What are electrical and power systems?

Electrical and power systems are key to any nonresidential building type, and are designed by an electrical engineer. Depending on the building and its occupants’ needs, it may include backup, emergency and standby power systems. Other systems that come into play are wiring and cabling, switchgear, uninterruptible power supplies and fuses and breakers. Electrical engineers who design these systems must understand harmonic mitigation, electrical safety, smart grids and the various codes and standards that define them.

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.

Lighting controls: Know the updates, changes

There has been a move away from traditional lighting controls approaches, which have only incrementally improved over decades, and toward an entirely new way of thinking about, designing, and implementing lighting controls—wirelessly, with internet connectivity, and in an individually addressable capacity all at once.
