Although the service life cost of the bus system is usually lower than that of the traditional wiring method, the bus system still bears a considerable cost compared with other structural elements of the water supply and drainage or HVAC system.
In addition, customized busbar equipment can be used to route the busbar system around obstacles, and the price of the power distribution system will be higher. Therefore, it makes sense to specify a busway before planning other elements such as plumbing and HVAC systems, as this will reduce the amount of custom equipment required, which will then make the busbar routing straighter and significantly reduce the cost of the project.
BIM is an excellent tool for improving the accuracy of busbar roads. Ability to create a central BIM model at the start of the project, which then enables parties involved to update the data center design to reflect the changes. This makes it possible to provide a digital copy of the entire data center, and then more simply and precisely identify the obstacles where it is necessary to lay out the busbar system to plan a more useful path.
The power distribution system of the data center needs to be designed flexibly to facilitate future expansion. This requirement is becoming increasingly important as the rate of change in the data center industry continues to increase. For this reason, it is necessary to plan the bus road for the potential future demand so that the road can be easily corrected to add additional power capacity if needed.
The road to confirm the busbar system depends largely on the location of the input power supply and the electrical equipment.
