On three faces of the new downtown Los Angeles headquarters of the California Department of Transportation (Caltrans), 2,000 innovative outdoor metal panel scrim louvers open and close in vertical banks.
Adjustable speed drives or ASDs, are often categorized as "sensitive" to power quality phenomena, which means ASD could also stand for "another sensitive device." I am still not sure what "sensitive" means relative to hardware. Susceptible seems like a far better choice of words.
Photovoltaics (PV) are semiconductors that convert sunlight directly to direct-current (DC) electric power. Photovoltaic technology has been used for years in specific applications where conventional utility service is not readily available or practical.
There's a growing urgency in the development of “green” or “smart” building, and learning to install its energy infrastructure-which is called integrated building systems (IBS) and involves tying together HVAC, electrical, security, lighting and fire alarm systems-could well be a boon to contractors
Modern technology makes it possible that whatever is detected can be electronically reported, and whatever is reported can be remotely monitored, and whatever is remotely monitored can be remotely controlled.
In 1993, government researchers concluded that a group of 12 states in the midsection of the country have enough wind energy resources to generate nearly four times the amount of electricity consumed nationwide in 1990.
Advances in lighting technology have produced a variety of new retrofitting methods and components that are transforming existing high-volume facilities and transportation infrastructure. By their very nature, retrofits are designed to enhance performance and provide significant energy savings.
The next generation of hotel security and lock systems will depend on two features—ease of access for the guest and ease of control for the hotel. As a result, there are some subtle shifts in the market that will change how electrical contractors do business.
You could not find two adjacent states taking more opposite approaches to electric markets than Maryland and Virginia. But they still have one thing in common that could be good for electrical contractors. Governors of both states have issued orders for conservation upgrades worth millions.
The National Park Service (NPS) is in charge of protecting our national parks. It only makes sense, then, that NPS is pushing for environmentally friendly lighting systems in those parks. Green Energy Parks, a joint program of the NPS, the U.S. Department of the Interior (DOI) and the U.S.
Are there jobs for you in the nuclear power market? According to the World Nuclear Association, a recent study determined that nuclear energy incurs about one-tenth of the financial cost of coal to produce electricity.
Photovoltaic (PV) modules convert sunlight into electrical energy that can be used to provide power for specific loads within a building in a standalone system or as a supplement to the building’s utility power supply in an integrated system.
Fuel Cells are in demand where power is in short supply Fuel cell technology is turning up in unusual places. As the utilities—as well as commercial and residential customers—seek energy alternatives, fuel cells are emerging wherever government assistance or reliability needs are the greatest.
Submeters are installed after the main utility meter to gain additional information regarding energy usage inside a facility, according to Don Millstein, president of Langhorne, Pa.-based E-Mon Corp. Estimates for the submetering market are primarily based on existing facilities, although U.S.
Can you imagine what it would be like to be the first person in the world to flip a switch actuating what could become revolutionary technology? A switch powering a device that will assist in reducing our dependence on imported fuel while at the same time decreasing emissions into the universe?
A large part of the nation has been spooked recently by regional energy crises. If necessity is the mother of invention, then perhaps recent price spikes, power outages and fears of terrorism are causing some people to assume more responsibility for their energy needs.
Electrical contractors working for utilities or interested in a growing niche market might do well to investigate opportunities in distributed energy resources (DER). They are parallel and stand-alone electric generation units located within the electric distribution system at or near the end-user.
