Pacific Northwest Laboratory`s Lighting Technology Screening Matrix

Pacific Northwest Laboratory has developed the Lighting Technology Screening Matrix (LTSM), a software tool to evaluate alternative lighting retrofit technologies according to life-cycle cost. The LTSM can be used to evaluate retrofits for most configurations of fluorescent, incandescent, high- and low-pressure sodium, metal halide, mercury vapor, and exit lighting systems for any level of operation, electricity price, discount rate, and utility rebate. This tool was developed, in support of the Federal Relighting Initiative as part of the Department of Energy`s Office of Federal Energy Management Program (DOE/FEMP) to assist federal government facilities in their efforts to comply with the 10 CFR 436 mandated life-cycle costing for energy equipment investments. The LTSM has been used in the course of seven site modernization projects. These projects consisted of determining the cost-effective, energy-efficiency potential at military installations. Each project treated the entire military installation as an integrated system, proposed a large number of potential efficiency projects affecting all end-uses and fuel types, and analyzed the cost-effectiveness of each project. The LTSM was used for the lighting portion of these projects. Lighting was, overall, one of the major areas of potential efficiency improvements, accounting for over 30% of the cost-effective resource. Altogether over $43more » million worth of cost-effective efficiency investments were identified, worth an estimated $6 million annually in energy, demand, and operations and maintenance (O&M) savings. This paper describes the LTSM and demonstrates its application in a case study at one of the federal installations analyzed.« less
