5­A.1 Introduction
 

Appendix 5­A shows the detailed lifecycle results obtained from running each class of

commercial boiler through the LCC analysis for the AEO 2008 Reference Case fuel price

scenario. The results are shown as distributions of Life Cycle Cost Savings from the Baseline

(ASHRAE 90.1­2007 equivalent) efficiency level for each equipment class. Up to four

efficiency levels above the baseline were analyzed. The results are presented as deciles of

increasing LCC savings in 2008$. Average LCC savings for the distribution as well as the

percent of units experiencing positive LCC savings are shown.

In addition, the distribution of payback periods (PBPs) experienced is also shown. Note that all

paybacks calculated with greater than 100 year PBP were assigned a 100 year PBP. This is done

to avoid as much as possible skewing of the average PBP data to far from the median point, as in

some cases, PBP can be calculated to be essentially infinitely long and averaging these infinite

values is nonsensical in terms of describing the overall results for the population.

5­A.2 LCC Results

Tables 5­A.1 through 5­A.20 shows the distribution of LCC savings and PBP for each of

the 10 classes of commercial boilers analyzed.
