In the 8/13/10 document for Treatment of District or Campus Thermal Energy in LEED V2 & 2009, Appendix A says that District Energy Systems have no effect on any EA section prerequisites or credits. Does this mean we no longer need to follow the 8/13/2010 document?

For CI projects only that is correct.

We are using appendix G for modeling in lieu section 11. Manual (LEED-CI) says we can use appendix G with Table 2. Table 2 refers to Table 11.3.1 of Section 11 where proposed design shall use actual system, in our case this is purchased chilled water. The budget building used Table 11.3.2 for HVAC equipment which is electric. This sets up the problem that the August 13, 2010 document seems to address, moreover, appendix A appears to be incorrect, the DES will have an impact on the calculations. Do you agree with this?

Are you referring to the Advanced Energy Modeling Guide? Table 2? Is this Table 2.1 from the Guide?
For future posts - if you expect complete answers please provide complete questions.

Sorry. The table 2 is from the LEED Reference Guide for Green Interior Design and Construction, EA Credit 1.3 (page 170)

This forum is for EAp2 not EAc1.3. Appendix G is allowed under EAc1.3 but it is not allowed under EAp2 as far as I can tell. Section 11 is used to demonstrate compliance and that is why it must be used for this prerequisite. It is the alternative used to demonstrate compliance if the project cannot meet all of the prescriptive requirements.
See note e under 90.1 Table 11.3.2A. If the proposed has purchased chilled water the budget system does as well. This is the same as Option 1 in the DES so Appendix A is correct.
