Re: [EnergyPlus_Support] zoning

[kir kumar <kirank209@xxxxxxxxxxx>]

Dear Linda,  
I read the documentation you mentioned about zoning,
but still that does not solve my problem.
Actually I want to calculate two things.

1.Energy consumption of the entire 7-storey
building(each storey with 2 air handlers and each air
handler takes care of approximately 14 rooms(all rooms
are at same set point temperature) and each room with
its own air terminal unit(SINGLE DUCT VAV REHEAT)).
2.Energy consumption of space in the third storey
which is being taken care by an air handling unit.

In E+ documentation of energy plus university course,
I read that  spaces to which an air terminal unit(VAV
single duct reheat) is attached must be considered a
single zone. In that case I am afraid that I have to
consider each room to which an air terminal unit is
attached as a sinle zone which makes my input file
quite complex. 
Please help me in zonning this building.
thanks in advance

Putting "zoning" in the search leads to a good article
in Gettting 
Started (page 31 of the PDF).

There are several philosphies about zoning, there is
not necessarily 
a "right" answer.  For example, if each story has a
large floor area, 
you may want to zone it with perimeter zones and a
central/core 
zone.  (Our "5Zone" example files illustrate this).  
On the other 
hand, you may be able to zone each floor as a single
zone.  The 
inaccuracies introduced are discussed in the section I
mentioned in 
GettingStarted.   And you may be able to use
zone/group multipliers 
so that you would only have to describe one interior
story and the 
exterior/roof story.

It does depend a lot on what kind of answers you want
from the simulation.
