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.

Commissioning of electrical systems

Commissioning of electrical systems has become an integral and well-established part of the building design and construction process. However, as cities and states increasingly pass more stringent energy legislation while new technologies continue to present countless possibilities, building systems will get smarter and more interconnected—and the role commissioning plays in the built environment will continue to expand.

LED lighting and control system design considerations

Designers need to explore various approaches and requirements to lighting design as codes and standards are becoming more energy-conscious.

Designing lighting systems and lighting controls

Lighting designers must consider many factors when specifying lighting systems and lighting controls for their designs. In addition to considering the type of lighting fixture, they must also take into account daylighting, lighting controls, codes and standards, and other factors. To ensure these systems work as efficiently and effectively as possible, commissioning new systems (along with ongoing commissioning) is vital for success.

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.
