FAQs about EAc1.3 :

If pursuing Option 2, what is the scope of the energy model if the space shares a central plant, and what type of software should be used?

For Option 1, Zoning and Controls, is a thermostat considered an “active control capable of sensing space demand"?

Option 1: Zoning and controls

I've been working in a LEED CI: Retail for a small store in a mall. I'm wondering to persue the option 1: zoning and controls for the project but i'm not sure if the sales floor of the store should be classed as a special occupancy that requires active controls for OA. Do you have any tips for that? In case i have a single zone conditioned space that requires no active controls for OA. Would i still be eligible to earn these points? Thank you

I would need to check the Reference Guide to be sure but I think that the retail space would be a special occupancy. Since the space has highly variable levels of occupancy (like a conference room), it should have some controls beyond a thermostat. If you installed DCV on the single zone system it would probably qualify.
