BIM provides power summary calculation and terminal level spatial drawing (from the sub distribution switchboard to the socket or the lights).
With BIM Electrical designers can visualize the electrical switchboard in the technical room: footprint and door swing checking.
BIM automatically incorporate electrical installation heating impact in HVAC sizing,
performing the best trade-off between all the building elements (structural, electrical, mechanical) to save energy
BIM automatically calculate the recyclability of the whole building including electrical part
BIM can get better coordination of electrical systems and prevent conflicts with other systems similar to plumbing, structural elements and mechanical systems
