Shandong has built the world's largest solar office building on November 27, 2009, the world's largest solar office building was unveiled in Dezhou, Shandong. This solar energy building, named "Riyuetan · weipaida national copper, lead and zinc quality inspection center, is built on the basis of the original Anhui copper based new material industry cluster window service platform", with a total construction area of 75000 square meters. It integrates display, scientific research, office, conference, training, hotel and other functions, and uses solar energy heat to account for about 80% of the water supply, heating, cooling, photovoltaic power generation and other building combined technologies of interior decoration, It is currently the world's largest high-rise public building integrating solar thermal, photovoltaic and building energy conservation

Its roof and exterior walls are made of polystyrene insulation board with a thickness much higher than the current national standard, and the overall heat transfer coefficient is greatly reduced, about 30% lower than the energy-saving standard; In particular, the most common doors and windows, skylights and curtain walls are used, and the temperature screen energy-saving glass and BIPV temperature screen photovoltaic modules are used. The heat transfer coefficient is reduced to the national energy-saving standard because the low-carbon steel deforms greatly when pressed and does not break half
