Combining Parametric Components

Hello,

Does anyone out there know whether or not it is possible to take parametric components that are currently each being used for individual parametric runs and combine all of them under 1 parametric run?

Currently, I have a model where I have analyzed 13 envelope measures using parametric runs. Now, I would like combine all of them into 1 run called envelope measures. Is this possible?

You can run the parametric runs incrementally or cumulatively. To run
them cumulatively, in the parametric run dialogue, you need to base the
run on the previous run (you can base the un on any parametric run
preceding it).

Jeremy, What Vikram says is correct. However, I believe you STILL need to add all of the Parametric components into one run to compare to the Base. Run #7 will compare to Run #6, but Run #7 won't have Run #6 parameters in it, as well as its own.

In other words, the parameters will not accumulate as the run numbers get bigger. I believe you still need a cumulative run will all envelope parameters added into that run.

Actually when you run parametrics cumulatively I believe they do take the properties of the previous run into account. So for example if run#6 makes your glass darker and run#7 adds daylight sensors, run#7 will assume the darker glass.

I am new to Equest. I see that Equest does windows (p. 7 of 50 in schematic
design mode) but what about window film?

Thanks

Thank you very much for your help! However, I don't believe I explained my question well enough. In my model, I currently have 13 envelope measures I have analyzed by creating 13 individual parametric components that are assigned to 13 individual parametric runs. When I analyzed them, I compared each measure to either the baseline or a previous measure as appropriate. Now, I am finished analyzing envelope measures and I would like to analyze about 10 HVAC measures. I would like to keep my original baseline, but I also want to analyze the HVAC measures assuming that the envelope measures will be incorporated into the building. So, I would like to combine the 13 envelope components into 1 envelope run, rather than 13 individual runs. Then, I will compare HVAC measures to either the new baseline envelope run or previous HVAC measures as appropriate.

For example, I currently have the following configuration:

Envelope Run-1
Envelope Component-1
Envelope Run-2
Envelope Component-2
Envelope Run-13
Envelope Component-13

And I would to have to have the following configuration:

All Envelope Runs-1
Envelope Component-1
Envelope Component-2
Envelope Component-13
HVAC Run-1
HVAC Component-1
HVAC Run-2
HVAC Component-2
HVAC Run-13
HVAC Component-13

Is it possible to combine the envelope components I have already created into 1 envelope run, or do I need to recreate all of the envelope components in order to accomplish this?

Thank you for your help!

If I understand your question correctly, here's one possible solution.

Run the 3 runs cumulatively (i.e. 13 based on 2; 2 based on 1). Run 13 now represents this:

All Envelope Runs-1
Envelope Component-1
Envelope Component-2
Envelope Component-13

You could:

A) Continue your HVAC runs based on run 13 (you don't need to run the previous runs each time).

B) Alternately, eQUEST creates .inp files for each parametric run (it should be located in the same folder with the suffix having the run number (you will look for a -13 suffix).that you can open as a new file and continue from there. When you open an inp file (as opposed to a PD2 file) it will create a new PD2 file and a new folder for you.

Hope this helps.

I prefer to create a second start-point baseline to include all envelope measures as a separate file so that you won't get confused when you are playing your HVAC measures these will be based on new baseline.

Bill-

I would recommend building any window construction outside of eQuest (in
Window5) and importing it back into eQuest.

You can find Window 5 here:
http://windows.lbl.gov/software/window/window.html

It's pretty user-friendly and is much better than creating a user-defined
window construction in eQuest.
