Forms Applicable Rule: 60D-4.005, FAC The instructions presented here in Section 2 of Form #AE16(A) pertain to the FLCCA Forms & Documents file. The FLCCA Forms & Documents file is a series of forms that contain: Cover sheet Form #AE16(B) A/E Information Sheet Form #AE16(C) FLCCA Sensitivity Analysis Sheet Form #AE16(D) FLCCA Summary Sheet Form #AE16(E) FLCCA Computation Sheet Form #AE16(F) DOE Forecast Sheet Form #AE16(G) Service Life Sheet This document, Form #AE16(A), should be printed and used as a resource when developing a life-cycle cost analysis for a state agency in Florida. All of the forms listed above that make up the FLCCA Forms & Documents file are available in one Microsoft Excel file from DMS at the following website: 11

13 B. Basic Procedures Applicable Rule: 60D-4.006(5)(c), FAC The FLCCA Forms & Documents file is a spreadsheet-based form available in Microsoft Excel format. The FLCCA Forms & Documents file is an interactive spreadsheet that calculates the total life-cycle cost of alternative designs in accordance with Rule 60D-4.006, FAC. The user of the spreadsheet file will enter the specified project costs in the FLCCA Computation worksheet for each alternative design and the spreadsheet will determine the total life-cycle cost result. All of the project costs required in the FLCCA Computation worksheet shall be developed in accordance with the requirements of Section 2 of Form #AE16(A) this document. The FLCCA Computation worksheet can be copied for each alternative design and renamed by right-clicking on the worksheet tab at the bottom of the screen and selecting MOVE OR COPY, then CREATE A COPY, and then OK. The worksheet tab can then be renamed by double-clicking on the tab name located at the bottom of the screen. The worksheet tab can then be dragged into place immediately after the original FLCCA Computation worksheet. In accordance with Rule 60D-4.004, FAC, the discount rate and future energy price indices are based on predictions by the U.S. Department of Energy (DOE). The procedures outlined in this document also describe procedures to assume incrementally higher discount rates and energy price escalation factors in order to account for economic uncertainty (a.k.a. sensitivity analysis). The life-cycle cost results shall be calculated at DOE conditions and at conditions that assume a higher discount rate and higher future energy prices. Refer to the FLCCA Sensitivity Analysis Sheet section for more detailed information. C. Inflation & Discount Rate The FLCCA Program utilizes a constant dollar approach, meaning that future costs are not calculated with the effects of general price inflation and all future costs are discounted back to present value with a real discount rate. A real discount rate is a discount rate that does not have general price inflation added to it. The result of the constant dollar approach yields the same results as the current dollar approach, which includes general price inflation and utilizes a nominal discount rate (inflation added). The constant dollar approach was chosen because excluding inflation is a simpler approach overall. The discount rate used in the FLCCA Program is the DOE real discount rate found in the Annual Supplement to NIST Handbook 135. D. Submission Requirements Applicable Rules: 60D-4.004, 60D-4.008, FAC A bound copy of the following forms, which are all located in the FLCCA Forms & Documents file, is required for submission to the agency: Cover sheet (8.5 x 11) 12

14 Form #AE16(B) A/E Information Sheet (8.5 x 11) Form #AE16(C) FLCCA Sensitivity Analysis Sheet (8.5 x 11) Form #AE16(D) FLCCA Summary Sheet (8.5 x 11) Form #AE16(E) FLCCA Computation Sheet for each alternative design (11 x 17) The submission shall also include: an electronic version of the FLCCA Forms & Documents file in Microsoft Excel format on an attached compact disk or USB flash drive the input and output reports from the computer-based simulation program (8.5 x 11) Pursuant to Rules 60D-4.004(1) and 60D-4.004(4), FAC, the FLCCA submission shall also be delivered or mailed to the Department of Management Services for an evaluation of life-cycle costs for the following projects: buildings constructed for the use of a state agency additions to existing state-owned buildings guaranteed energy, water, and wastewater performance savings projects as defined in Section , Florida Statutes For renovation projects pursuant to Rule 60D-4.004(2), FAC, the FLCCA submission shall be delivered or mailed to the agency s project director.

The energy price escalation rate and 13

15 discount rate shall be varied in the DOE Forecast worksheet and the total life-cycle cost results of the FLCCA Computation worksheet recorded in this worksheet. For example, increasing the energy price escalation rate by a factor of two is noted as E=2. Likewise, increasing the discount rate to 4% is noted as D=4%. One of the entries shall contain no variance from the DOE energy price forecast and real discount rate. The sensitivity analysis shall vary the discount rate by itself, the energy price forecast by itself and then both variables simultaneously as shown on this worksheet. Analysis of the results shall be discussed in the A/E recommendation on Form #AE16(B). The limits for varying the DOE fuel price indices and discount rate are as follows: The discount rate utilized in the sensitivity analysis shall be raised no higher than twice that of the DOE real discount rate. The energy price projections utilized in the sensitivity analysis shall be no higher than current prices projected at twice the average DOE energy price escalation rate. 2.4 FLCCA Summary Sheet - Form #AE16(D) A.

The residual value shall be derived by linearly prorating the replacement cost based on the ratio of remaining service life to total expected service life, assuming a salvage value of zero. The effects of general price inflation shall be excluded from the residual value. Residual value = replacement cost x (remaining service life / total expected service life) 2.5 FLCCA Computation Sheet Form #AE16(E) Applicable Rules: 60D-4.006(4)(a), 60D-4.006(4)(d), 60D-4.006(4)(e), FAC Use only the green cells to enter data. The FLCCA Computation sheet is a spreadsheet that will automatically discount all future costs to present value, based on the DOE real discount rate located in the DOE Forecast Sheet. The user shall populate this spreadsheet as instructed here. The costs reported here are to be prepared as instructed in the FLCCA Summary Sheet section of this document. The instructions presented in this section apply to all FLCCA Computation spreadsheets. Special note about DOE fuel price indices: The DOE fuel price indices used in the analysis are published by the U.S. Department of Energy each year in April. When the calendar year changes, the user will merely change the actual years on the FLCCA Computation spreadsheet but will continue to use the same DOE projections until the new DOE projections can be adopted into the Florida Administrative Code. A. Enter the alternative design number in cell B-2. B. Enter the analysis period in cell B-3. C. Modify the actual years to begin in the current calendar year if needed in cell B-4. D. Enter the expected ownership costs in the appropriate cells. For non-financed ownership costs, use cell B-8. For financed ownership costs, including guaranteed energy, water, and 19

21 wastewater performance savings projects, enter the required annualized ownership costs as shown in cells B-11 through B-15. All ownership costs shall be the same as the costs reported in the FLCCA Summary worksheet Form #AE16(D). E. Enter the expected annual electrical cost in cell B-26. The expected annual electrical cost shall be the same cost reported in the FLCCA Summary worksheet Form #AE16(D). F. The DOE electrical price indices have been preloaded in cells B-27 through Z-27. The "adjusted" price indices in the DOE Forecast Sheet have been referenced in order to allow for quick sensitivity analysis. For sensitivity analysis, the DOE escalation rate can be modified in the DOE Forecast Sheet and this spreadsheet will automatically calculate the new results. G. Enter the expected annual natural gas cost in cell B-31. The expected annual natural gas cost shall be the same cost reported in the FLCCA Summary worksheet Form #AE16(D). H. The DOE natural gas price indices have been preloaded in cells B-32 through Z-32. The "adjusted" price indices in the DOE Forecast Sheet have been referenced in order to allow for quick sensitivity analysis. For sensitivity analysis, the DOE escalation rate can be modified in the DOE Forecast Sheet and this spreadsheet will automatically calculate the new results. I. Enter the expected cost for other fuels in cell B-36 for other fuels as found in the DOE Forecast Sheet. The expected annual fuel cost shall be the same cost reported in the FLCCA Summary worksheet Form #AE16(D). J. Enter the DOE price indices for other fuels in cells B-37 through Z-37. The user shall reference the appropriate fuel price indices in the DOE Forecast Sheet. The "adjusted" price escalation rates shall be referenced in order to allow for quick sensitivity analysis. By referencing the "adjusted" price escalation factors, rather than entering them one at a time in this spreadsheet, the DOE escalation rate can be modified in the DOE Forecast Sheet and this spreadsheet will automatically calculate the new results. The user must reference the adjusted fuel price indices in the DOE Forecast Sheet. The adjusted fuel price indices in the DOE Forecast Sheet have been highlighted in yellow. K. Enter the assumed water cost escalation rate in cell C-41. This escalation rate shall be based on historical costs for the agency and shall exclude the effects of general price inflation. L. Enter the annual water cost in cell B-42. The expected annual water cost shall be the same cost reported in the FLCCA Summary worksheet Form #AE16(D). M. Enter the expected annual maintenance cost in cell B-52. The expected annual maintenance cost shall be the same cost reported in the FLCCA Summary worksheet Form #AE16(D). N. Enter the expected replacement costs in the years they are expected to occur in cells B-59 through Z-59. The expected replacement costs shall be the same costs reported in the FLCCA Summary worksheet Form #AE16(D). 20

22 O. Enter the expected residual values in the years they are expected to occur in cells B-66 through Z-66. The expected replacement costs shall be the same costs reported in the FLCCA Summary worksheet Form #AE16(D). P. The total life-cycle cost result is calculated in cell B DOE Forecast Sheet Form #AE16(F) Applicable Rule: 60D-4.006(4)(f) This worksheet contains the DOE energy price projections and real discount rate that are incorporated by reference in Rule 60D-4.008, FAC. The FLCCA Computation worksheet references the DOE information on this worksheet. This worksheet is also where the user will change the discount rate and energy escalation rate to perform the sensitivity analysis. 2.7 Service Life Sheet Form #AE16(G) This worksheet contains the ASHRAE equipment service life estimates that are incorporated by reference in Rule 60D-4.008, FAC. This worksheet has been provided as a reference for the user when replacement costs have to be considered. Refer to Capital Cost Information in the FLCCA Summary Sheet section of this document for more detailed information. END OF DOCUMENT 21
