Big Buildings in World

The City of Dezhou in China has successfully bid to host the 4th of a biannual series of world solar conferences, and will do so in the largest building ever to be almost entirely powered by solar in the world. It has over 800,000 square feet of space inside.
Nearly all of the energy use inside the giant building is solar powered. Green building techniques such as advanced roof and wall insulation reduced the energy requirements of the building by 30% (below comparable buildings) and the solar arrays on the roof provide 82% of the remaining energy.
The 800,000 square foot building contains 75,000 exhibition centers, scientific research facilities, meeting and training facilities, and even the hotel that international trade show attendees can stay in, right in the same building, to further reduce their carbon footprint.
The intention of the conference center is not just to provide a venue for solar trade shows, but to provide a forum for international ideas exchange on solar energy scientific research and technology development, and sustainable urban development using solar.
Solar development will play an increasing part in China’s development. With even major Chinese cities like Shanghai suffering energy shortages in recent years, the urgent need to save electricity is apparent. For China one solar solution to that is the use of solar to heat water, probably the cheapest solar application.
China now leads the world in residential rooftop solar thermal hot water development, reducing its electricity needs. Three out of every four solar thermal collectors worldwide are now both made and installed in China. That market has grown a steady 28% a year in recent years.
The Burj Khalifa (formerly known as the Burj Dubai) opened today, officially becoming the world's tallest building. Standing at a height of 828 meters (2,716 ft) tall, the United Arab Emirates (UAE) landmark has more than 160 stories, the most of any building in the world. The tower has a 360 degree observation deck on the 124th floor and plays host to the world's first Armani Hotel. The Burj Khalifa will ultimately become a community of 12,000 residents all using the building's self-contained facilities for work, home and recreation.
Designed by Copenhagen based group of architects, BIG, the REN Building is expected to be a recognizable landmark for the 2010 World Expo in Shangai, China. As you can see in the image, the building is shaped by two buildings that unite on the water. The building will mix-use the function of hotel, sports and conference center.
There’s a lot of debate about what the tallest tower in the world currently is. Some say the Taipei 101, at 1671 ft to the tip of it’s spire, is the world’s tallest tower, whereas we might argue that the Sears Tower, at a whopping 1731 ft (and 110 stories), still takes the prize. However, if the enormous, 13,000 ft X-Seed 4000 structure ever gets built in Tokyo – it will win the worlds-tallest-building competition hands down and leave its puny competitors in the dirt.
Looking eerily like Mt. Doom in the above rendering, the mountain-like X-Seed 4000 represents a utopian eco-vision for a self-contained high-rise city in the Tokyo harbor – powered mainly by solar energy. Aesthetically inspired by nearby Mt. Fuji, the behemoth building would measure 13,123 feet tall with a 6 square-kilometer footprint, and could accommodate five hundred thousand to one million inhabitants.
