Bank of America Plaza is one of the most prestigious office properties in Los Angeles. Completed in 1974, it was the first high-rise structure to tower over the downtown cityscape. Today, it is a model of energy efficiency, featuring cutting-edge technologies that minimize power consumption and utility bills. Brookfield Properties has significantly invested in Bank of America Plaza modernization over the past three years. Brookfield had plans to upgrade the lighting equipment in the skyscraper’s parking garage and was exploring options when California Retrofit, Inc. (CRI), introduced them to the latest breakthrough in ballast technology. Unveiled in 2008 by Universal Lighting Technologies, DEMANDflex™ ballasts feature an adjustable ballast factor so that installers can “tune” ballasts to the exact power level required for the customer environment. Using a temporary tuning tool, the installer sets a maximum power level for each circuit of ballasts, which can be as low as 50 percent of full power. This eliminates the common problem of over lighting an area and wasting energy.
