Bill/Luke:

 

Thanks!  I felt certain this was there but I guess my eyes were
selectively screening that line for some reason J.

Nick,

 

ASHRAE Standard 90.1, 2004, Appendix G., p.172, "The [baseline] building
shall be modeled so that it does not shade itself." (P. 178 in
90.1-2007.)

 

Regards,

Bill

Luke,

 

1.       Concur!

2.       First - wow, I never noticed this input... but I'd like to
guess at your intent and have a 90.1 question.  I flipped open my 90.1
2004 & 2007 to find the passage where it says "baseline models shall not
be self-shading..."  and I can't seem to find it =/.  TG3.1, section 5
for building envelope seems to only mention shading projections being
excluded in baseline models.  That said, I'm certain I first picked up
the term "self-shading" somewhere within 90.1... am I incorrect in
thinking/hoping all baseline envelope constructions should have their
"Shading Surface" field set to "No?"

Equest-users,

 

After playing around with my model for a while, I think I can answer my
own questions.

 

1. You can model these surrounding buildings as "Building Shades" in
detailed mode.

2. You can turn off/on whether an external surface is a "Shading
Surface" in the spreadsheet view of Building Shell.

 

Thanks anyway,

Luke Wilson

Hello,

I have two questions.

1. If you have a building with other buildings modeled in close
proximity, does equest take into account the shading from the
surrounding buildings?

2. Are equest models self-shaded and if so can you turn this feature
on/off?

 

Thanks in advance,

Luke Wilson
