Karen & David,
Thank you for your input on this topic. I tend to agree
with both of you about the intent but I would have a hard time pointing
to any specific text if anyone were to disagree with this
interpretation. The wording is a bit unclear. Pages 5 & 6 seem to simply
refer back to tables 2 & 3.
Good luck with your project Karen...

I am also in the middle of a DES project at the moment. The way that I
interpreted Step 1 and 2 is as follows:
Baseline: all downstream (on-site) equipment, envelope components, etc,
as in Appendix G. heating and cooling is purchased from a DES system.
Proposed: all downstream (on-site) equipment, envelope components, etc,
as designed. Heating and cooling is purchased from a DES system.
Baseline: all equipment is modeled as on-site. Boilers and Chillers are
to be modeled as designed in Appendix G. Utility rates are to be local
Proposed: building is to be modeled as built. Heating and cooling is
purchased from a DES system, energy costs must take into account DES
production and transmission losses.
In my opinion, the vocabulary in Table 1 is confusing, but the
guidelines on pages 5 and 6 seem pretty clear. Am I on the same page as
everyone else here?
