ENERGY DESCRIPTOR/TEST PROCEDURE WORKSHOP AGENDA OUTLINE

8:30 Registration & Coffee

8:45 Introductory Remarks

9:00 Session 1: Energy Efficiency Descriptors

* Briefing on the current Furnace Test Procedure

* Briefing on the history and intent of the F-factor

* Possible discussion items:

- To what extent do the efficiency descriptors not account for the total energy consumption of

appliances?

Do consumers have adequate means to calculate the annual operating cost of appliances

using current descriptors?

- Is there a marketplace need for new descriptors?

- Statutory and marketplace limitations on descriptors which DOE can prescribe.

- Use of separate or combined energy descriptors for each energy source used by an appliance

11:00 Session 2: Multi-Function Appliances

* Summary of Carrier and Nordyne waivers

* Briefing on the testing NIST has performed on multi-function equipment

* Possible discussion items:

- Is there a need to develop a simple way to combine the ratings for different functions of

combined products in such a way that they can be compared to single function products?

- Identify all types of multi-function residential HVAC appliances now in the marketplace and

how the energy efficiency of each appliance type is currently being described.

- Status and scope of ASHRAE standard 137 (Methods of Testing for Efficiency of Spaceconditioning/Water-heating Appliances that Include a Desuperheater Water-heater)

- Status and scope of ARI standard (Air Conditioning and Heat Pump Equipment

Incorporating Potable Water-heating Devices)

DOE's plans regarding ASHRAE standard 124 (Method of Testing for Rating Combination

Space-heating and Water-heating Appliances)

Use of separate descriptors for each energy source used by an appliance

- Would consumers have adequate means to calculate annual operating costs?

12:00 Lunch
