Handbook 135 is a guide to understanding the life-cycle cost (LCC) methodology and criteria established by the Federal Energy Management Program (FEMP) for the economic evaluation of energy and water conservation projects and renewable energy projects on all federal buildings. It expands on the life-cycle cost methods and criteria contained in the FEMP rules published in 10 CFR 436, Subpart A, which applies to all federal agencies. The purpose of this Handbook is to facilitate the implementation of the FEMP rules by explaining the LCC method, defining the measures of economic performance used, describing the assumptions and procedures to follow in performing evaluations, giving examples, and noting NIST computer software available for computation and reporting purposes. An annual supplement to Handbook 135, "Energy Price Indices and Discount Factors for LCC Analysis", NISTIR 85-3273-X is also published by NIST to provide the current discount rate and discount factors needed for conducting an LCC analysis in accordance with the FEMP rules. This annual supplement is required when using Handbook 135. This new edition of Handbook 135 replaces the 1987 version. The new edition is extensively revised and organized around the key steps in an LCC analysis. There are no longer separate sections for new and existing buildings and for solar programs, as the methodology no longer distinguishes between these projects.
