Today, energy managers everywhere are compelled today to implement energy-efficiency strategies to offset high costs caused by growing plug loads and rising energy prices. In a typical operational environment, general illumination costs account for as much as 30-40% of annual electrical energy use. Other sources of energy consumption include cooling, ventilation and refrigeration. On average, commercial buildings use 14.3 kilowatt-hours (kWh) of electricity per square foot annually at a cost of $1.47 per square foot. According to the EPA, a 10% reduction in energy costs can increase their profit margin by 16% annually. When planning store renovation and equipment upgrade options, many retail operators are examining strategies to “green” their buildings and implement sustainable operations. By simply by upgrading to or installing new energy efficient lighting systems any commercial facility or office building can return literally hundreds of millions of dollars per year in needless electricity payments for general illumination back to their bottom-line.
