To do. This integrated BIM model is a 3D model of the entire building including rooms, corridors, stairs, elevators, and the like. When the architect of the building saves the integrated BIM model in the server device 200, the building designer converts the data into a 3D-shaped building database model (in FIG. 2, a reduced-weight integrated BIM model) with a reduced data capacity. The user of the building obtains this lightweight integrated BIM model via the Internet using the terminal device 100 such as the smartphone 100-1, the tablet 100-2, or the personal computer 100-3.

When a user of a building virtually uses this light weight integrated BIM model, route information indicating the route that the user of the building has moved in the light weight integrated BIM model, the order of shops to visit, etc. The data is stored in the server device 200 as data (usage information in the present embodiment) indicating the usage status of the building. This allows building designers to optimize store layouts and elevators and escalators and other elevators that can be moved within the building with less travel distance based on stored usage information. Can be proposed during building design and business planning.

  In addition, as shown in FIG. 2, since the BIM parts of the store including product information such as photos and prices and sizes related to the products provided by the store are arranged in the light weight integrated BIM model, the use of the building The person can also make a purchase reservation for the product. In this way, it is possible to virtually operate a store in a building using the light weight integrated BIM model. Here, since the information on the product that the user of the building has reserved for purchase from the store is stored in the server device 200, the architect of the building, the store branch of the store, etc. can also perform the latest trend analysis on the product. It is. Therefore, it is possible to determine store plans and product purchases before the building is completed.

Can be proposed. Furthermore, the store occupant can simulate the actual store arrangement by moving and arranging the products to be displayed in the store in the light weight integrated BIM model. Furthermore, when operating virtually using the light weight integrated BIM model, the elevator equipment, lighting, and the like are obtained from the usage information stored in the server device 200 (for example, data such as the staying time and travel route of the building user). It is also possible to calculate the optimum specifications of building equipment such as air conditioners and power supplies. The architect of the building can also calculate the running cost at the stage before completion by feeding back the result to the design of the entire building.

  Furthermore, in the BIM system in the present embodiment, even after the building is completed, the user of the building can use the light weight integrated BIM model on the operation screen. For example, it is possible to provide a route search service based on usage information (for example, product purchase history and travel route) acquired when a building user uses a light weight integrated BIM model on the operation screen. is there. For example, a user of a building uses the terminal device 100 to input a search condition such as a purpose (for example, a toilet, a shoe store, moving to an upper floor), a destination (for example, a store name) or a desired product. In addition, it is possible to obtain a route search result. At that time, it is also possible to alleviate the congestion in the building by storing data such as search conditions and usage information of all the users and providing route guidance that is not crowded. In addition, when a user of a building visits the building, it is possible to present the optimal store visit route by inputting all the purposes such as what to do with the building or desired products into the terminal device 100.
