[Equest-users] External Shading and Self-Shading

[Wilson, Luke]

Nick,
Thanks for your response.
If you look closely in Table G3.1, section 5 a. orientation for the Baseline Building Performance, it reads, "The building shall be modeled so that it does not shade itself".
Appendix G doesn't use the exact phrase "self-shading", but it's the same thing as far as I can tell.

Thanks,
Luke Wilson

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
