Hi all,
Question regarding advanced energy metering. The credit require that any individual energy end use that uses 10% of more of the total annual consumption of the building must comply with advanced metering. The electricity-metering strategies also indicate that individual branch circuit meters can be avoided if 90% of a panel's load is directed to a single end use.
Here's the example I'm struggling with. I have a series of electrical panels dedicated to receptacle loads. On that same panel, I would like to circuit a couple of hand dryers and projection screens to the same panel. However, according to my panel load, these would likely take up at least 10% of the load on the panel. I find it difficult to believe that they would account for more than 10% of the total electrical load. That being said, would these I'll say miscellaneous loads, require branch circuit metering?
Thanks!

From an energy end use perspective these would be considered receptacle loads or plug loads even though they are hard wired. I don't think you have an issue.

Good to know. How about power-operated doors? Are there any other similar miscellaneous loads that would be considered receptacle loads?

Small miscellaneous loads are often included with the receptacle loads. The items you mention are all pretty small energy users in most facilities. I don't have a hard line cut off for what requires something to be broken out as a separate energy end use. It is not a matter of pluged in vs hard-wired. This is somewhat of a judgement call. Typical end uses that are often separated from the general receptacle loads might be kitchen equipment, elevators, process equipment in manufacturing, air compressors, etc. If something consumes over 10% by itself then it is obvious, if less than 10% overall I would probably look at what percentage of the miscellaneous load it is and anything over 20% or so of that I would include as its own energy end use. I think you also have some leeway and discretion to make this judgements call for unregulated process loads in general.
