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"?

I have read Interpretation #10134 and 10135, but based on some of the comments below, I would like some additional confirmation. Does new system-level mechanical equipment that serves 60% of the space need to be installed (to pursue item 1 or 2 in #10134), or can this apply to existing systems serving new zone-level equipment (i.e. VAV reheat boxes)? Otherwise item 3 will have to be pursued, meaning that existing equipment will have to meet all relevant criteria.

Steve, you must install air-handlers supplying 60% of the flow or heating/cooling equipment supplying 60% of heating/cooling capacity to pursue the first two options under Intepretation #10134. If the scope of work for the LEED CI fitout only includes new ducts and VAV boxes, then you have to show that existing or base-building equipment meets the requirements in the CPG.
