Electrical construction technology is an important component of intelligent building. As the main platform to support the development of intelligent building, it reflects the advantages of the application of electrical automation technology in intelligent building. In view of this, the paper focuses on the main technical points of electrical construction technology construction in intelligent buildings by literature comparison and theoretical analysis. In the foundation construction, main construction, interior decoration, equipment installation stage, from the integration of intelligent application platform to the analysis of technical solutions, it makes a more detailed description of the application of intelligent construction technology in intelligent buildings.
