The light-emitting diode (LED) offers energy savings, lower maintenance requirements and other advantages compared to incandescent sources. However, many LED products perform poorly with existing dimmer controls.
A limited number of low-voltage contractors specialize in the installation of sprinkler systems power and controls. For them, it provides a regular source of revenue that most contractors have bypassed.
In a recent training presentation, a question came up about the new identification requirements for automatically controlled receptacles. Does the marking need to be on the receptacle face, or is a marking on the faceplate in compliance?
Commercial buildings could cut their heating, ventilating and air conditioning (HVAC) electricity use by an average of 57 percent with advanced energy-efficiency controls, according to a year-long trial of advanced controls at malls, grocery stores and other buildings across the country.
Times are changing for the electrical contractor (EC). The trend even affects the basics. As Electrical Contractor focuses on the latest developments in cabling and controls, the 2014 NECA Show in Chicago, Sept.
Once known as demand-side management, the implementation of products and practices designed to modify electricity consumption are proven methods for electricity providers and consumers to control usage.
When commissioning a high-performance building, one element of lighting control is sometimes left out: the daylight harvesting system. It’s assumed such systems will work right out of the box after some simple calibration. Working is one thing, but working optimally is another.
As wireless deployments continue to keep electrical contractors (ECs) busy, installers are seeing increased diversity in the type and scope of these projects. One reason is the greater reliance on wireless networks. Another is the introduction of the latest wireless standard, 802.11ac.
The drive for networked building controls aimed at lowering energy costs and boosting efficiency is changing the market for providers. Business is growing as companies become installers and service providers in this industry.
While lighting control technology has proven to be a great means for reducing energy consumption, saving energy costs, and enhancing user satisfaction within a lighted space, it hasn’t always been smooth sailing.
After years of low compound annual growth rates (CAGRs) and limited innovation, the home security market is finally evolving with new and affordable security control products, and systems are becoming widely available, according to a November 2013 blog from Amdocs Inc., a software and service provid
Approved back in 2012, the ANSI/TIA-606-B labeling standard is taking its time catching on among electrical contractors (ECs). But, some advantages include better clarity and improved efficiency in the long run.
Big data, that slightly overwhelming concept where staggering amounts of information are gathered and analyzed in search of useful data nuggets, continues its creep into the building automation market.
Lighting and control technology advances and creative daylighting implementation are propelling green lighting practices. ECs are being called on to employ their technical and creative skills to install and program new products and technologies.
Wireless technology is certainly getting attention these days. We’ve covered the extensive range of new home automation and security products and systems often here in the pages of ELECTRICAL CONTRACTOR.
