When helping a client prepare packages for a grant they are pursuing, they needed to know how LEED-EB and LEED-CI differed with respect to commissioning (Cx) requirements. A quick search yielded a helpful, plain spoken article, with even more helpful comparison charts (1, 2, 3, 4), in a February edition of Heating, Piping, and Air Conditioning (HPAC) Engineering magazine. The charts show fundamental Cx requirements, enhanced Cx requirements, and scope by system, comparing all major LEEDv2 systems and even pulling requirements from the pilot versions of LEED-CI for Retail and LEED-Healthcare. I'm not aware of any major changes among Cx requirements for LEED 2009 editions of these systems, so everything should still largely apply.
A completely legible comparison of the scope of Cx for each system
I haven't had much opportunity to peruse their website in too much detail, but their Popular Articles section seems to be filled with practical info that I'm going to refer to in the future. Well done!
