APPENDIX 8B. LIFE-CYCLE COST AND PAYBACK PERIOD RESULTS

8B.1 DISTRIBUTION OF LIFE-CYCLE COST RESULTS

The distributions presented in this section each correspond to example runs of 10,000 

Monte Carlo samples. As a result, their means may not correspond exactly with the mean values 

presented in the life-cycle cost (LCC) section, which were generated by a different Monte Carlo 

run.
