Systems

 

 

Integrated electrical and low-voltage systems of all types—inside and outside a building—encompass the range of work that electrical contractors do. The articles in this section highlight different types of work, from security, fire and life safety, to traditional electrical power and distribution, to lighting, cabling and more. 

Updating a lighting system to improve energy efficiency seems like a no brainer. The facilities in the space will be improved, and it saves the owner money. What could be the problem with that?

Imagine storing summer heat. Renewable energy has always been about the art of the possible, turning the obvious and plentiful into a reliable source of clean fuel. If the wind, waves and even the almighty sun can be harnessed for generation, almost anything else can be captured, too.

Safety has always been one of the biggest knocks against nuclear power. A standard adopted in March 2016 by the Institute of Electrical and Electronics Engineers (IEEE) and the International Electrotechnical Commission (IEC) could further the industry’s neverending quest to address those concerns.

Last month, we published our annual construction forecast. We’ve been doing this gig for quite a while, and, if there’s a running theme connecting every forecast, it’s uncertainty. It’s not exactly the weather, and we give those guys and gals grief for their unreliability, too.
