### APPENDIX 11B. NATIONAL EQUIPMENT AND OPERATING COSTS

11B.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 11, 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 = 

# ∑ OCS y 

### × DF y



### PVC = 

# ∑ TIC y 

### × DF y



### 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



### 11B-1

### 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.



### 11B.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

.



### 11B.2.1 Cooking Products

Tables 11B.2.1–11B.2.16 present the national equipment and operating costs, 

### PVC

, 

### PVS

, and 

### NPV for ccoktops and ovens at real discount rates of seven- and three-percent, respectively.



### 11B.2.1.1 Cooktops

Tables 11B.2.1–11B.2.6 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 11B.2.1–11B.2.6 do not vary with the standards case.

Tables 11B.2.1 and 11B.2.2 show the costs, 

### PVC

, 

### PVS , and 

### NPV for electric coil cooktops at real discount rates of seven- and three-percent respectively. Both the candidate standard level (CSL) and trial standard level (TSL) are identified in the following tables.

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.

### 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 11B.2.7–11B.2.14 do not vary with the standards case.

All base case values were determined with shipments projections established under the standards case. As detailed in Chapter 11, 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, the standards case shipments projection and, in turn, the standards case equipment stock, were used to determine the 

### NPV to avoid the inclusion of

### savings due to displaced shipments. Thus, the base case values shown in Tables 11B.2.15 to 11B.2.18 vary with the standards case. Both the CSL and TSL are identified in the following

### 11B.2.2 Commercial Clothes Washers

Tables 11B.2.19–11B.2.22 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.

11B-12

### As detailed in Chapter 11, 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 assumed that any drop in shipments caused by standards would result in the purchase of used machines, 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 11B.2.19 to 11B.2.22 do not vary with the standards case. Both the CSL and TSL are identified in the following tables.
