There are two basic approaches for improving the energy efficiency of an existing ligh

36、ting system: retrofit or redesign. Retrofitting the existing luminaires will be the more common approach. However, on projects where the existing illumination or lighting equipment no longer suits the space or application, redesign is the bet-ter choice. A thorough assessment is necessary to determi

37、ne if one (or both) of these methods is advan-tageous over the other.When upgrading lighting in any space, it is important to know the recommended practice and illumination levels for the occupant programming. The IES pub-lishes many standards on lighting applications, and a competent lighting pract

38、itioner/designer may be able to help with specifying accepted illumination levels in the building. There may be a nominal cost, but it is a sound investment to get the lighting upgrade project right the first time. When working on a lighting upgrade project, one must always be aware of the delicate

39、balance between quality lighting and energy savings. When too much focus is placed on energy savings, quality may suffer.1.1 AudienceThis document is intended for commercial and insti-tutional building owners, lighting practitioners, man-agers, facility engineers, energy service companies, retrofitt

40、ers, and utility representatives considering a lighting upgrade.This document is written in general terms; every lighting project is a little different because of the wide variety of architectural and luminaire styles.According to the U.S. Department of Energy Buildings Energy Databook, 2010, lighti

41、ng systems often con-sume about 26% of the electrical energy used by the building, depending on the type of building, location, age, and other factors.1A lighting upgrade gener-ally offers one of the most cost-effective and easy means to reduce operating costs with a return on investment that is acc

42、eptable to the financial manag-ers of the facility. However, appropriate illumination levels and light quality must also be achieved along with the energy savings. Figure 1 illustrates why it is imperative to not lose employee productivity in the name of energy savings. If completed properly, a ligh

43、ting upgrade may actually increase occupant productivity!1.2 Lighting Upgrade: Retrofit or Redesign?The two basic ways to improve energy efficiency for an existing lighting system are retrofit and redesign. A retrofit, due to financial considerations, is the usual type of upgrade. Sometimes, however

44、, it may make more sense to do a redesign. It is important to assess as soon as possible which process will be the most effective; it may be that both strategies are required in different parts of the same project. Retrofit is a method to modify a lighting system to lower the operating costs and/or

45、improve the performance of that system based on efficiency and the task performed. Redesign is a method to modify a lighting system which will intentionally modify the goals of the existing lighting design. This may include an entirely new lighting distribution pattern, relocating and installing new

46、 luminaires and new circuits and controls to meet the new objectives.While this document concentrates primarily on the retrofit process, concepts will be presented that may also be useful in redesign projects.A lighting upgrade may result in energy savings when one or more of the following situation

47、s exist: Older technologies such as T12 fluorescent lamps and magnetic ballasts or older HID (high intensity discharge) systems such as mercury vapor or probe start metal halide are in place Illumination levels are too high Glare is a problem Inefficient optical components such as lenses, louvers or

49、her light level than is actually needed New lighting controls are added to existing, or new luminaires Potential lowering of ambient light levels and the addition of low level task lightingNote that a lighting upgrade is also an opportunity to increase light levels that are too low for the current tasks performed in the space. Sometimes upgrades can also create energy savings when lights levels are too low, depending on the magnitude of the accompanying improvement in energy efficiency.Refer to the current version of the IES Lighting Handbook, 10th Edition and the mos
