APPENDIX Q. LIFE-CYCLE COST (LCC) AND PAYBACK PERIOD (PBP) RESULTS Q.1 LIFE-CYCLE COST RESULTS This section provides the frequencyand cumulativedistribution charts of the life-cycle cost (LCC) results for all the efficiency improvement levels analyzed for both product classes of commercial unitary air conditioners: 1) $ 65,000 Btu/h to <135,000 Btu/h and 2) $ 135,000 Btu/h to <240,000 Btu/h. For details on the methodology used to calculate the LCC and payback period (PBP) refer to Chapter 8. The sections that follow present the LCC results from the two approaches used to calculate LCC: 1) a monthly approach establishing annual energy costs using electricity prices determined from electric utility tariffs and 2) an hourly approach establishing annual energy costs using electricity prices that may exist assuming all electricity markets are deregulated. For each efficiency level, frequencyand cumulativecharts are provided showing the distribution of expected LCC differences from the baseline design.Q-2

For details on the methodology used to calculate the LCC and PBP refer to Chapter 8. The sections that follow present the PBP results from the two approaches used to calculate PBP: 1) a monthly approach establishing annual energy costs using electricity prices determined from electric utility tariffs and 2) an hourly approach establishing annual energy costs using electricity prices that may exist assuming all electricity markets are deregulated.
