[Equest-users] boiler and chiller serving multiple buildings

[Nick Caton]

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 ;).

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.

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:

 

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 !!

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.
