You'll need to be able to justify why the conventional case is the norm, and how the proposed case is "exceptional" - you might consider submitting a CIR through your project's workspace in order to solidify the details in advance.
One thing that might help justify taking credit is if the cost of the proposed configuration is more...i.e. show that the client is not taking the easier low-cost approach. If the cost of the proposed case is less, then you might explain why it isn't the default solution for the client, there must be some other trade-off involved.
If you end up claiming the exceptional calculation then the baseline and proposed will have the higher conventional computer usage rate (but with all other ECMs included in the proposed case). The exceptional calculation will be a modified proposed case with lower power usage, in addition to keepign the other ECMs.
It is possible that you end up not claiming the exceptional credit, in that case the client will still benefit by modeling the proposed and baseline cases with the lower power usage to start with, which does reflect the design intent. The project application still "gains" energy credit by having a smaller denominator for total usage, so that all of the other ECMs have a larger contribution, relatively.
I wasn't clear from your email, but it sounded like the 12 point option assumed high usage in both models. There might be an intermediate percentage where both models have lower (but equal) process usage from this computer system that results in ~13 or ~14 points as an example, without using the computer terminal energy reduction as an ECM.

Dear list,
I googled a bit for this problem and didn't find anything immediately so here goes. I am working on a building that has huge computer systems that cause 40% of kWh to go to process loads. In order to meet LEED goals the owners went for a server/terminal solution where there is a 920W server and 19x75W terminals instead of 19x270W desktops. When I apply this as an exceptional calculation the models go from 12 points to 20 points which looks like it will raise flags.
My questions is:
Does this situation sound like something a reviewer would go for as an exceptional calculation?
Do I model the baseline and proposed identically with the higher process load or the lower one?
Thanks,
Jacob

Subject: [Equest-users] Exterior Windows misplaced
I am very new to eQuest and am working on completing my very first model. I imported a .dwg file to set up the building footprint and zones and have begun on exterior elevations. I have been inputting my exterior glazing using the "Custom Window/Door Placement..." option in the DD Wizard. I have all the windows input correctly, but when I back out and go to the 3-D view of the building, some of the windows are on the wrong walls, and some I am not seeing at all (unless they are 'doubling up' on one of the other walls). I am not sure if I have made an error in the earlier stages of constructing the model thus far, or if this is some type of glitch. Does this sound familiar to anyone? Any advice?
I have seen that I can go in and change the parent wall for the misplaced windows in the detailed edit mode, but would just like to figure this out for future models going forward.
Thanks!
Ryan

Welcome to our group Ryan :)!
Pretty impressive, first model, dwg file, custom windows-you are ahead of the game....
There can be many reasons why you're having issues.
What we typically do in a request like yours is to ask you to attach/zip your pd2., inp and bdl file and send it to the users list-much easier to troubleshoot.

There is a good possibility you have made an error on the CAD input. In order to find it you are probably going to lose your detailed window input. Start by making a copy of where you are now and go back into the wizard. Work with your copies keeping your current file safe.
For your information I never do a detailed window/door placement until I'm sure everything else is working correctly in the DD wizard. I just put the windows in as a percentage of the wall area and finish the wizard. I also keep lots of copies, lol, you never know when something crops up. As you will find with your copy going back into it will probably delete your detailed window input. Hence the reason I never do it until I'm sure everything else is correct. Basically a 30 second place holder to keep the wizard happy. Doing this allows me to go back into the wizard and keep making adjustments and finding errors until I'm satisfied it is running smoothly. If you have nothing to lose you can do this for days.
The DD wizard is a great, easy interface to use. You may be able to solve your problem in the detailed edit area but it is several magnitudes more difficult if you are a new user or even an experienced one. The most successful are used to DOE 1&2 before the eQuest interface. This still may be able to be done but you have to find the problem first.

Subject: Re: [Equest-users] Exterior Windows misplaced
Thank you for the pointer! I have attached the requested files. As you will be able to see if you go into the custom windows editor, I have input a row of windows on the western-most wall, but when you go back to the 3D view they appear on the northern end of the east elevation. There are also windows on the northern wall adjacent to the western-most wall that are gone and i'm not certain where they disappeared to. There are a few more issues with misplacement, but I'm sure if one can be figured out it will likely solve the problem for all of them.
Thanks again!

You seem to have the first floor with a 'floor-to-floor' height of 25 ft and a 'floor-to ceiling' height of 8 ft. which seems a bit peculiar (the same thing for your second shell)
Your second shell is only located at a height of 10 ft so your shells are overlapping. I'm not sure if that's effecting your windows appearing but it's definitely somewhere to start!
