IEQc1 requires confirmation that the building services have been designed in accordance with ASHRAE. A statement from the mechanical engineer is required to demonstrate this.

We have provided a statement from our mechanical engineer for the supplementary systems in the project, however not for the base building mechanical systems.

The company who designed and installed the base building systems is no longer in business. We have received email confirmation from the current contractor that his inspection of the systems confirms they were designed in line with ASHRAE standards, however he is reluctant to sign a statement along these lines.

Therefore we would like confirmation on the best approach for the LEED submission:

1. Do we submit his email confirmation which verifies he has checked the installed systems and they meet the requirements of ASHRAE, OR
2. Do we submit a statement from our mechanical engineer stating that according to information provided by the contractor, the system installed meets the requirements of ASHRAE

Thank you in Advance!
