Underfloor power distribution can create a web of wires that can restrict airflow below the raised floor, which can create hot spots and cause you to overcool your data center – an unnecessary expense. Overhead busways are more energy efficient because they do not hinder airflow, allowing your cooling system to work as intended. However, if best practices are followed, you can mitigate the risk of impacting airflow and energy efficiency with an underfloor cabling system. Just keep in mind that any move, addition or change to the cabling infrastructure disrupts the airflow and efficiency.
In addition to being energy efficient, busways are also more cost and time efficient compared to a traditional power distribution system, such as underfloor cabling. With an underfloor power distribution system, you need to have an electrician physically terminate power whips from the RPP/PDU to the cabinet. Because tap boxes are factory assembled, you eliminate the time and costs associated with onsite wiring to build circuits. While a busway power distribution system will require greater investment up front, it will pay off quickly with any type of move, addition, change or new deployment into your data center.
