I am working on an industrial LEED project in KSA. Most of electrical loads are for the industrial processes itself (i.e production line), while the other remaining loads are for HVAC and Lighting. I have noticed from a LEED Interpretation that in such cases similar to my case, I can model energy costs (EAc1) based on all loads except for the industrial process loads. If my understanding is true, then I can calculate the on-site renewable energy percentage mandatory for that credit (EAc2) following the same principle as in EAc1 (i.e. excluding the cost of energy specifically needed for the industrial processes).
