A.1 INTRODUCTION

This appendix presents instructions for us ing the engineering anal ysis spreadsheet for beverage vending machines.

The engineering analysis spreadsheet details the assumptions, methodology, and calculation of cost-efficiency curves using a desi gn-option approach (chapt er 5 of this TSD for more information on this approach). It was deve loped using Microsoft Excel, which is a general spreadsheet application and is known to most stak eholders. In addition, th e engineering analysis spreadsheet is designed to be stand-alone, a nd has been thoroughly documented. This Appendix serves as additional guidance on how to navigate , use, and understand the engineering analysis spreadsheet.

A.2 USING THE ENGINEERING ANALYSIS SPREADSHEET

The content of the spreadsheet is co ntained on eight primary worksheets:

 Start Here – General information on how to navigate the spreadsheet.

 Introduction – Overview of the spreadsheet.

 Results – DOE’s cost-efficiency results.

 Calculation – Detailed calculations of energy consumption and cost.

 Equipment Classes – Description of covered equipment classes.

 Assumptions – List of numerical and non- numerical assumptions used.

 Model – Description of the en ergy-consumption model.

 Design Options – Description of design options.

A.2.1 Start Here Worksheet

When the spreadsheet is opened, the Star t Here worksheet will be displayed (see Figure A.2.1). The eight primary worksheets are limited in width in order to fit comfortably on all monitors. Scrolling down may be necessary to see all content. Each primary worksheet has an “END OF PAGE” footer to in dicate the end of content. This worksheet contains a legend that describes the formatting used throughout the spreadsheet. This formatting is intended to highlight different types of information and areas of user input ( e.g. , yellow boxes are used to highlight important information and green boxes with dash ed gray borders accept user input). The Start Here worksheet also contains navigation links to the other main worksheets, which are duplicated on each of the primary sheets for navigation.

A.2.2 Introduction Worksheet

The Introduction worksheet provides genera l background information on the beverage vending machine rulemaking and a brief descri ption of each of the other primary content worksheets

A-2 BVM_FINAL_FR_TSD_AppendixA_08-14-09.doc(

Figure A.2.2). Additionally, a link is provide d to the online TSD for reference. The buttons before each worksheet description can be used to go to those worksheets.

A-3 BVM_FINAL_FR_TSD_AppendixA_08-14-09.docFigure A.2.2 Screen Shot of the Introduction Worksheet (not all content shown)

A.2.3 Results Worksheet

The Results worksheet provides pl ots and tables of cost-efficiency results for each of the equipment classes DOE examined (

Figure A.2.3). The top portion of the worksheet contains a button that activates a pop-up window for selecting an equipment class, as well as several user-selectable options for displaying different information about that class. The “E quipment Class Selection” menu appears when the “Change Equipment Class” button is clicked, and a llows the user to select the equipment class and machine size using the appropriate option buttons. Displayed below the button are the equipment class description and ta bulated cost-efficiency data fo r both the analytically derived DOE curve and the user-defined curve. Below that information is a cost-efficiency plot with the appropriate curves.

A-5 BVM_FINAL_FR_TSD_AppendixA_08-14-09.docFigure A. 2.3 Screen Shot of Results Worksheet (continued)

The tabulated cost-efficiency data can be displayed without normalization, or be normalized by refrigerated volume (V). Use the “D ata Normalization” option buttons in the top right of the screen to select.

To view or modify equipment design speci fications, press the “V iew/Change Design Specifications” button located in th e upper section of the worksheet. This button takes the user to the “Design Specifications” sheet (Figure A.2.4), which contains the DOE specifications, as well as a column to input user-defined specifications. Initially, user design spec ifications are identical to DOE design specifications. However, any change s made to the spreadsheet will be stored, meaning that if the spreadsheet is saved, any changes to user-defined design specifications will be saved as well. The user may change the us er design specification values by entering new values in the “User” column, and then clicking the “Save and Return to Results” button. Clicking the “Save and Return to Results” button will return the user to the results sheet and instantly update the user-defined results ta bles with the results from the user-input values. The “Set to DOE Default Specifications” button will reset th e user-defined values to the default DOE specifications. Press the “Cancel” button to cancel any changes and return to the Results sheet.

A-6 BVM_FINAL_FR_TSD_AppendixA_08-14-09.docFigure A.2.4 Screen Shot of Design Specifications Worksheet

The “View/Change Design Options” button in the upper middle portion of the page takes the user to the “Design Option Order” sheet, which contains a design options selection matrix ( Figure A.2.5). Use this design option selecti on matrix to change the baseline design options and implementation order of design optio ns for the current equipment class. Design options not applicable to the current equipm ent class are hashed gray, and design options changed from the previous level are highlighted in yellow. Using the in-cell drop-down menus, select baseline design options, then select one or more design option changes for each level above the baseline, up to 15 leve ls. If there are fewer than 15 design option changes, fill the remaining levels with the last configuration. To order design op tions automatically by payback period (shortest to longest), pre ss the “Auto-Sort Design Options” button after selecting baseline design options. To compare to the order DOE us ed (where applicable), press the “View DOE Design Option Order” button, and a pop-up window c ontaining a design options selection matrix (similar to the one seen in Figure A.2.5) with the design option order used by DOE will be displayed. To return the design opt ion matrix to the default DOE values (where applicable), press the “Set to DOE Design Option Order” button. When complete, pr ess the “Save and Return to Results” button to return to the Results work sheet. Press the “Cancel ” button to cancel any changes and return to the Results sheet.

A.2.4 Calculation Worksheet

The Calculation worksheet shows detailed calculations of energy consumption and cost for the current equipment class (

Figure A. 2.6 ). To select an equipment class, cl ick the “Change Equipment Class” button in the upper left of the work sheet, and on the pop up menu choose the equipment class and machine size using the appropriate option buttons. The Calculation worksheet presents two sets of calculations: one using DOE’s default values and one using user-input values. Switch between the two with the “Display” option buttons. The cost-efficiency data are calculated using the equipment design specifications, design options , and assumptions determined by DOE. Case design specifications are presente d, followed by a matrix of design options used in the model and energy consumption and cost calculations. Each row in the calculation tables represents a different step in the calculation of cost or energy consumption. Each column represents a different design option level, from baseline up to the maximum technology level (max tech). Columns above the max tech level repeat the ma x tech configuration and are grayed out. View the Model sheet for a schematic representation of the model linked to sp ecific calculations.

A.2.5 Equipment Classes Worksheet

The Equipment Classes worksheet contains in formation on the equipment classes covered by this rulemaking. Details of equipment class or ganization are presented in chapter 3 of this TSD. To view the results or modify the inputs fo r either equipment class, follow the link for that equipment class under the “Results Link” column.

A.2.6 Assumptions Worksheet

The Assumptions worksheet lists non-numer ical assumptions as well as numerical assumptions and engineering constants used in the calculation of cost -efficiency data. Nonnumerical assumptions include general assump tions about the analysis and design options. Numerical assumptions include c onstants and other parameters us ed in the calculation of energy use. All sources of information are documen ted in Chapter 5 of this TSD. Additional assumptions can be found for specific design op tions on their respectiv e sheets (see section A.2.8). The user can alter the numerical assumptions, which will immediately be reflected in the tabulated cost-efficiency data in the Results worksheet.

A-9 BVM_FINAL_FR_TSD_AppendixA_08-14-09.docA.2.7 Model Worksheet

The Model worksheet contains a diagram of the energy consumption model used in the engineering analysis. Details of th is model are presented in chapter 5 of this TSD. Click any part of the model to be taken to th e corresponding calculation in the Ca lculation worksheet. The user can return to the Model worksheet using the navi gation links that are loca ted at the top of each sheet.

A.2.8 Design Options Worksheet

The Design Options worksheet lists the de sign options used in constructing costefficiency curves. Each design option is give n an index number and a corresponding worksheet (numbered 1.0 to 20.0) where detailed information is contained. Although the spreadsheet has room to describe 20 design options, only 13 desi gn options are currently employed in the model (see chapters 4 and 5 of this TSD). Each de sign option has two to th ree levels, ranked by performance from lowest to highest. Each level is given a lettering code that is used to identify it in the design options matrix for each equipment class. Links are provided to the individual numbered worksheets, where detailed information is contained a bout the design options. Additional information is also prov ided in chapter 5 of the TSD.

A.2.9 Supporting Worksheets

Several supporting worksheets are used in the spreadsheet in addition to the eight primary content worksheets. Some of these contain consta nts or other information not necessary for user interaction and are hidden from view. Those that are visible (the numbered design options worksheets) are accessible using the links provided on the primary worksheets when the information on the supporting worksheets is re levant (see sections A.2.3, A.2.4, and A.2.7).
