In the widening embrace of renewable energy, cities have become a catalyst. For example, San Francisco recently approved an ordinance requiring solar panels on all new residential and commercial buildings constructed in the city beginning in January 2017.
It’s that time again when we call on expert pollsters to help us learn more about our readers and the work they are doing in the field. More than 2,400 of you responded to our questionnaire earlier this year, through snail mail or online, describing the work you did in 2015.
With an estimated 1–2 billion fluorescent sockets installed in commercial, industrial, institutional and retail applications across North America, the market for T8 technology remains strong, though new LED T8 replacements are giving traditional fluorescent technology a run for the money.
It has been another monumental and transitional year for physical security systems. For low-voltage contractors specifying security, the breadth of products has changed, and solutions-deployment methods have evolved even more.
This past April, Tesla Motors CEO Elon Musk grabbed headlines with the introduction of two battery-based energy-storage products from the new Tesla Energy subsidiary he claims will “fundamentally change how the world uses energy.” Perhaps even more important to Musk’s ambitious goal is the anticipat
Lighting is a mainstay of electrical construction. The U.S. Energy Information Administration estimates that lighting accounts for 15 percent of the total electricity consumed in the residential and commercial sectors.
Across the country, electrical contractors (ECs) are on a mission to increase their installation efficiencies, save labor costs and provide the most robust security to customers even in the toughest environments.
Mobile lighting systems powered by hydrogen fuel cells are cleaner and quieter and now have a proven track-record in applications like nighttime construction, sports and entertainment events, and airport operations, making them ready for commercialization and broader use.
Commercial Controls Corp., Valencia, Calif., has about 30 employees who work out of three locations in California and one in Nevada. Fred Scripture, who continues to be the owner and president but is no longer as active in the day-to-day operations, started the company in 1993.
Cooperation, coordination and conversation can pay off. That’s what the team behind the energy upgrade of Hilton Los Angeles/Universal City discovered when the hotel underwent a $7 million energy-saving retrofit, the biggest property-assessed clean energy (PACE) commercial project in the nation.
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.
