UPS equipments for energy star

Yes, all new Energy Star rated equipment must comply.

Making reference to LEED Reference Guide for Green Interior Design and Construction with Global ACPs p30 in the table under "The following equipment is included in the scope and must be accounted for in the credit calculation:" UPS is not listed under Computers and Electronics!

I would agree with excluding UPS based on the logic that a UPS conditions the power supply to equipment, and the only energy consumed is the energy associated with the UPS losses. E.g. a 100 kVA @ 0.8 pf iand 95% efficient consumes only 4 kW, not 80 kW.

It is also worth checking the ES specifications for a given item, as some items, say a display unit may be of a size outside the sizes covered by ES.

John, I can't find your reference above. Page 30 in the ID+C Reference Guide falls within SSc1. Page 30 in the ID+C Rating System is MRc2. In any case I do not think that because it is not on a list means that it is not included.

UPS falls under office equipment within Energy Star and the Reference Guide and Rating System documents clearly state that all Energy Star eligible equipment is included within EAp2 and EAc1.4.

Hi Marcus, I refer to page 30 of the ACP document. http://www.usgbc.org/sites/default/files/LEED%202009%20RefGuide_CI_Globa...

You may be right about the UPS but then I would ask if the power rating is the full rating (80 kW in my example), although losses (4 kW) seems more logical. Encouraging the use of ES rated equipment and appliances is to reduce electrical load and, where used, cooling load. Assuming UPS rating is used, and the equipment its serves is not ES rated, then the power rating would often be much larger than other equipment and appliances, yet the actual equipment power may be relatively small, likewise the contribution to heat gain and cooling requirement.

As I mentioned, a range of IT equipment may be under ES, but if the particular item is outside the ES specification for obtaining the label then I believe that ES should not apply. I do not think LEED intends to dictate all equipment needs for a project, rather to encourage selection of ES rated equipment when it is available.

Thanks for the link - too many documents to keep track of!

I see your point and am not sure what would be the power rating. To the forum - Any other thoughts?

I agree that if ES specification does not apply then it does not count toward this credit.

I think LEED intends to save energy and project teams should strive to do so.
