## 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.**
