Executive SummaryLighting in buildings remains a huge energy savings opportunity that is highly competitive with other Federal energy savings opportunities in terms of return on investment. The US Department of Energy's Federal Energy Management Program (DOE FEMP) is challenged with executive and legislative goals that are increasingly difficult to meet as energy efficiency becomes more challenging in the Federal market. Given these challenges FEMP must be selective when making programmatic investments; there must be a high probability of success and a clear path toward meeting energy savings goals. It is with these things in mind that the Lighting Business Case has been developed.Lighting technology is evolving at a rapid pace and yet standard practice with respect to lighting in Federal facilities has not similarly evolved. Federal facilities are generally slow to embrace new and emerging technologies due to a series of complex factors. The best lighting efficiency opportunities are underutilized in both retrofits and new construction largely because energy efficiency contractors are not sufficiently motivated or able to try new and unfamiliar strategies. This is not from lack of interest; their best intentions are thwarted by market barriers and obstacles such as lack of awareness, expertise, excessive risk, high costs, and procurement challenges. Intervention is necessary to realize energy savings and meet the legislated goals.This report presents analysis and data that has been used to determine high value energy savings opportunities, and provides a series of candidate (suggested) tasks to implement the opportunities indicated by analysis. Candidate tasks are shown to address market barriers and have performance metrics provided for measurement of progress against the goals. Analysis included detailed information about four specific high-value lighting technologies and their usages, projected market penetration into the Federal building stock, and the potential energy savings shown against FEMP goals.The results of the analysis show that the effect of strategic Federal efforts towards deployment of new and emerging lighting technologies is to almost double the natural penetration rate by the year 2014. The cumulative savings of the four lighting technologies is 14,000 Btu's per gross square foot as of 2014. This represents 72 percent of the overall goal of 2 percent per year across all Federal agencies, as directed by the Energy Policy Act of 2005. Return on investment information is presented for each of the four technologies.The Lighting Business Case provides solid support for programmatic investment decisions and the basis for a multiyear lighting master plan. Execution of selected tasks will bring FEMP significantly closer to meeting legislative energy savings goals. Recommendations include maintaining an ongoing cognizant FEMP program manager to oversee a core capability in lighting, planning and implementation activities. It will be important to leverage internal and external partnerships to achieve...

CLS creates energy efficient best practice lighting designs for widespread use, and they are made available to users via an interactive webtool that both educates and guides the end user through the application of the Lighting Solutions. This report summarizes the peer review of the beta version of the CLS webtool, which contains retail box lighting solutions.The methodology for the peer review process included data collection (stakeholder input), analysis of the comments, and organization of the input into categories for prioritization of the comments against a set of criteria. Based on this process, recommendations were developed about which feedback should be addressed for the release of version 1.0 of the webtool at the Lightfair conference in New York City in May 2009.Due to the volume of data (~500 comments) the methodology for addressing the peer review comments was central to the success of the ultimate goal of improving the tool. The comments were first imported into a master spreadsheet, and then grouped and organized in several layers. Solutions to each comment were then rated by importance and feasibility to determine the practicality of resolving the concerns of the commenter in the short-term or long-term. The rating system was used as an analytical tool, but the results were viewed thoughtfully to ensure that they were not the sole the factor in determining which comments were recommended for near-term resolution.The report provides a list of the top ten most significant and relevant improvements that will be made within the webtool for version 1.0 as well as appendices containing the short-term priorities in additional detail. Peer review comments that are considered high priority by the reviewers and the CLS team but cannot be completed for Version 1.0 are listed as long-term recommendations.

Executive SummaryProviding high quality and energy efficient lighting in courtrooms is a complex task, and it represents a greater challenge than most other Federal space types. Energy efficient lighting in courtrooms must be accomplished with no sacrifice in quality; efficiency must be effectively invisible to the occupants. The Whole Building Design Guide (WBDG) eloquently states the architectural goals of courthouse design: "As the preeminent symbol of Federal authority in local communities, a Federal courthouse must express solemnity, stability, integrity, rigor and fairness." The courtrooms themselves must have a sense of majesty and be aesthetically inspiring. When paired with the visual needs in a courtroom-given the wide variety of tasks and the critical nature of the courtroom proceedings-one has a challenge indeed.In consideration of these issues, this report reviews existing conditions in courtrooms and provides specific guidance about solutions that will accomplish the dual objectives of high quality and energy efficiency. The material covers all aspects of courtroom lighting, including design criteria, design and application strategies, energy efficient technologies, procurement and team selection, design process and implementation, and education. A detailed energy analysis was performed to develop a baseline for energy consumption in courtroom lighting, and the primary root cause for excessive energy use was found to be a high incidence of incandescent technology. Incandescent lighting was responsible for 54% of the energy consumption but is the least efficient of all the technology options. Point-by-point calculations were completed to provide an energy efficient alternative to the incandescent that met the high level of criteria for performance in courtrooms. Energy modeling was completed based on redesigns that included the use of dedicated compact fluorescent downlights with dimming electronic ballasts and high performance T8 systems, resulting in an average potential savings of 27.6% and 1.2 watts per square foot. A life-cycle cost analysis was performed to provide one example of the type of energy cost savings that is available. The findings showed a Savings-to-Investment Ratio (SIR) of 5.57, and Adjusted Internal Rate of Return (AIRR) of 10.32%, and a simple payback period of four years. The national energy savings potential has been estimated at 13,328,837 kilowatt-hours.Additional detailed design guidance has been provided in the spirit of a holistic solution. It is hoped and anticipated that the recommended solutions will transform courtroom lighting towards both energy efficiency and high quality lighting. This is more important than ever before given the passage of the Energy Policy Act of 2005, which significantly changes the energy usage requirements in Federal buildings. Ultimately it is possible to support the critical and high stakes proceedings in courtrooms while still meeting the civic duty of designing for energy efficiency and sustainability. iv This page is left blank intenti...
