WE ARE WORKING ON LEED CERTIFICATE FOR CI BUILDING (14000 SQUARE FOOT) THE POINT IS, WE HAD RENTED OFFICE AND THE HVAC SYSTEM WERE INSTALLED SINCE FIVE YEARS AGO, NEWLY WE INSTALLED NEW HVAC EQUIPMENTS .. THE QUESTION IS HOW CAN WE COMMISSIONED THE OLD EQUIPMENTS AND SHOULD WE COMMISSIONED THE OLD SYSTEM OR ONLY NEW SYSTEM???? .. AND IS IT IMPORTANT TO INCLUDE THE DATE OF INSTALLATION IN THE COMMISSIONING REPORT??????

Tristan asked me to take a look at this, and I am sorry it has taken so long. If I understand the question correctly, you have a larger TI project that has existing HVAC equipment and you also had to install some new equipment. All systems that serve the space must be commissioned, but only that equipment that is in your space and under your control. If all your HVAC is in your space, then you do it all, if there is some central equipment (maybe chillers providing cold water to your space) then that system does not need to be commissioned.
All systems (including existing) will also need to be brought up to current standards are required for LEED certification, for example meeting the referenced ventilation requirements. It is always good to give as much information on any system, so in this case I certainly would include dates that equipment was put in service in the report.
