Powering Subduct Fans

Monday, December 25th, 2023

This episode of the Electrical Building Design Show has David Robison and co-host Mark Robison, PE looking at the intricacies of subducts, focusing on their purpose, electrical power requirements, regulations, and the challenges facing electrical engineers in ensuring their continuous operation.

A Few of the Items Presented Include:

  • Sizing Battery Backups: Determining the appropriate size for a battery backup system is necessary and involves considering the continuous load of the fans, along with potential inrush and harmonics.
  • Maximizing Efficiency: Fan efficiency is important, but not all fans are created equal. Oversizing fans can mitigate noise issues, reduce power consumption, and offer a dual benefit in terms of energy use and system performance.
  • Electrical and Mechanical Coordination: Proper engineering coordination creates a balance between safety, efficiency, and cost, and is essential for making informed decisions on system design, backup power solutions, and fan selection.
  • And more…

The Bottom Line:

The creation of the subduct by mechanical engineers cleverly enhanced fire safety in buildings, and requires navigating the complexities of backup power, system design, fan efficiency, and staying informed with local codes and standards.

In the video below, David and Mark provide more detail on these small ducts within ducts, and their seamless integration into modern buildings.
