PURPOSE AND EFFECT: Amends the current Rule to comply with Sections 255.251, 255.252, 255.253, 255.254, 255.255 and 255.256, Florida Statutes (The Florida Energy Conservation and Sustainable Buildings Act of 2008). The effect of the proposed Rule will be uniform agency procedures regarding the selection of energy-consuming equipment and architectural components for new state-financed facilities and existing state-owned facilities.
SUMMARY: The proposed amendment is a substantial revision to the existing Rule. The proposed amendment includes energy performance standards based on sustainable building ratings, requirements for the evaluation of alternative architectural and engineering designs, and procedures for conducting a life-cycle cost analysis of the required alternative designs. The proposed Rule also incorporates a new program titled the “Florida Life-Cycle Cost Analysis Program” that documents compliance with the proposed Rule when a life-cycle cost analysis is required. The Division of Real Estate Development and Management has consulted with the Florida Small Business Regulatory Advisory Council and has determined that this amendment has no negative impact on small businesses as defined by Section 288.703, F.S., nor on small counties or small cities as defined by Section 120.52, F.S., since the added engineering design costs will be assumed by state agencies.
SUMMARY OF STATEMENT OF ESTIMATED REGULATORY COSTS: No Statement of Estimated Regulatory Cost was prepared.
Any person who wishes to provide information regarding a statement of estimated regulatory costs, or provide a proposal for a lower cost regulatory alternative must do so in writing within 21 days of this notice.

1. The analysis shall include the replacement cost for new energy-consuming equipment that has an expected service life that is shorter than the analysis period.
2. Expected service life:
a. The expected service life utilized in the analysis for energy-consuming equipment shall be based on the 2007 ASHRAE Handbook – HVAC Applications (Chapter 36, Table 4), which is incorporated by reference in Rule 60D-4.008, F.A.C., but may be modified to account for the following circumstances:
(1) The agency’s experience with similar equipment
(2) Harsh environments such as coastal, marine, industrial, and urban areas that can effectively shorten equipment service life
b. For equipment not included in the 2007 ASHRAE Handbook – HVAC Applications (Chapter 36, Table 4) per paragraph (a) of this section, the expected service shall be estimated based on one or both of the following criteria:
(1) The equipment manufacturer’s recommendation
(2) The judgement of a licensed architect, engineer, or contractor
3. Replacement costs shall be derived from the initial ownership costs.
4. The DOE real discount rate shall be used to convert all future replacement costs to present value dollars. The DOE real discount rate is available in the Annual Supplement to NIST 135, which is incorporated by reference in Rule 60D-4.008, F.A.C.
5. The effects of general price inflation shall be excluded from the analysis.
6. The life-cycle replacement cost shall be calculated as the sum of all present-value replacement costs that are expected to occur during the analysis period.
(e) Residual value:
1. The analysis shall include residual value for energy-consuming equipment that is expected to be replaced during the analysis period and therefore has an expected service life that extends beyond the analysis period.
2. 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.
3. The DOE real discount rate shall be used to convert all residual values to present value dollars. The DOE real discount rate is available in the Annual Supplement to NIST 135, which is incorporated by reference in Rule 60D-4.008, F.A.C.
4. The effects of general price inflation shall be excluded from the analysis.
(f) Total life-cycle cost: The total life-cycle cost shall be calculated as follows:
1. The life-cycle ownership cost, plus;
2. The life-cycle operating cost, plus;
3. The life-cycle maintenance cost, plus;
4. The life-cycle replacement cost (when applicable), less;
5. The residual value (when applicable).
(g) Sensitivity analysis:
1. The agency shall perform a sensitivity analysis as described in this section to account for uncertainty in the discount rate and future energy prices in an attempt to ascertain which variable(s) are most critical to the financial performance of the project.
2. The sensitivity analysis shall be structured to determine the total life-cycle cost result as a result of incrementally modifying the discount rate and energy price projections one at a time, and then both simultaneously.
3. Limits:
a. The discount rate utilized in the sensitivity analysis shall be raised no higher than twice that of the DOE real discount rate.
b. The energy price projections utilized in the sensitivity analysis shall be raised no higher than current prices projected forward at twice the average DOE price escalation rate.
(5) Submission requirements:
(a) The life-cycle cost analysis shall be submitted to the agency during the design development phase of the project.
(b) The life-cycle cost analysis shall be submitted to the department in addition to the agency for projects that pertain to subsections 60D-4.004(1) and 60D-4.004(4), F.A.C., during the design development phase of the project, pursuant to Sections 255.254(1) and 489.145(6), Florida Statutes.

(3) Energy performance analysis:
(a) Energy Star rating:
1. An Energy Star rating shall be developed with the Energy Star Portfolio Manager or Energy Star Target Finder program along with actual utility bill data for the previous twelve months.
