The LEED reference guide is very particular in the language that they use to describe the intent and stragegies for EAc5.1 and 5.2 for C&S as being distinct from NC & Schools.
For NC& Schools, both options 1 and 2 both describe that "the M&V period must cover at least 1 year post-construction occupancy". However, there is NO such description of the M&V period for C&S for options 1 or 2, nor do the addenda for these credits add any such language for options 1 or 2, (or for option 3 added by addenda with post date 2/2/2011).
Has there been an official clarification/requirement for C&S M&V period by GBCI?

I am not certain about an official clarification. But absent one I would think that it would be the same as NC.
An M&V period of less than a year does not make much sense for most projects. The model is measuring 8760 hours so to calibrate the model it should be based on the same. I suppose if the weather is the same year round or has no impact on energy use it could be done on less than one year's data but you would need to fully explain how this would be done in the M&V Plan.
