Ok, frank question - I have invested countless hours hunting the myriad of similar and overlapping product directories to pre-qualify LEEDv4.1 compliant products (Both MR & Low emitting) - in hopes of finding enough comparable commodities to allow for semi-open or open performance specs (3 pre-qual manfs, or just tech criteria and no manf called out).

However - thus far I am not finding enough products to viably pursue Option 2 even using proprietary specs - "thou shalt purchase this (10) exact products".......

As such, it seems inappropriate to mandate achievement of Option 2 or even a specific compliant product quota to be met by a General Contractor within contract documents (tender/bid specifications, etc). 

Am I missing something? How is everyone else approaching pursuit of Option 2.....assuming its being actively pursued!
