Who can perform enhanced commissioning services?

If my project uses a District Energy System (DES) is enhanced commissioning required for the DES?

NC-2009 EAc3:Enhanced Commissioning

Late Enhanced Comissioning

Does exist any time limit between the construction conclusion and the start of enhanced comissioning? i.e. To comply to this credit, can I contract the enhanced comissioning in a building that has been occupied for 11 months? Thank you!

Are you considering enhanced commissioning for a NC project that is already complete? If the commissioning would be for systems that have already been constructed, the credit is not achievable. The commissioning design review of 50% CDs has to be completed by the party providing enhanced commissioning at that point in the schedule - so there is time for comments and changes to be incorporated into the final construction documents. If you're considering enhanced commissioning for a tenant improvement pursuing LEED CI in a building that is already built, well, that's a different story....

Agreed. Enhanced Cx should (must) be engaged during the design phase of the project (hopefully during schematic design). Commissioning of a completed building does not comply with the intent of the credit.
