3. Designs for pumping technologies
By making correct pump and piping selections, systems can operate at or near peak efficiency, avoid cavitation, and maintain a long service life. With each system type a multitude of options are available to a designer or engineer; but within these, the best option must be selected for a given application.
4. Understanding transfer switch operation
Consulting engineers should understand transfer switch construction, performance requirements, selection criteria, and desired operation to ensure that critical systems and equipment are supplied with reliable backup power when needed.
5. Designing with NFPA 101-2015
NFPA 101: Life Safety Code dictates a great deal for all building types, including egress, features of fire protection, sprinkler systems, alarms, emergency lighting, smoke barriers, and special hazard protection.
