We have a Core & Shell project that is complete but doesn't have tenants.  The owner is having problems getting tenants (and their layouts/ HVAC needs) so we don't have a way to test the equipment.  The only functioning system at the moment is a DOAS with an ERV and supplemental heat if required to keep the building from freezing.  The heating and cooling will eventually be supplied with a VRF system but the branch boxes are not connected to anything due to the lack of tenants.  Is there a lower threshold to certify this requirement without having tenants tap into the main heating/ cooling systems in an empty building?  Or do we have to have tenants to complete?  The commissioner does not want to test the minimal equipment and have to come back and test again.  Any help appreciated.
