In order to promote the digital transformation of building electrical engineering

this study selects Internet of Things (IoT) perception

BIM collaborative design and artificial intelligence control algorithms as the representative intelligent technology

and constructs the application design method of "perception-collaboration-optimization". The monitoring accuracy is enhanced through the multi-sensor data fusion algorithm

multi-disciplinary collaboration and pre-emptive resolution of pipeline conflicts are achieved by relying on the BIM 3D model

and energy efficiency is dynamically optimized by combining a fuzzy neural network controller. The validation of engineering cases shows that the collision problem solving rate in the design stage reaches 92.3%

the construction efficiency is improved by 31.2%

and the comprehensive energy consumption in the operation period is reduced by 15.8%

which indicates that the design method can effectively support the digital transformation of the building electrical engineering and provide a feasible technical path for the industry.
