No-break (UPS - UPS - Uninterruptible Power Supplies)

Hi Vitorio- Any luck on this?

I thought I recalled an GBCI issued addenda that stated new categories were to be included in the same general categories already required for evaluation (Office equipment, food service, etc) but cannot locate it....may be falsely remembering that. UPS and Enterprise servers are both new categories under "Computers" in the ENERGY STAR website, which is part of a broad classification of "Office Equipment" so I would expect they need to be included in LEED calcs. They can represent a LOT of wattage so best to catch them and ensure they are ENERGY STAR rated in the planning/specifications stages of a project.

Thoughts?

I am not sure if this is still a question or condfusion in LEED User but it does crop up on current projects.

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 assume the logic is that a UPS conditions power supply, and only energy consumed is the energy associated with losses. E.g. a 100 kVA @ 0.8 pf iand 95% efficient consumes only 4 kW, not 80 kW.

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.

LEED Interpretation 10400 was updated on January 5, 2018, and provides guidance to determine the UPS "rated power" for LEED calculations purposes.
