I am working on a cultural center performance space in San Diego with very few HVAC system components. For ventilation, there are exhaust fans that induce outdoor air into the building through the operable doors and windows. For cooling, there are two window air conditioning unit that serve a small portion of the building (one multi-occupant office and a computer server room); the remainder of the building does not have any cooling. There is no central heating system in the building. There is a domestic hot water heater as well as a lighting system. There is also a 2 kw photovoltaic system on the roof.
We are interested in pursuing the retrocommissioning option of EA2.1, as well as EA2.3. Will these points be possible with these limited systems? Do these systems meet the intent of EA2.1 and EA2.3?

Absolutely Nate, especially since the PV system can be part of the process. The LEED reference guide does not specify a minimum quantity or size of system to qualify for the credit. Although, I would encourage your team to be diligent with whichever path is chosen. Seemingly small scale Retrocommissioning projects can sometimes turn out to be quite tricky.
