APPENDIX 10B. NATIONAL EQUIPMENT AND OPERATING COSTS 

10B.1 INTRODUCTION 

In this appendix, the Department presents the components of the net present value (NPV), 

namely, the present value of the equipment (or total installed costs) and the present value of the 

operating costs for each of the four appliance products. The present value of equipment costs is 

also termed the cumulative national equipment costs while the present value of operating costs is 

also termed the cumulative national operating costs. 

As presented in Chapter 10, National Impact Analysis, the NPV is described by the 

equation: 

NPV = PVS _ PVC 

where: 

PVS = Present value of operating cost savings (including energy, water, repair, and 

maintenance costs) and 

PVC = Present value of increased total installed costs (including equipment and 

installation). 

The PVS and PVC are determined according to the following expressions: 

PVS = ∑OCSy × DFy 

PVC = ∑TICy × DFy 

where: 

OCS = Total annual operating cost savings each year summed over vintages of the 

product stock, 

TIC = Total annual installed cost increases each year summed over vintages of the 

product stock, 

DF = Discount factor in each year, and 

y = Year in the forecast (i.e., 2012 to 2042). 

PVS and PVC are determined for each year from the effective date of the standard to the year 

when units purchased in 2042 retire. 

The present value of operating costs and the present value of equipment costs (or total 

installed costs) are the components comprising the PVS and PVC, respectively. The PVS is 

10B-1

EE-2006-STD-0127 COMMENT 39.2
determined by taking the difference between the present value of operating costs for the base 

case and the present value of operating costs for the standards case. The PVC is determined by 

taking the difference between the present value of equipment costs for the base case and the 

present value of equipment costs for the standards case. 

10B.2 RESULTS 

For following sections provide tables showing the present value of operating costs (also 

known as the cumulative national operating costs) and the present value of equipment costs (also 

known as the cumulative national equipment costs) each of the four appliance products. For 

each product, two sets of results are presented; one based on a seven-percent and another based 

on a three-percent discount rate. 

In the tables provided in the following sections, the national operating and equipment 

costs are presented for the base case (i.e., without standards) and each standard level analyzed. 

Differences between the base case and standards cases are also presented. The difference in the 

national equipment costs represents the PVC or present value of equipment cost increases while 

the difference in the national operating costs represents the PVS or present value of operating 

cost savings. The difference between the base case and standards case total national equipment 

and operating costs represents the NPV. 

10B.2.1 Dishwashers 

Tables 10B.2.1 and 10B.2.2 present the national equipment and operating costs, PVC, 

PVS, and NPV for standard-sized dishwashers at real discount rates of seven- and three-percent, 

respectively. 

As detailed in Chapter 9, shipments projections under the standards cases were 

determined to be lower than those in the base case projection due to the higher installed cost of 

the more efficient equipment. Typically, DOE would use the standards case shipments 

projection and, in turn, the standards case equipment stock, to determine the NPV to avoid the 

inclusion of savings due to displaced shipments. But because DOE explicitly accounted for the 

energy and water consumption of the displaced shipments, DOE maintained the use of the base 

case shipments to determine the annual energy consumption in the base case. Thus, the base 

case values shown in Tables 10B.2.1 and 10B.2.2 do not vary with the standards case.

10B.2.2 Dehumidifiers 

Tables 10B.2.3 and 10B.2.4 present the national equipment and operating costs, PVC, 

PVS, and NPV for dehumidifiers at real discount rates of seven- and three-percent, respectively. 

Each table shows the costs, PVC, PVS, and NPV for each of the six product classes as well as the 

totals for all products classes. 

All base case values were determined with shipments projections established under the 

standards case. As detailed in Chapter 9, shipments projections under the standards cases were 

determined to be lower than those in the base case projection due to the higher installed cost of 

the more efficient equipment. As a result, DOE used the standards case shipments projection 

and, in turn, the standards case equipment stock, to determine the NPV to avoid the inclusion of 

savings due to displaced shipments. Thus, the base case values shown in Tables 10B.2.3 and 

10B.2.4 vary with the standards case.

Tables 10B.2.5–10B.2.20 present the national equipment and operating costs, PVC, PVS, 

and NPV for cooking products at real discount rates of seven- and three-percent, respectively. 

10B.2.3.1 Cooktops 

Tables 10B.2.5–10B.2.10 present the national equipment and operating costs, PVC, PVS, 

and NPV for cooktops. In the case of electric and gas cooktops, because the housing market is 

fully saturated (i.e., all households have cooktops either in the form of ranges or stand-alone 

units), DOE assumed that standards would neither impact shipments nor cause shifts in electric 

and gas cooktop market shares. Therefore, DOE’s standards case shipments for electric and gas 

cooktops were identical to its base case shipments. Typically, DOE would use the standards case 

shipments projection and, in turn, the standards case equipment stock, to determine the NPV to 

avoid the inclusion of savings due to displaced shipments. But because DOE assumed no drop in 

shipments due to standards, DOE maintained the use of the base case shipments to determine the 

annual energy consumption in the base case. Thus, the base case values shown in Tables 

10B.2.5–10B.2.10 do not vary with the standards case. 

Tables 10B.2.5 and 10B.2.6 show the costs, PVC, PVS, and NPV for electric coil

10B.2.3.2 Ovens 

Tables 10B.2.11–10B.2.18 present the national equipment and operating costs, PVC, 

PVS, and NPV for ovens. In the case of electric and gas ovens, because the housing market is 

fully saturated (i.e., all households have ovens either in the form of ranges or stand-alone units), 

DOE assumed that standards would neither impact shipments nor cause shifts in electric and gas 

oven market shares. Therefore, DOE’s standards case shipments for electric and gas ovens were 

identical to its base case shipments. Typically, DOE would use the standards case shipments 

projection and, in turn, the standards case equipment stock, to determine the NPV to avoid the 

inclusion of savings due to displaced shipments. But because DOE assumed no drop in 

shipments due to standards, DOE maintained the use of the base case shipments to determine the 

annual energy consumption in the base case. Thus, the base case values shown in Tables 

10B.2.11–10B.2.18 do not vary with the standards case. 

Tables 10B.2.11 and 10B.2.12 show the costs, PVC, PVS, and NPV for electric standard 

ovens at real discount rates of seven- and three-percent respectively.

All base case values were determined with shipments projections established under the

determined to be lower than those in the base case projection due to the higher installed cost of 

the more efficient equipment. As a result, the standards case shipments projection and, in turn, 

the standards case equipment stock, were used to determine the NPV to avoid the inclusion of
