DEPARTMENT OF ENERGY

CENTRAL AIR CONDITIONER STANDARDS WORKSHOP

June 30, 1998

U.S. Department of Energy

1000 Independence Avenue, S.W. Room tE-9 8 g 0 9

Purpose of Workshop: The objective of the workshop is to discuss the process and analytical

methodologies to be used in a rulemaking to revise the current

energy conservation standards for central air conditioners.

Expected Outcome of Workshop: To identify the process and the tools to be used for the central air

conditioner rulemaking.

Preliminary Agenda

9:00 - 9:15 am Opening Remarks, Introductions, Agenda Review

9:15 - 9:45 am Overview of the Preliminary Central Air Conditioner Rulemaking Schedule

Review of the Rulemaking Framework: The Department will seek comment on the draft analytical

framework for the central air conditioner rulemaking.

Identification of Analytical 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 of the 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 of each

approach, and 2) data collection and the reporting of costs 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).

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 of key criteria, such as utility

rates and climate, and the effects of these variations on different consumers.

2:15 - 2:45 pm Energy Savings Forecasts: The Department will present an example of energy

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 in air

conditioners will be banned by the EPA in 2010. The Department will lead a

discussion on the effects of this ban on the timing of the revision to central air

conditioner standards.

3:30 - 4:00 pm Next Steps: Issues to be resolved, stakeholders concerns, and any follow-up

workshops.
