A 10% fuel escalation is considered. 4. A 14% fuel escalation is considered. 5. A 20% fuel escalation is considered. Calculate for 5-, 10-, 15-, 20-year life. Assume straight-line depreciation over useful life, 34% income tax bracket, and no tax credit. Answer Thus, the after-tax savings (AS) are composed of two components. The first component is a uniform series of $660 escalating at e percent/year. 34P/N. Each component is treated individually and converted to present day values using the GPW factor and the USPW factor, respectively.

Most energy audits fall into three categories or types, namely, Walk-Through, Mini-Audit, or MaxiAudit. Walk-ThroughThis type of audit is the least costly and identifies preliminary energy savings. A visual inspection of the facility is made to determine maintenance and operation energy saving opportunities plus collection of information to determine the need for a more detailed analysis. < previous page page_39 next page > < previous page page_40 next page > Page 40 Mini-AuditThis type of audit requires tests and measurements to quantify energy uses and losses and determine the economics for changes.
