Long Term Commitment

I got I bit confused with the period of time which is considered to comply with the aim of this credit. At first a thought the 10 year commitment counted from the date of the LEED certification process, however after reading some of the comments posted here, namely the one post by Steve Khouw (Aug. 24 2011) and after reading the LEED Interpretation with the ID10052 (05.09.2011) a got confused... So, Steve states that “the 10 year rule starts when the tenancy agreement was signed, so if the renovation project of an existing tenancy, you count backward to the start of the lease” while the LEED Interpretation quotes that “Lease terms of less than 10 years, regardless of the owner's lease history, do not satisfy the credit requirement of a minimum 10 year term”. And hear was where I got confused…from when do I count the 10 year commitment? I have a project which has a leas contract since August 2000, which is auto-renewable every year unless notified otherwise, and in the last 2 months they renovated the entire occupied area (spending more or less 1,000,000€). Given this, do I comply with the credits aim? Or do I need do enforce the necessity of my client do redo his leas contract in which is specified the 10 year commitment, starting this year, 2011. Thanks.
