Revised Points Thresholds APC

We would like to clarify the possible Alternative Compliance Paths (ACP) options for the EAc1 (our project is C&S). There are the three standard ways to achieve credits under the EAc1: Option 1 - Whole building energy simulation, Option 2 - Prescriptive compliance path: ASHRAE Energy design guide and Option 3 - Prescriptive compliance path: Advanced buidings core performance. Next to these three options, there is also the ACP Alternative Energy Performance Metric EApc95, as described here: https://www.usgbc.org/node/7489409?return=/pilotcredits/New-Construction/v2009 Next, there is also the LEED 2009 Core and Shell EAp2-c1 Alternative Compliance Path described here: https://www.usgbc.org/resources/cs-2009-eap2-c1-acp In our understanding, the second ACP is applicable only within the EAc1: Option 1 - Whole building energy simulation, as it is based on energy modeling. Also, this APC is completely separate from the first APC. Is our understanding correct? Many thanks
