I am seeing more and more project requirements (for new buildings) mentioning TBCx (Total Building Commissioning)- which is based on ASHRAE Guideline 0. I'm not real familiar with it, and don't know what I need to plan for to meet this requirement. Does anybody know how this level of Cx compares with the levels required for both LEED Fundamental and Enhanced Commissioning? Thanks!

Matt, TBC is the concept of commissioning more than just the LEED-required systems. It does not necessarily change the commissioning process beyond the enhanced Cx requirements, it looks at additional scope of systems (envelope, life safety, emergency power systems, etc.). As with many things, the scope of TBC is defined differently by different organizations.

It has been established that within the context of a Federal Gov't Design-Build project, the contractor 'can' sub-contract a CxA to act as the 'disinterested 3rd Party'. The CIR was authored and appeared on the last version of the CIR database. However, under the new 'beta' database I am unable to locate the exact CIR. I am currently involved with 'many' such projects where the contractor has sub-contracted a CxA or CxA firm.
