In October 2005, "Getting it Right" loosely defined levels of rigor for commissioning tests. That was intended to help building owners understand the wide variety of testing approaches available from commissioning providers. Last month (November 2005), and this month, I am presenting a qualitative discussion of the advantages and disadvantages associated with the various levels of rigor. The intent is to help building owners decide what is most appropriate for their projects prior to soliciting commissioning services.
To help this column stand on its own, I'll repeat the definitions for each level of rigor. Last month I covered the three lowest levels, and this month I'll complete the discussion with the two highest levels of rigor.
