# 9 Purpose of Workshop: The objective ofthe workshop istodiscuss the process and analytical methodologies to be used in a rulemaking to revise the current energy conservation standards forcentral air conditioners. 

### Expected Outcome ofWorkshop: To identify the process and thetools to be used forthe central air conditioner rulemaking. PreliminaryAgenda 9:00

- 9:15 am Opening Remarks, Introductions, Agenda Review 9:15

- 9:45 am Overview ofthe Preliminary CentralAir Conditioner Rulemaking Schedule Review ofthe Rulemaking Framework: The Department will seek comment on the draft analytical framework for the central air conditioner rulemaking. 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 (or reverse 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. 

### 11:30

- 12 noon Costs/Prices: The Department will lead a discussion on possible approaches to generating retail prices to be used in the consumer life-cycle-cost analysis. Components include manufacturing costs, distribution and installation costs, and markups. 12 noon - 1:00 pm Lunch (on your own).

### 1:00

- 2:15 pm Life-Cycle-Cost: The Department plans to demonstrate a new life-cycle-cost spreadsheet model which can account for variability ofkey criteria, such as utility rates and climate, and the effects ofthese variations on different consumers. 2:15

- 2:45 pm Energy Savings Forecasts: The Department will present an example ofenergy savings forecasting results using a simple spreadsheet to show how the growth in efficiency can be accounted for over time. 2:45 - 3:00 pm Break 3:00

- 3:30 pm Refrigerant and Other Engineering Issues: The refrigerant used inair conditioners will be banned by the EPA in 2010. The Department will lead a discussion on the effects ofthisban on thetiming ofthe revision to central air conditioner standards. 3:30

- 4:00 pm Next Steps: Issues to be resolved, stakeholders concerns, and any follow-up workshops. Closing Remarks
