[BLDG-SIM] Building additions and shading

[Vikram Sami]

I am guessing you want to model the buildings without shading for the
LEED base building. You can model the adjacent buildings as exterior
shades that mimic the building geometry. You can set the shade
transmittance and control the shading from that, or just reduce the
height to be near zero (I don't think you can actually use a zero value)
 
With regards to self shading, there are a few posts earlier on this list
serve that address that.
 
Hope this helps.

Kevin,

 

I have interpreted the existing buildings to be perpendicular to the
addition.  If this is the case and the buildings at the ends of the
addition are large, they could produce significant shading on the
addition (especially if the exposed surfaces of the addition face north
and south).  The problem is: how do you quantify this?  More than
likely, you will have to create a schedule to represent it if you don't
model the whole building.

Kevin:

 

I am getting a bit old and slow, so I don't quite understand your
questions.

 

If you are modeling a new construction rectangle that has both ends (say
top and bottom on a plan view) abutting existing structures, I believe
you can make these walls INTERIOR and ADIABATIC. In that way, you have
no outside influence on the wall, and no heat transfer to another space.

 

You WILL, however, need to make the changes in the .INP text file. You
simply cannot do it in the eQuest overlay.

 

Why do you care about shading from external sources. Just don't put
those sources In !!

 

Or have I missed something?

Greetings, I am simulating a building that from bird's eye view looks
like a big rectangle.  Either end of the new construction is connected
to existing buildings.  Furthermore, it appears the first floor of the
new construction extends into a renovation of one of the pre-existing
forms.  How does one turn off shading on exterior surfaces?  Also, would
it be better to modeling the existing buildings as well?  The new
construction will be running on its own systems.

 

Thanks.

 

Kevin
