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

7­A.2 NATIONAL ENERGY SAVINGS AND NATIONAL NET PRESENT

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.

VALUE RESULTS GRAPHICS

Figures 7­A.1 through 7­A.92 show the cumulative national energy savings and national

net present value results at both seven percent and three percent discount rates as well as

show the annual operating cost savings and annual equipment costs (shown as negative

savings) for each year from 2012­2085 for each efficiency level treated as a potential

standard level. The results shown here represent the impacts for adoption of boiler

standards higher than the levels specified in ASHRAE 90.1­2007.
