[Equest-users] activity area allocation and zone group definitions

[Paul Brooks]

Thank you so much.  YOur description is how I thought things would/should work, 
but, as Ronnie said many years ago "Trust, but verify"!

I am again a happy camper for now.

Hi Paul,

These screens were an anomolie (sp?) to me until just this year thanks to a 
younger fellow simulator who uses them quite efficiently.  In fact, I always 
skipped out of the wizard when it came to these screens until I took the time to 
learn how to readjust & reallocate the % space inputs on these screens.   After 
learning to do this I now spend less time on the back-end (ddedit mode) 
adjusting my HVAC system assignments... Yay!

Here's my attempt to explain what I've learned.  I'll call out my colleague Dan 
W. for help on this one if I mess it up...

Screen 13 is your % space based on the WHOLE BUILDING floor area.  When you move 
to screen 14 this is where you actually assign HVAC systems to your zone 
groups.  A zone group is a group of zones that can be assigned to the same HVAC 
system. (NOTE:  at this point you will want to have created your basic HVAC 
systems types already in the wizard.  This was a backward step for me at first, 
but it works for when you switch to ddedit mode.)

So in  screen 14 the % space for zone groups is based on the total floor area of 
all the zones you want to group together.  (at this point you should also have a 
basic take off of floor area for your thermal zones.)  Now after you have 
"grouped" your zones that you want together you need to revise the % space 
numbers in the top of the screen.   (I've included a screen shot of one of my 
models where I used the zone groups.)  Note how I have zeroed-out some of the % 
space input for other zones that I have not grouped into my specific group I'm 
calling "Conference Center."   With the revised % space numbers make sure that 
they add up to 100%.

So to answer your question, when you use Screen 14 correctly these inputs will 
override screen 13.   If I should clarify anything better let me know.

Pasha

Does anyone have any idea which of screen 13 or 14 in the DD wizard overides the 
other?  I am using zone group definitions to give dtail on how individual zone 
space is allocated (screen 14 of 25), but that does not seem to affect the 
activites area allocation, (screen 13 of 25).
