Thank you Anderson,
In this case, the retail is more than 20,000 ft2 so I need to select a different baseline system.

My follow-up question: the building is more than 5 floors (majority is residential) but the retail only occupies the ground floor. Would I select System 7, VAV reheat as the building is more than 5 floors.

Or would I select System 3 for the retail because the that space only occupies 1 floor?

I believe that if the retail gross floor area is less than 1900 m2 you can use system 1, otherwise you can use exception a of section G3.1.1.

Standard 90.1-2007. The building is a high rise residential with the ground floor mainly retail. 90.1-2007 says to use the predominant condition to select the baseline system. In this case residential is the predominant condition therefore I am assuming the retail spaces would also have System 1, PTAC? Heating is fossil fuel.

Choice. It is perhaps the most distinct and dignifying characteristic of humans. Consciously and with understanding, we choose what is true, honorable, right, pure, lovely … or otherwise. Like the rest of humanity, my choices don’t always align with true, honorable, right, pure, and lovely, but I know those are what I set my sights upon. I choose them.
