Agency Impact Analysis: Life Cycle Costing in the Public Building Service

摘要

The project consisted of the design and implementation of a computer-based life cycle costing model for the long term economic-analysis of space acquisition options. This report reviews the project and discusses the lessons learned and whether further work on the project is justified. The authors find that the model has been most useful in improving the quality of life cycle costing analysis, especially by increasing flexibility with assumptions and providing more capability to examine sensitivity aspects. The model has further potential for assessing costs across and within space alternatives and in evaluating the actual costs of a specific acquisition. These analysis processes will require continual updates and improvements in the data used by the model in order to keep estimates current. Interest in the model continues widely in both the public and private sectors, particularly for the estimation of energy utilization costs.
