There are reliable established guidelines and computer-based tools that effectively support Present Value LCC analyses.
For example, the National Institute of Standards and Technology (NIST) offers NIST Handbook 135 — Life Cycle Costing Manual for the Federal Energy Management Program (PDF 9.7 MB).
NIST annually issues real growth Energy Price Indices and Discount Factors for Life Cycle Cost Analysis as an Annual Supplement to NIST Handbook 135.

- Download the Annual Supplement for 2008 (PDF 1.1 MB).
As a companion product, NIST also offers life cycle cost software with its Building Life Cycle Cost (BLCC) computer program to perform LCC analyses. The latest version of the BLCC program not only structures the analysis, but also includes current energy price indices and discount factor references.
These no-cost NIST materials define all required LCC methodologies used in GSA design applications. We recommend that the building design team obtain the BLCC software and updates from NIST.
When used in conjunction with the ASTM UNIFORMAT II standard, the NIST materials we recommend will result in best-value decisions throughout the entire design process… the perfect complement and answer to the question “What is life cycle costing for construction management?”
