As energy-saving automatic lighting controls become more popular for retrofit options in existing buildings, electrical contractors may find themselves in a position of estimating energy savings to justify owner investment.
Estimating lighting control energy savings is challenging, as actual savings depend on application characteristics, such as occupant behavior, building design, site orientation, daylight apertures, interior reflectances, device settings and level of commissioning.
Electrical contractors that are planning to enter the emerging energy services market should have a solid business plan to guide their expansion. Getting into this market is a must because customers today are looking for energy conservation, efficiency, production and reliability services.
The electrical contractor (EC) should build its energy services business on four distinct categories that, together, reduce energy use and expenses, increase facility efficiency and productivity, improve the environment, and provide a reliable energy supply that meets the business’ requirements.
Since the days of thomas Edison more than a century ago, electricity has flowed through the grid in one direction. Power is centrally generated, transmitted, distributed within cities to buildings and consumed immediately.
With lighting and communications technology evolving rapidly, lighting manufacturers are under pressure to determine how to best reach out to and train busy electrical contractors (ECs) on new and existing products.
With electricity demand in the United States predicted to grow by at least 40 percent by 2032, business could be impacted by higher operating costs and reduced profits from increased energy demand and constrained supply, a decline in sales of energy-using products, a loss of competitiveness in energ
Steps No. 8 and No. 9 of the energy services project delivery process involve procurement, installation, and integration of materials and equipment into operational systems to meet the customer’s energy conservation, efficiency, production and reliability needs.
For the electrical contractor (EC), finding a role in the smart grid shouldn’t be a matter of “wait and see.” Now is the time to prepare for this growing opportunity. If your work involves building automation and lighting controls, you are well on your way.
Fuel cells are an evolving technology and a current new market for the electrical contractor (EC). As a result of research and development, fuel cells have become feasible to implement with greater capacity, reduced costs, increased reliability and improved efficiency.
With the Institute of Electric Efficiency reporting more than 36 million smart meters installed from 2007 through May 2012 and a target of 65 million by 2015, it appears that smart meters are here to stay.
As we enter the final month of the presidential election campaign, the political rhetoric remains heated. Among the many issues to be debated, renewable energies and the federal policies that support them will no doubt feature prominently.
More than 8 billion lamps illuminate the United States, accounting for nearly 20 percent of all electricity consumption in the nation, according to a study released by the Department of Energy (DOE). The “2010 U.S.
As the use of renewable power, electric vehicles (EVs) and the smart grid become more widespread and integrated, one challenge also becomes more apparent: storage. Thankfully, the experts are on it. This summer, the U.S.
Is it possible that some T5 lighting fixtures are perfectly efficient? One might get that idea based on some efficiency ratings of 98–100 percent, although it might not seem possible. Such a rating must be a mistake, right? But it’s not.
The ongoing quest for more efficient, greener power seems to touch on almost every aspect of modern life, including cars, home electricity, manufacturing and building construction. Even lighting has come under scrutiny. In that regard, a recent report by the U.S.
One of renewable energy sources’ biggest challenges is the intermittency of power generation. Finding a way to store power for later use helps make renewables more practical for tying into the grid where demand does not always coincide with the wind or the rising sun.
