China is currently home to the world’s largest solar energy building, named the “Sun Dial”. It opened in Shandong Province in north China in 2010. It has a total area of 75,000 square meters and has been constructed keeping green ideas in mind.This vast fan-shaped compound in China is the “largest solar-powered office building in the world”. Located in Dezhou in the Shangdong Province in northwest China, the 75,000 square meter structure is a multi-use building and features exhibition centers, scientific research facilities, meeting and training facilities, and a hotel – all of which run on solar power.The design of the new building is based on the sun dial and “underlines the urgency of seeking renewable energy sources to replace fossil fuels.” Aside from the obvious sustainable nature of the solar panel – clad exterior, other green features include advanced roof and wall insulation practices resulting in an energy savings of 30% more than the national standard. In addition, the external structure of the building used a mere 1% of the amount of steel used to construct the Beijing Bird’s Nest.
