Before the connection of green analysis, to invite professional personnel to use the analysis software input data analysis, to take a different software to re-enter the data. Therefore, when the design changes are made, everything has to start all over again, so the cost is wasted. Therefore, the concept of green building only stays in the drawing stage, which cannot be reflected in the concrete construction. BIM technology can solve this problem, because the BIM model stores a lot of information, so no artificial input data as long as the BIM is adjusted to the intelligent analysis mode, you can carry out green intelligent modeling design work. After the analysis of the site and the environment, the architect can design a green style design matching the surrounding environment through the scientific design of the site. Through the simulation technology of BIM, green building design scheme of environmental protection is selected.
