[Equest-users] Baseline Modeling

[John Aulbach]

My two cents..

Before you make two Detailed Edit Models (one baseline, one proposed), make sure you have all the correct schedules and ancillary loads the same in ONE Detailed Edit model. You have quite rudimentary schedules in the Wizards (probably developed on Mars), so you need to insure any additional schedules (or schedule changes) and load additions are made.

THEN make your two Detailed Edit models.

Thanks Paul,
 
Someone later told me I was incorrect and I’ll be changing the way I do it as well. Starting proposed and working backwards.
 
Thanks,

Hello Omar,
 
These are the steps I suggest you follow to complete the proposed building and the baseline building models most efficiently:
 
1) Model the proposed building first. Do everything you can in wizard. Keep a copy of the model at this stage so that you can easily go back to this state of your model if necessary.
2) Save two new copies of your model- one for the proposed model to be completed in the detailed editor and one for the baseline model.
3) Complete the proposed model in detail editor
4) Go back to the model you saved in step 2 of this process as the baseline model and change your selections in the wizard to comply with ASHRAE 90.1. This is quicker and easier than changing all the values manually.Keep a copy of the model at this stage so that you can easily go back to this state of your model if necessary.
5) Save a new copy of the baseline model and complete it in the detailed editor. 
 
This process allows you to do everything you can in the wizard for both the baseline and proposed building models. It also helps to ensure that schedules and other aspects shared by the two buildings are modeled the same as required by ASHRAE 90.1. 
 
 
I hope this helps,
 
Paul

>Dear all,

>I am modeling a school using eQUEST. I have entered the values corresponding to the proposed building (like the specifications given). I would like to model the baseline building according to ASHRAE 90.1 standard. 
>Do I have to change the U-values, HVAC strategy, Window/wall ratio, and the other stuff manually? That is, shall I open the ASHRAE standard and start changing all values one-by-one? The ASHRAE Standard 90.1 isn’t recognized by eQUEST such that it can create the baseline case alone? That would save a lot of time!
