APPENDIX 10B. SUPPLEMENTARY SCENARIOS FOR THE NATIONAL IMPACTS

ANALYSIS

10B.1 INTRODUCTION

In this appendix, DOE presents inputs and results for two additional IRL sensitivities.

DOE presents the efficacy forecast, lamp stock, lumen output, NES and NPV results for the IRL

65W BR lamp substitution sensitivity and for the IRL 10 percent lumen increase sensitivity.

10B.2 STANDARDS CASE EFFICACY FORECAST, LAMP STOCK AND LUMEN

OUTPUT

A key aspect of DOE’s estimates of NES and NPV is the proportions of future lamp

shipments meeting different efficacies for the base case (without new standards) and each of the

standards cases (with new standards). Because key inputs to the calculation of the NES and

NPV are dependent on the estimate of the efficacies shipped and efficacies in the stock, it is

important to know the projected efficacy­distribution of lamp shipments. Table 10B.2.1 presents

the efficacy distribution of lamp shipments for commercial IRL under the 65W BR lamp

substitution sensitivity.

The calculation of the NES and NPV is dependent on the estimate of the average efficacy

in the lamp stock. The following figures present the average efficacy of the IRL stock for each

CSL under the two sensitivity scenarios. The average efficacy numbers do not include stock

moving to reflector CFL or other emerging technologies overtime. Figure 10B.2.1 and Figure

10B.2.2 present the base case and standards case average efficacy forecasts of IRL in the

commercial and residential sectors, respectively, from 2012 to 2042 under the 65W BR lamp

substitution sensitivity. Though 65W BR30 and BR40 lamps are not considered to be covered

IRL product, the average efficacy forecasts below include both covered IRL product and lowerefficacy incandescent 65W BR30 lamp.

Changes in efficacy can lead to changes in lumen output. For IRL, the average lumen output

numbers do not include stock moving to reflector CFL or other emerging technologies overtime.

commercial IRL stock under the 65W BR lamp substitution sensitivity from 2012 to 2042.

10B.3 NATIONAL ENERGY SAVINGS AND NET PRESENT VALUE RESULTS

The following tables provide NES results for each CSL considered for incandescent

reflector lamps under the 65W BR lamp substitution and 10 percent lumen increase sensitivities.

Results are cumulative to 2042 and are shown as primary energy savings in units of quads. In

general, both of these sensitivity scenarios reflect lower energy savings than the main shipment

scenario, as both sensitivities incorporate higher­wattage or same­wattage lamp designs. In

contrast, the main shipment scenario utilizes reduced­wattage lamp designs.
