I'm having a little confusion as to what "Rated Power" means. up until now I have been listing the rated power as the energy usuage at maximum operation. Then I stumbled onto a spec like this:
http://www.chainc.com/filearchive/ap4500specs.pdf
where the power consumption is listed at 1000W but the "energy star mode" is listed at 45W. Which number do I use?

Kelvin,
That's a difficult situation. To claim the 45W of the "Energy Star Mode" you need to provide some claim that the end-user will use the copier in that mode. If you provide some kind of narrative explaining how and why the copier will be used in that mode, you should be able to claim the 45W. Be wary however, as this may be something that will draw the eye of a reviewer.

Wouldn't it be to my disadvantage to list it at 45W though? not only because it will raise a red flag with a reviewer but because it would negatively impact the energy star to non-energy start equpiment ratio? can I list it at 1000w?

Kelvin,
If you believe it will be advantageous for your particular project to list this piece of equipment as "Non-Energy Star" and claim it as 1000W, you're able to do that. I was trying to outline the way you'd go about claiming the lower value.

I am a little confused. So what you're saying is, if I'm going to list it as energy star I would have to claim the 45W consumption, but if I claim it as non-energystar I would have to claim it at 1000w? Wouldn't the 1000W apply as energy star?

Sorry for the confusion,
From examination of the spec sheet, a reviewer would probably claim that unless the copier is working in the EnergySTAR mode, it's not an EnergySTAR device. Ergo, if you want to claim it as an EnergySTAR device, you need to claim it as 45W.
This isn't a certainty by any means, however. The spec sheet claims that the product is an EnergySTAR product, and a reviewer might accept that, but I would think it's less likely to pass.
I'm not certain with how this would affect your EnergySTAR calculation, so you can attempt whichever method you need to, but if it were my project, I'd claim it as an EnergySTAR device operating at 45W and provide a brief narrative claiming that the device would be used in the EnergySTAR mode.

Kelvin & Paul,
Here are my 0.02 for what it's worth.
-The printer is Energy Star rated
-The stated Energy Star mode is a power save mode. The printer cannot complete operations while in this mode. This rating should not be used as the "Rated Power." Here is an excerpt from the operating manual, page V:
"This printer automatically lowers its power consumption 1 hour after the last operation has been completed. To exit Low-power (Energy Saver) mode, press any key on the operation panel. To change the setting of the Energy Saver mode, see P.129 “Using the Operation Panel”."
-If it were me, I would document the printer as Energy Star and use the 1000w rated power.
Again, this is only my opinion for what it's worth. Best of luck!

Dax,
Thank you that makes much more sense, the "Energy Star Mode" had no definition in the spec sheet I was able to look at.
Kelvin,
I'd go ahead and follow Dax's advice on this.
