What are emergency, standby and backup power systems?

Emergency, standby and backup power systems are key to many nonresidential building types, and are designed by an electrical engineer. Depending on the building and its occupants’ needs, it may include backup, emergency or standby power systems -- or even all three. These types of power systems are dictated by codes/standards, building type and the owner's needs.

Power-generation systems in high-performance buildings

Electrical engineers must consider many factors when designing power-generation systems. Safety, maintainability, efficiency, code compliance, and economics play crucial roles in determining the topology of a power-generation system. Specific requirements for power vary based on building occupancy type, facility use, and critical function.
