William K., I'm with you.  Require motor companies to publish efficiencies and clearly label them on the motor nameplate; let the market drive the need.

Excellent information John.  I just hope the DOE continues to include industry when determining development to standards or altering existing standards.  I would hope also all efforts include looking at existing standards and methodology for developing standards relative to global sales and marketing.  If we can develop products that can be used in Western Europe and possibly the Far East "up front" we will be money ahead in the long run.  I retired from a company that made considerable efforts to adapt products designed for US markets to European markets.  In the long run, the efforts provide products that simply did not compete.

While improving efficiency is a valid target, the creation of rules will undoubtedly lead to problems because firm rules seldom are able to cover all conditions. So instead, how about just creating a uniform standard for measuring and reporting efficiency and not making so many rules. In some instances efficiency is far from the most important consideration, seldom used emergency equipment and systems being one example.

Thanks for your comment.

DOE is working with the fan group on how they will test. They only want to cover the fan and not a complete system. The proposal is to use a motor with an efficiency as high or higher then the original that was certified with the fan as static pressure changes and larger motors are needed.

For pumps, the group is looking at a similar EU regulation and test methods set up by the Europump organization which takes all components into consideration making it closer to a plug to water efficiency.

These proposals will be studied by DOE and their technical partners at Lawrence Berkely Labs. There will be chance for public comment during the rulemaking process.

John, as of now energy auditing & testing bureau are offering various star rating to the devices based on certain parameters. In general it depends up on energy consumption and efficiency. But how the new system is going to define these parameters?
