5B-i______________________________________________________________________________ APPENDIX 5B. MANUFACTURER INTERVIEW GUIDES

5B.1 INTRODUCTION This appendix presents samples of the interview guides used during the manufacturer interviews. The interview guides detail the questi ons DOE used as the basis for the discussions with manufacturers of residential dishwash ers and dehumidifiers, and commercial clothes washers. The results of the manufacturer interv iews were aggregated a nd incorporated into the engineering analysis (see Chapter 5 of the TS D) and the preliminary manufacturer impact analysis (see Chapter 12 of the TSD).

5B.2 DISHWASHER MANUFACT URER INTERVIEW GUIDE The following questions comprised the inte rview guide DOE used while interviewing dishwasher manufacturers.
