China has recently unveiled the world’s largest solar-powered building. It is situated in Dezhou, Shangdong Province in northwest China and covers an area of 75,000-square-meters. The design of the building is based on a sun dial and its architectural design features the Chinese characters for sun “日” and moon “月”. Its white exterior was intended to represent clean energy.
The building is multi-functional, serving as space for exhibition centers, scientific research facilities, meeting and training facilities and a sustainable hotel.
The building will be showcased to the whole world during the 4th World Solar City Congress in September 2010. The building’s pioneering solar energy and power-saving technologies, a few already patented, include a number of technical advancements that will push forward the mass application of solar energy. The clean and green ideas are not confined to the massive solar array only but can be spotted in the whole building complex.
The building will procure 95% of its energy needs from alternative energy sources including a 5000 square meter solar panel array on the building complex, a solar hot water production facility, a solar desalination plant and a solar energy theme park.
The city of Dezhou has been designated as a "solar city". In this city, solar energy is all pervasive. It powers everything from street lighting to tourist cars. Most of the city's 5.5 million people have opted for solar hot water systems.
Dezhou is installing new solar heaters on 1 million roofs. The low-tech devices capture the sun's energy heating water used for bathing or washing. So far, more than 100 villages in the city had set up solar energy bathhouses. The figure is expected to rise to 1,000 by 2010,Wu said. According to Greenpeace, in 2007, 800,000 people in Dezhou had jobs in the solar panel industry. Greenpeace predicts that this figure is expected to grow to 1,500,000 by 2020.
Green technology in China is growing in popularity. About 200 million Chinese people will be using solar energy water heaters, over an area of about 150 million square meters, up from current 100 million square meters by 2010. China accounts for around 76 percent of the world market of solar heaters.
