Green Generation Solutions (GreenGen), Bethesda, Md., retrofitted assisted-living facilities over several years to be greener and more energy-efficient, according to a December article in Facility Executive.
Solid-state lighting, such as light-emitting diode (LED) technology, promises significant short-term opportunities, notably in the retrofit market. However, many industry stakeholders are concerned about long-term risks LEDs present as they continue to gain acceptance.
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.
With tens of thousands of parking garage structures containing hundreds of millions of spaces to accommodate the nation’s 135 million-plus registered passenger cars, the U.S. parking garage sector is a robust market that accounts for significant real estate in cities and towns nationwide.
According to the U.S. Department of Energy (DOE), in 2010, more than 75 percent of lighting systems installed in the commercial building sector were fluorescent, with the majority installed in recessed troffer luminaires.
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.
The opportunity in the LED retrofit market is enormous, and the missteps made in rushing other energy-efficient lighting to market (e.g., the compact fluorescent lamp) are less likely to slow market growth this time around.
Market research and consulting firm Navigant Research has found consumer motivations and government influence drive the demand for innovative new products to save energy through energy-efficiency upgrades in older buildings.
