建筑遮阳（Solar shading Devices） Building sun shading.Txt, if there is afterlife, to be a tree, standing eternal, no sad gesture. Half in the soil, quiet, half in the wind flying, half fall cool, half bathed in sunshine, very silent, very proud, never rely on never looking for. Discussion on building energy saving design from building shading 2010-9-26 17:38 from the network [big, small] [Print] [I want error correction] First, the significance and definition of building energy efficiency The energy consumed in the construction process, commonly referred to as building energy consumption, accounts for a large proportion of the total energy consumption. 30 years of reform and opening up China, created the world human miracle in architectural history: 1985-2004 20, the completion of the construction area of 10 billion 560 million m2, accounting for the existing building area of 1/4, is expected to be 2020 new construction area of 30 billion m2. However, at present, more than 95% of Chinas existing buildings are high energy consumption buildings. In 1992, construction energy consumption accounted for 15% of the total social energy consumption, 27.5% in 2000, and will increase to 40% in 2020. If the transportation and consumption of raw materials are added, the building energy consumption may be as high as 50%. This reflects not only the improvement of living standards in urban and rural areas, but also reflects the rapid development of Chinas construction and energy demand situation. Building energy efficiency has become one of the mainstream of energy-saving wave in the world because of the important proportion of energy consumption in the total energy consumption of the society. Building energy conservation technology has become one of the focuses of the worlds construction technology development. Two, the significance of building shading At present, the state has vigorously advocated green buildings, energy-saving buildings, and promulgated a number of specific specifica
