[Bldg-sim] Modeling an Exterior Chase

[Nick Caton]

Agreed.

 

Tracing the footprint as you have - you are setting up flexibility to
revisit this decision later if you should desire to.  You could easily
come back and define an alternate layered construction to apply to the
associated exterior surfaces later if you need to enhance the model's
accuracy ;).  I also suspect the net effect is probably negligible.

I vote "Ignore it".  It's a small construction difference in a small
portion of the overall envelope and will not affect your overall results
at all, especially considering the myriad of other assumption you are
making.

Is it good modeling practice to model a small chase in a building if it
is on the exterior?  Should I simply add it to the space nearby or
create its own space and let it float and push the loads via heat
transfer to the interior spaces?  Does adding this little bit of detail
make enough difference?  See my attachment for a little view as to what
I am talking about.

 

Any help would be appreciated!
