It is necessary to add equipment components, such as power and communication cables, air conditioning pipes, water supply and drainage pipes,
It is not possible in space to rely on the existing duct space for these expansions. In particular, it was impossible to replace the water supply / drainage pipe that was driven into the frame.

Therefore, in order to secure the space, it is necessary to remodel the building itself so that the duct space is widened, for example, and it is enormous cost to achieve the intelligentization at the same time as the repair of the outer wall surface. Therefore, the current situation is that, in general, the existing building is abandoned as an intelligent building only by renovating the outer wall.

In view of such circumstances, the present invention makes it possible to inexpensively achieve the intelligent building of the existing building when the outer wall surface of the existing building is refurbished by the curtain wall, so that The purpose is to provide a method of renovating existing buildings that has been able to increase value.

[0007]

The method for remodeling an existing building according to the present invention, which has achieved the above-mentioned object, has a predetermined distance between the outer wall portion of the existing building and the outer wall surface through a supporting bone. It is characterized in that a space wall is formed and a curtain wall is installed, and equipment members such as a power cable and a communication cable for realizing a function required for making intelligent are arranged in the space part.

[0008]

In other words, the outer wall of the existing building is refurbished with the curtain wall, and at that time, a space is formed between the outer wall of the existing building and the curtain wall, and the intelligent function is realized in this space. By arranging equipment members for, in the state where these can be easily exchanged, and further, for example, without widening the duct space, or without modifying the building such as diverting the elevator shaft to the duct space, Intelligent building of existing buildings is achieved.
