are on track to achieve the 30% market share of the world construction market by 2020. They have 5 joint ventures and factories and had targeted ten joint ventures by end of 2012. They are on the path to achieving 100 joint ventures by 2020 and having 70 factories producing 8 billion square feet of mass produced buildings.




Environment and Health Benefits

The construction conserves energy of up to five times compared with that of a conventional construction, and provides air that is 20 times purer than the traditional buildings through our innovative air purification system. They use less concrete.

Construction dust causes about 30-40% of the dangerous 2.5 micron PM and 10 micron PM (particulate matter). This is especially true in China. The factory mass produced method gets rid of 99% of the dust from construction. This will save a lot of lives. Outdoor air pollution causes 300,000 deaths per year in China. This could save 100,000 lives per year in China in the 2020s.


Buildings use 50% of the raw materials used each year in the world and 40% of the energy

If all building were made this way the system could reduce the raw material usage to 10% and energy usage to 8% of world usage.

Radical reductions in material usage and rapid increases in building energy efficiency will have a hugely beneficial impact on energy and the environment.

The 15 story building uses 30 kilowatt hours per square meter each year for heat and air conditioning.

Broad has already built the 50 Story (163 meter tall) Horizon hotel in Beijing.

They also indicate that the system can enable up to 8 floors to be built per day. They built the a six story expo pavilion building for the Shanghai 2010 expo in 1 day.

The first building built using these methods was a three story building on August 21, 2009.



Transformed Cities

Being able to build skyscrapers with three to ten times lower cost and up to 900 meters in height could cause a boom in taller skyscrapers.

There are 200 skyscrapers (152 meter definition) in the United States now and there will be about 800 skyscrapers in China by 2016.

Success with mass production of over 50 story buildings by Broad Group at lower prices could cause an increase in skyscrapers by ten to twenty times by 2025. By 2020, Broad Group and partners will be able to produce 700 Sky Cities every year. They could hold 70 million people at high Asian densities or 20 million with larger western standard units.

There still needs to be the demand for the office and other building space to justify the increased supply. Commuter and other transportation systems would have to be built up for higher density cities.

Shanghai and New York have comparable real estate prices. Having highrise apartments with 3000 square feet of living space that cost about $200,000 would be far more demand to draw commuters living an hour or more away who are paying similar or higher prices to live in the suburbs.

Even in Manhattan the high rises are now mostly 30-50 stories tall. Broad Group would enable 250 stories for comparable costs.

The Trump Chicago cost $847 million for 92 stories and about one fifth of the square footage.

Swapping out and upsizing the high rises in Manhattan would enable a population of 7 million in Manhattan instead of 1.5 million.

Clearly China will transform their cities first. Each Sky City would have a lot of people commuting inside the building from the apartments and condos to the offices and stores in the same building. This will also reduce the usage of cars and fuel with electric elevators. The world's fastest elevator go at about 40 mph or 6 floors per second.

Again this will boost air quality, reduce pollution and save energy.

Reduced commute times will increase productivity and boost economies. Increasing the reachable (within one hour) population will boost productivity and increase economic activity.

It will be re-urbanization or Skyscraper 3.0. Like the shift from 4 story buildings to 20 story buildings 100 years ago.
