Pie charts similar to Figure 2-8 should be made for each category such as compressed air, steam, electricity, water, and natural gas. Nodal flow diagrams, such as the one in Figure 2-9, illustrate an alternative representation for the steam distribution profile. These diagrams can also assist the auditor in explanation of energy flows and efficiency improvement strategies. INDUSTRIAL AUDIT OPPORTUNITIES Several audits are required to construct the industrial energy use profile. The first two, the Envelope Audit and the Functional Audit are similar to the audits in commercial buildings but the focus of the Energy Accounting and Analysis 33 Figure 2-6.
The sum of all the present values is called the life cycle cost. Two factors enter into appraising the life of the system; namely, the expected physical life and the period of obsolescence. The lesser factor is governing time period. The effect of interest can then be calculated by us- Energy Economic Decision Making 53 ing one of the several formulas which take into account the time value of money. When comparing alternative solutions to a particular problem, the system showing the lowest life cycle cost will usually be the first choice (performance requirements are assess as equal in value).
The alternative with the lowest annual cost is the one to be selected. Step #1 - Determine Present Value P = A × (P/A, I, N) Step #2 - Determine EUAC Using Interest and Lifetime of Measure EUAC = Present Value × (A/P, i, N) Life Cycle Costing A method of evaluating energy conservation options over the life of a system is through life cycle costing. Life cycle costing is used to compare systems over the same lifetime, usually that of the building project. Life cycle costing has brought about a new emphasis on the comprehensive identification of all costs associated with a system.
