Hello everyone, 

we are setting energy modeling strategy for a major industrial plant with an on-site DES used for heating. The selected modeling Option is Option 1-Whole-Building Energy simulation.

With regards to the DES modeling, we would like to avoid the Path 1 ASHRAE 90.1-Appendix G approach (purchased energy) and apply the Path 2 Full DES performance accounting (or Path 3 Streamlined DES modeling). 

I would like to clarify, if DES modeling Path2 or Path3 can be applied, if the project is registered under the Campus Approach?

Many thanks for any advice,
