Does 10-4 Mandatory provision apply for process electric motors?

I think that only motors that are used for regulated purposes of the 90.1 Standard are covered by 10.4. So industrial motors would not have to meet all of the requirements.

it is really mandatory to comply with section 10-4 of ashrae 90.1-2007 if building simulation is choosen to comply for EAP2?. If building efficiency comply with required percentage (5-10%) although electric motors efficiency is less than that in table 10.8, it is valid? For projects and eelectric motors in Europe there is no other standart aplicable instead of NEMA? IEC 60034-30:2008 or EN/IEC 60034-2: 1996 standart are not valid? There is not other rpm values? for table 10.8, usually it is work with 50Hz in Europe. There is no ASHRAE compliance form, for this mandatory requirement?

LEED project must comply with the mandatory provisions and show the minimum percent savings. I am not aware if the European motor standards have been granted equivalency or not. To be honest, unless you point it out in the documentation, this issue would not come up on a typical LEED review. Although the electrical engineer (or other party) is stating that the project complies with the mandatory provisions.

Oh so you want your cake and eat it too? :-) You can claim savings but would need to do an exceptional calculation. Using these efficiencies as the baseline makes sense to me.

Shouldn't the local conditions be considered? I mean, ASHRAE documents are conventional practice for the United States, but in other countries other documents should (shall?) be considered, shouldn't they?

Yes they should. So if the local country or region has a set of standards that is reasonably equivalent to the US-based ASHRAE standards you can always make the case for using the local requirements and practice.
