# 7­A.1 INTRODUCTION

**Appendix 7­A**  **contains detailed**  **output results**  **from the**  **National Energy** 

**Savings/National Economic**  **Impact spreadsheet**  **model. Results**  **are presented**  **for each** 

**equipment class**  **in terms**  **of cumulative**  **energy savings**  **(source) and**  **cumulative net** 

**present value**  **at each**  **trial standard**  **level and**  **at a**  **national level.** 

**See Chapter**  **7 for**  **an explanation**  **of the**  **figures in**  **this appendix**

VALUE RESULTS CALCULATED FROM THE MARKET BASELINE

**Tables 7­A.1**  **through 7­A.3**  **show the**  **national energy**  **savings and**  **national net**  **present**

**value results**  **from the**  **NIA spreadsheet**  **as calculated**  **above the**  **market baseline.**  **As**

**discussed in**  **chapter 7,**  **the subtraction**  **of the**  **impacts benefits**  **from adoption**  **of standards** 

**consistent with**  **the ASHRAE**  **90.1­2007 levels**  **in 2012**  **(impacts calculated**  **from the** 

**market baseline)**  **from the**  **impacts benefits**  **determined for**  **adoption of**  **higher standards** 

**(also calculated**  **from the**  **market baseline)**  **allows determination**  **of the**  **net impacts**  **for**

**adoption of**  **higher standards**  **when compared**  **with the**  **adoption of**  **standards at**  **the**

**ASHRAE 90.1­2007**  **baseline.**
