TLCC18 is a life-cycle cost computer program developed at Pacific Northwest Laboratory (PNL). The model is designed to support economic analysis of energy conservation improvements to buildings. The model not only reflects real-world parameters, including utility rates, and tax policies, but also supports economic comparisons between proposed improvements to the building. The task of computing life-cycle costs is not in itself complicated, but complexities are introduced as the modeler attempts to introduce actual utility rate structures, local tax information, multiple fuel inflation rates, and operation, maintenance and capital replacement schedules over the lifetime of the building. TLCC18 captures these complexities to develop realistic life-cycle cost calculation for each case analyzed. The model compares different cases to calculate the internal rate-of-return and the fuel-switching point (among other comparative parameters) to provide the decision maker with information on the relative benefits of different improvements. Volume III is a description of the project's testing process and contains summaries of the energy and economic implications of the application of these recommendations to 10 test buildings across 7 climates. It is supported by appendices that document input data, assumptions, and computer codes employed in the testing process.
