2 1. GETTING STARTED The current version of the Compressed Air Savings Calculator can be downloaded from It is included in the Smart $aver Custom-To-Go tool suite, which contains a number of useful tools that can help you calculate savings and incentives for various energy saving measures. The ZIP output file from the calculator must be submitted with the Smart $aver application (Step 1) in order to receive an incentive payment. For application submissions and questions about the application process, contact us at CustomIncentives@dukeenergy.com. 2. MEASURE TOOL DESCRIPTION Compressed air systems provide power for tools, presses, controls and a wide variety of industrial equipment and processes. As such, compressed air systems vary widely both in the equipment and controls that are employed. Compressed air systems afford significant opportunities for energy savings and the Duke program has provided incentives for equipment and control upgrades since the program s inception. The Compressed Air Savings Calculator draws extensively from information provided by the Department of Energy (DOE) Compressed Air Challenge program. Specifically, the AirMaster+ software package developed by DOE is used as a guide for generic equipment performance characteristics and operating ranges covered by the Compressed Air Savings Calculator. The Compressed Air Savings Calculator provides for the following compressed air system measures: Direct replacement of one to five air compressors, including compressors equipped with variable speed drives, Installation or upgrade of system storage, Installation of intermediate pressure/flow control valves, and Reconfiguration of air inlet to outside air. The Compressed Air Savings Calculator allows implementation of any of these measures as retrofit projects that do not involve any increase in load (deferred load). Note that in the case of new installations the lack of operating data restricts the complexity of the savings analysis and limits the types of energy efficient measures that can be accommodated. Therefore, for applications involving new installations the Compressed Air Savings Calculator will only accommodate measures involving efficient compressor installations (increased storage, intermediate pressure controls and reconfiguration of inlet air are not accommodated). Version /1/2015 Page 2 of 55

3 2.1. Appropriate Use of the Tool The Compressed Air Savings Calculator can be used for compressed air systems and measures having the characteristics shown in Table Applicable Types of Equipment The Compressed Air Savings Calculator covers the same compressor types and pressure ranges that are covered by the AirMaster+ software package as shown in Table Equipment Sizes or Capacities Covered by the Tool The Compressed Air Savings Calculator covers the same compressor types and pressure ranges that are covered by the AirMaster+ software package (also shown in Table 2). Description # of Compressors 1 5 Compressor types and sizes Compressor drive Storage Intermediate Flow / Pressure Controller Reconfiguration of inlet air to Outside Air Baseline air compressor efficiency Compressor Load Profile Applicable operating pressure range Table 1: Air Compressor Common Measure Features Measure Feature Single and dual stage reciprocating, oil-flooded and oil-free rotary screw and centrifugal type air compressors Conventional and Variable Speed Drive (VSD) Existing or new storage will be accommodated but only storage located upstream of an installed intermediate flow/pressure control will be used to analyze compressor operation. This measure is not supported for deferred load or new installations. The addition of an intermediate flow/pressure controller is supported as an efficiency measure only (baseline system doesn t include this option). This measure is not supported for deferred load or new installations. The addition of plumbing and filtration (if needed) to bring inlet air from the outside instead of from the compressor room is an efficiency measure. This measure is not supported for deferred load or new installations. Generic compressor efficiencies used in AirMaster+ software package are used as minimum acceptable efficiency for the types and sizes of compressors identified by the project sponsor. Hourly load profile inputs (acfm or kw) used for up to 4 day types to establish baseline usage of each compressor and for overall system load. Systems less than 100 HP can use generic load profiles. Pressure range varies with compressor type as per AirMaster+ Page 3 of 55 Version /1/2015

18 3.5. Error Messages and Notes While using the Compressed Air Savings Calculator, you may see one of the following error messages: This message indicates that you have not made a selection or entered an appropriate value in one or more required fields. Please review your inputs and make sure that you have entered appropriate values in the indicated input fields. This message indicates that the proposed retrofit qualifies for incentives through the prescriptive incentives program. Measures that qualify for the prescriptive program cannot apply for incentive through the custom incentives program (Classic Custom or Custom-To-Go). Version /1/2015 Page 18 of 55

19 This message indicates that the proposed compressed air retrofit does not have enough capacity to meet the system demand as outlined in the operating profile. Measures that experience this error message will require adjustments to either the operating profile data or the proposed compressed air system capacity. This message indicates that the proposed project exceeds the upper limit of the Custom- To-Go program and is only eligible for incentives through the Classis Custom program. Please submit an applition to the Classic Custom program for this project. This message indicates that your compressed air project will result in negative savings and incentives. Please review your measure inputs and ensure that all inputs are correct. You will not be able to generate a report for a project that has negative savings. Page 19 of 55 Version /1/2015
