9-iCHAPTER 9. TRIAL STANDARD LEVELS

9.1 INTRODUCTION
DOE generated NES and NPV results based on tr ial standard levels (TSLs). The TSLs are based on the following: (1) candidate standard (efficiency) levels identified in the Advance Notice of Proposed Rulemaking (ANOPR) published in November 15, 2007, 1 (2) the candidate standard level identified with the maximum ef ficiency, and (3) a combination of candidate standard levels for different equipment classes that have potentially positi ve impacts on consumers and the Nation.

This chapter presents information and result s pertaining solely to CCWs. As described in section 1.3 of chapter 1 of this technical s upport document (TSD), DOE is continuing the rulemaking for energy conservation standards fo r microwave oven standby power, and analyses related to these products will be published in a separate TSD. In addition, DOE issued a final rule 2 adopting energy conservation standard s for conventional cooking products ( i.e. , cooktops and ovens) and microwave oven energy factor (EF), and details of the analyses for these products are contained in the co rresponding final rule TSD. 3

9.2 TRIAL STANDARD LEVELS

Table 9.4.1 shows the TSLs for commercial clothes washers. TSLs consist of a combination of modified energy factor (MEF) and water factor (WF). In all, DOE has considered five TSLs. TSL 1 corresponds to th e first candidate standard level from each equipment class and represents the efficiency leve l for each class with the least significant design change. TSL 2 represents the second candidate standard level for front-loading washers while keeping top-loading washers at its first candidate standard level. Over 95 percent of the frontloading washer market either meets or exceeds the second candidate standard level for frontloading washers. In contrast, the second candi date standard level for top-loading washers corresponds to the maximum efficiency level for this class and represents approximately one percent of the top-loading washer market. Th erefore, TSL 2 corresponds to the candidate standard levels for each equipment class that stil l represent a significant share of the market. TSL 3 represents the second candidate standard level for top-loading washers (the maximum efficiency level for this class) while keepi ng front-loading washers at its second candidate standard level. For TSL 3, front -loading washers were held to the second candidate standard level in order to minimize the equipment pri ce difference between the two equipment classes. For TSL 4, top-loading washers are retained attheir maximum efficiency level while frontloading washers are incremented to their thir d candidate standard level. Finally, TSL 5 corresponds to the maximum technologically feas ible level for each equipment class. In progressing from TSL 1 to TSL 5, the LCC sa vings, NES, and NPV all increase. TSL 5 represents the level with the mini mum LCC and maximum NES and NPV.
