Area of the building

Hi everyone,

I am working on this warehouse (distribution center) building with 50,000 sf of office space (VAV system) & 1.5 million sq ft of warehouse (makeup unit of only 13,500 CFM with heating only). When I do calculation on excel sheet for EUI (total area 1.5 million + 50,000), it's around 15 (for design case) but when I look into BEPS report, it shows 395 EUI which doesn't even make sense. It seems like it's not reporting the area for distribution center and doing EUI calculation just for office space area. Can you please let me know how to make equest report the whole area of the facility? Please find the attachment of eQuest files.

Thanks!

Harshul,
I didn't open your model but I suspect you are not modeling the entire warehouse as "conditioned". The area used in the metrics on BEPS/BEPU are based on conditioned area. See the LS-C report for the conditioned area in the model. Based on your numbers below, your modeled conditioned area is only 35,000 ft2 or so.

Thanks for the reply. I already looked into LS-C report about it but if I see in my model I mentioned spaces as conditioned. That's how I assigned "heating only" system to them. Please see the snapshot. Is there somewhere else too I need to change some inputs? Where did you find those spaces unconditioned in my model? Can you please send me snapshot of that?

Thanks!

Thanks for reply. Yeah I checked my LSC. Sorry about numbers. My total "conditoned" office area is 35,000 sq ft & "unconditioned" office area is 15,000 for future. For unconditioned office we cant take credit. But if you see snapshot given below, I have assigned warehouses spaces as conditioned where I have given only heating schedule only (for makeup unit air system as I mentioned in my first email). All warehouses are named with "WH". Is there any other spot where I need to make necessary changes so that eQuest can report these areas too?

Thanks!

Harshul,
Go to the spreadsheet view for spaces, not zones, via the Building Shell or Internal Loads modules. I believe that is how the conditioned area is determined.
