Changes to Fundamental CX

There were some subtle changes to the prerequisite requirement for fundamental commissioning that can have some profound effects. As written, the commissioning agent must be on board during the design phase. The exact wording is:" Engage a Commissioning Authority (CxA) by the end of the design development phase. " This would mean that a project that decided to become LEED certified after the beginning of CDs would no longer be eligible for LEED since it does not meet the requirement of the prerequisite. I am assuming this is put in because of another change to the requirements which requires the commissioning agent to conduct a review of OPR, BOD and the design documents (drawings and specs). This is new on 2012, previously the CX agent had to ensure there was a BOD and OPR for Fundamental Cx. Additionally, Fundamental Cx now requires the CX agent to "Prepare and maintain a Current Facilities Requirements and Operations and Maintenance Plan documenting information necessary for efficient building operations." While I think this is a great document to be produced it might be better served in the enhanced CX credit since the inclusion of all of these items will significantly drive up the cost of LEED certification to meet this prerequisite. I believe this will force many owners, developers and government agencies to reevaluate what green building rating systems they will use and will result in a decrease in market share and impact.
