To all:
I have a building complex consisting of 8 buildings. In one of the
buildings are the boiler and chiller that service all of the building
through various pipes. The other buildings don't have their own boiler and
chiller. How do I model this into eQuest?
Thank you.

Yehuda:
I surmise that all eight buildings are on the central plant with the chillers
and boilers you describe. eQuest doesn't know that your 8 buildings are separate
buildings, just more zones. I would describe your zones (in the Detailed Edit
mode) such as "Building 1-North Zone" or "Building 8-Lobby" and put all the
zones on one massive CHW and HHW loop.
You can also make these loops Secondary loops, if the Central Plant has its own
loops.
Have fun !!

Thank you for your help.
I have a question on what you said. The boiler and chiller that service the eight buildings are extremely big. Anyway I have to start the model in the DD Wizard. If I make eight different shells and show seven buildings without a boiler or chiller, it seems that I could
Yehuda:
Yes, you certainly can have those seven shells. But you will also have the
eighth shell where the central plant is. eQuest does not care where the plant
is, but what is connected to it. Do no concern yourself with where the plant
resides, but what is connected to it.
BTW, does the plant have its own electric and gas meters? You can worry about
what meters go to what buildings in the Detailed Edit Mode, if you are trying to
match bills.
This sounds like an interesting project, such as a campus or hospital complex.

Supplementary to John?s advice, you should take advantage of a new feature in 3.64 that lets you assign a prefix to the components of each of your shells to make your model more easily manageable in detailed.
If you have a ?building A,? then you could clearly organize its generated zones/surfaces/schedules etc. by giving it a prefix of ?BA,? for example (on the first DD shell screen, iirc). For a hands-on example of this feature, seek out an eQuest importing guide I posted in the archives ;).
