[Greenbuilding] LEED Commissioning Payback Time

[Amy]

Does anyone know that buyback or payback period for the cost of 
commissioning on a LEED project?  Is there an average for different 
ranges of construction cost....

I'm trying to make the case for a town to pursue LEED certification for 
their new Town Hall which is also going to be the first building to 
employ the green building strategies that will soon be required as part 
of their pattern book for future growth in the town. However, the 
planning commision is concerned with the additional cost of commisioning 
involved with LEED certification.  It's only a 9,000sf bldg. and 
commissioning proposals are on average 1.5% of construction costs, but 
they feel like thats a lot of money for the LEED name.  However, if they 
thought that there is evidence to support a buyback period inside 25 
years.  They are willing to provide the additional funds.

Any facts, figures or suggesstions...

Thanks,
