Application of BIM technology in energy-saving design of green building

Nowadays, the energy consumption of the building industry accounts for a large proportion of the total energy consumption, in order to achieve sustainable development, energy conservation, energy-saving concept of green buildings emerged. Green building energy-saving is from the beginning of the design to construction and then to the operation of the whole life cycle, the use of sustainable development concept of green building energy-saving technology, so that it becomes a land-saving, water-saving, material-saving, energy-saving, to provide people with a healthy, applicable and efficient use of space, and natural harmony and symbiosis of the building. In the Information Age today, it is inevitable to use computer to assist people to work efficiently, and BIM (building information model) technology is a kind of 3D information as a carrier to assist the architectural industry design, construction, operation of technical means.
