I understand you can excluded up to tenant spaces up to 10% of the square footage of the building. However, our tenant spaces is slightly higher then 10%. We don't have control over tenant purchases, so for our other MR c 1-4 we are counting tenant purchases as 0% sustainable and estimating costs for them past on our own costs per sq ft. Would it be possible to employ the same strategy for this credit? Has anyone had sucess with that?
