BLCC-NIST Building Life-Cycle Cost Program, Version 5.0



S Fuller, A Boyles, Bruce R. Miller


The BLCC5 Building Life-Cycle Cost Program provides economic analysis of projects for which both initial capital costs and future operational costs need to be considered. The program is useful for evaluating the long-term costs and savings of energy and water conservation and renewable energy projects in federal buildings, whether the projects are agency-funded or financed. Economic performance is measured using the American Society for Testing and Material's (ASTM)standard life-cycle cost method combined with the energy conservation criteria required by DOE/FEMP according to 10 CFR 436 and Executive Order 13123. The program calculates Life-Cycle Cost and supplementary measures of cost effectiveness, such as Net Savings, Savings-to-Investment Ratio, Adjusted Internal Rate of Return, and Simple and Discounted Payback Periods. The program also reports annual and life-cycle energy savings and emission reductions for an energy-saving alternative compared wiht a base case.BLCC5 has a windows-based graphical user interface and contains an on-line help manual. It is programmed in JAVA and uses an ml file format.
