It is clear that the low cost/no cost items uncovered during the investigation phase in EAc2.1 must ALL be implemented to satisfy the requirements of EAc2.2.
My Question: Must ALL of the low-cost/no cost items discovered as part of the ASHRAE Level I assessment in EAp1 also be implemented for EAc2.2?

Ruairi, typically the EAc2.1 audit and the EAp1 audit would be the same process, so yes, both measures would be implemented.

Tristan, sorry I should have clarified that I meant the retro Cx option under EAc2.1 and not the Lev II audit.
The EAp1 Level I audit would typically not be part of the EAc2.1 Retro Commissioning process and the types of low cost items included in the EAp1 audit would not neccessarily be major energy using systems operational improvements, e.g. "install vending misers on vending machines" verses "implement fan static pressure reset strategy"
The credit intent is:
To implement minor improvements and identify planned capital projects to ensure that the building’s major energy-using systems are repaired, operated and maintained effectively to optimize energy performance.
So my question remains, do you need to implement all low cost items identified in EAp1, particularly the ones that are not major building energy using systems operational improvements in order to satisfy the requirements of the Commissioning Credit EAc2.2?

The owner determines what is considered to be low-cost. So let them set the benchmark and any low-cost item you uncover during your retro-commissioning process that is within the owner's limit must be implemented.
This strategy has worked for me on previous LEED EBOM projects.
