Good point (about unmet loads).
What does “indirectly conditioned” mean? If there is some type of zone air conditioning, you will not have unmet loads.
Thinking about other modeling strategies:
· How about specifying a DX or heat pump system with COP = 10,000 and Delta pressure rise = 0? (E+ will accept these values; I have used them.) Approximately zero energy will result, but you will sacrifice correct heat transfer through walls which adjoin conditioned zones.
· What if you specify a specific airflow rate in Sizing:System and also make the coils unavailable during normal operations? (I think sizing and operation are calculated separately.)
· Let the unmet loads occur, report the hours which occur in the unconditioned zones, deduct those from the total and let the GBCI people know what you did in a narrative which explains it.
· If those don’t work, you could model the zones with heating and cooling, report the energy using a Meter:Custom and deduct that energy from t
