The energy cost offset from onsite renewable energy cannot be used to demonstrate compliance with the prerequisite. Can this cost offset still be credited to the proposed energy cost savings for this credit?

CI-v4 EAc2:Optimize energy performance

Errors in the ASHRAE AEDG Table excel file?

The workbook available on the USGBC website does not appear to be properly updating when changing the climate zones. Here are some examples for k-12 schools:

  • Climate zone 6 in the workbook lists R-13.3 (R-2.3) c.i. for the Walls - Mass. This is from climate zone 5 in the pdf.
  • Climate zone 7 in the worokook lists R-30.0 (R-5.53) ci for the Roof - Insulation entirely above deck. This is from climate zone 6 in the pdf.

Yes, there appear to be mistakes in the workbook. I would recommend noting the correct recommendation in the "Project Specification" column along with the design so the reviewer can confirm that the design meets the correct recommendation.
