Executive Summary

Problem: Lighting in commercial buildings account for over 70% of the overall lighting elec-
tricity used in the United States. Rising energy and maintenance costs are hurting profits of
commercial and industrial facilities and their carbon emissions must be dramatically
reduced to halt global warming issues.

Background: Increasing energy efficiency in lighting systems will impact reducing the overall
environmental effects, such as greenhouse gas emissions, and CO2 emissions. The reducution
of greenhouse gas emissions and an energy-efficiency focus will be crucial to businesses in
the United States if the Federal Climate Change Waxman-Markey Bill passes, as businesses
will be taxed on greenhouse gas emissions.

Solution: LED lighting offers significant energy, maintenance and recycling savings. When
retrofitting with LEDs, with good lighting design and LED product selection, energy con-
sumption in most commercial and industrial facilities will be cut 50-80% while maintaining
improving lighting quality. Three factors are accelerating for the use of large scale deploy-
ment of LED products for general area lighting applications:

     1) Retrofitting an existing lighting system with quality LEDs will make the facility
         more energy efficient and yield costs. LEDs have the best return on investment
        (ROI) of any energy-efficient technology.
     2) The aesthetic quality of a facility’s environment will be enhanced and productivity
         increased without sacrificing the lighting system performance.
     3) Federal and state governments are making laws regarding lighting, and
         associations are taking action towards quality products. All to make the United
         States more energy efficient and responsible. With support and encouragement
         through grants, and departments such as the DOE, an LED lighting system becomes
         even more advanced and cost effective.

  • 3. White Paper:TFM 2.12.10 Executive Summary Problem: Lighting in commercial buildings account for over 70% of the overall lighting elec- tricity used in the United States. Rising energy and maintenance costs are hurting profits of commercial and industrial facilities and their carbon emissions must be dramatically reduced to halt global warming issues. Background: Increasing energy efficiency in lighting systems will impact reducing the overall environmental effects, such as greenhouse gas emissions, and CO2 emissions. The reducution of greenhouse gas emissions and an energy-efficiency focus will be crucial to businesses in the United States if the Federal Climate Change Waxman-Markey Bill passes, as businesses will be taxed on greenhouse gas emissions. Solution: LED lighting offers significant energy, maintenance and recycling savings. When retrofitting with LEDs, with good lighting design and LED product selection, energy con- sumption in most commercial and industrial facilities will be cut 50-80% while maintaining improving lighting quality. Three factors are accelerating for the use of large scale deploy- ment of LED products for general area lighting applications: 1) Retrofitting an existing lighting system with quality LEDs will make the facility more energy efficient and yield costs. LEDs have the best return on investment (ROI) of any energy-efficient technology. 2) The aesthetic quality of a facility’s environment will be enhanced and productivity increased without sacrificing the lighting system performance. 3) Federal and state governments are making laws regarding lighting, and associations are taking action towards quality products. All to make the United States more energy efficient and responsible. With support and encouragement through grants, and departments such as the DOE, an LED lighting system becomes even more advanced and cost effective. LED Lighting Retrofits 1

Superior lighting quality LEDs light up very quickly and are ideal for use in applications that are subject to frequent on-off cycling. Comparing LEDs to other light- ing technologies, fluorescent lamps tend to burn out more quickly when cycled frequently, where HID lamps require a long time before restarting. LEDs can very easily be dimmed either by pulse-width modulation or by lower- ing the forward current. In contrast to most LEDs - A Better Light Source light sources, LEDs radiate very little heat in the form of infrared (IR) that can cause LEDs create a better environment damage to sensitive objects or fabrics. Wasted Lighting is a critical component of energy use, energy is dispersed as heat through the base of especially in large commercial and industrial the LED. buildings. High-efficiency lighting systems reduce glare, which helps to reduce eyestrain, boosting oc¬cupant productivity. Electronic ballasts do not flicker or hum like magnetic ballasts, improving the quality of the facility’s environment. Light levels must be maintained at certain levels for particular surface areas.

To fully realize the cost savings, energy efficiency, and low mainte- nance LEDs offer, it is important to convert to LED with the most advanced and capable technology on the market. With performance, lifetime, cost, safety, and theft-deterrence advantages, LED lighting is the best choice when retrofitting with energy efficient tech- nology. Depending upon the technology being replaced, potential energy savings, rebates, and incentives, a lighting retrofit could be a low-cost implementation.
