I'm noticing this happening after I create a model in the Wizard. I get through the whole process and hit "Finish" with no issues. I save the file, then enter into Detailed Edit mode, and save that as another file. I can make changes as usual and ensure no BDL errors, but when I try to simulate anything, the BDL Load File Progress gets to 99% then stops. A pop-up message appears declaring "Building Energy Simulation Tool has stopped working", and I have no other option but to close the program. This happens with both the Wizard and Detailed versions of the file when I try to open them. I've tried starting a fresh file and importing the INP, but the same thing happens.

Am I doing something wrong in the Wizard that is corrupting something? Does anyone know how I can keep what I did in the Wizard and get to a workable file?

Thanks!

Thanks for your response. The project is in CA Climate Zone 13, ASHRAE zone 3B.

I've modeled four buildings in a single file in eQUEST. They're small (the largest is 12,000 square feet), so individually would fall under system type 4 (which is how I've modeled them). The buildings will not share any systems when built. I wanted to confirm that using type 4 is correct (because I've modeled similarly-sized offices that were on opposite side of gigantic warehouses and LEED reviewers insisted on one system type 6 for the whole thing. Granted, it was still one building).

Additionally, my fan loads seem high, though my schedules and outdoor air are as they're supposed to be. Any quick suggestions on things to check, or should I expect high fan loads with system type 4 in a cooling-dominant climate?

Thanks!

I suspected as much, thanks for confirming.

I am using eQUEST. The model is for office spaces that have yet to find tenants. The proposed model is based on the minimum requirements of the lease for tenant fit-outs. In this case, tenants are required to have equipment with a minimum SEER value of 15. I can model this just fine, but do I need to keep the oversizing that I had in the baseline (since there is no specified equipment and therefore no specified capacities)?

Thanks,

Hi all,

I'm new to this and it might be a stupid question, but I'm concerned about selecting the right system for my model.

I'm modeling a trade school of sorts, with lots of heat pumps (70+). Unfortunately I can't upload anything yet to give an example. I modeled them as packaged single zone units, the larger units with 2 speed fan control and the smaller ones as constant volume (does that seem right?). I'm concerned because of the jump in fan usage. Fan kWh increased 151% from the baseline (ASHRAE System 6). The proposed design does increase CFM and OSA, but does this make sense?

Thanks in advance for helping out a beginner.
