With the popularization and application of intelligent technology, many social industries have made great progress and changes, which not only promotes the overall social and economic development, but also provides a more excellent development opportunity for China's construction industry. However, in the actual intelligent building mechanical and electrical installation process, due to the influence of various objective factors, it is easy to have problems in the installation. Therefore, in order to ensure the installation quality of intelligent building mechanical and electrical equipment, this paper first clarifies the work content of intelligent building mechanical and electrical equipment installation; secondly, carries out in-depth analysis on the problems existing in the installation of intelligent building mechanical and electrical equipment; on this basis, puts forward the technical points of intelligent building mechanical and electrical equipment installation in the new period, for reference.
