Identification ofAnalytical Methods and Tools: The Department seeks input into the selection of engineering and economic analytical tools to be used during the rulemaking (i.e., engineering, national benefits forecast, manufacturer impact, utility impacts, etc.). 9:45

- 11:30 am Engineering Analysis/Data Collection: The Department plans to collect data for the engineering analysis using one or more ofthe following methods: the energy efficiency approach to derive a cost efficiency curve within a range, the design option approach, and the market price (orreverse engineering) approach. The Department will review the key issues surrounding: 1)the pros and cons ofeach approach, and 2)data collection and the reporting ofcosts for incorporation into the engineering analysis.

Good morning, Iam Ed Pollock, Team Leader for the residential central air conditioner and heat pump standards rulemaking team in the Office ofCodes and Standards. The following people are also on the team: Mike Raymond and Carl Adams, from the Office ofCod ;sand Standards; Eugene Margolis from General Counsel; and Mark Friedrichs from the Office ofPolicy and International Affairs. On behalfofthe Department ofEnergy, Iwould like to thank all ofyoufor taking the time to participate in this first public workshop dealing with standards for these products. The purpose ofthis workshop isto discuss the process and analytical toolsto be utilized throughout the central air conditioner/heat pump standards rulemaking process. We plan to provide a more detailed understanding ofthe process and analytical tools to be utilized and receive comments prior to proceeding with data collection and analyses. Today's workshop will focus on the process and analytical tools needed for the engineering/life cycle cost analysis which will part ofthe ANOPR. Aworkshop is planned for April 1999 to discuss the results ofthe engineering/life cycle cost analysis priorto publication ofthe ANOPR. A public notice ofthis workshop today was published inthe Federal Register on May 29, 1998.

### The focus ofthis workshop isfor the Department to listen to comments pertaining to the process and analytical tools to be used. Wewill begin with introductions, then discuss the agenda and expand on the agenda ifnecessary toprovide everyone with an opportunity to discuss their issues. DOE topics will remain on the agenda aslead presentations intheir respective areas. Well take an hour lunch break at a convenient time near 12 noon. Lunch will be
on your own. There isa snack bar on the ground floor almost directly below us. There is the DOE cafeteria on the second floor ofthe west building, and anumber ofrestaurants in the underground mall at L'Enfant Plaza up the street. It will reduce interruptions ifeveryone who wantsto speak waits to be recognized. Please remember to speak into the microphones, especially those inthe audience, and state your name and your company name each time before you speak to assist the court reporter. Side conversations should bekept to a minimum to avoid interrupting the presenter. Since this room isa little crowded today, Iam going to ask you to move tothe lobby area outside ofthisroom orto the hall ifa lengthy private discussion isneeded. It may be necessary to cut offdebate on some topicsto maintain the schedule. There will be time at the end ofthe workshop for additional discussion ofsignificant issues. Iencourage all persons present to participate as much as possible so thatthe Department mayget afull spectrum ofopinion on thesetopics. Thisworkshop isscheduled to end by 4 p.m., or sooner ifall items have been completely discussed. However, Idon't think that will be the case today; we have a pretty full agenda.
