[bldg-sim] Question about simulation in equest

[Smita Chandra]

Dear Gary Zeng,

Usually you can simplify the wave into a few rectangles/trapezoids.  A few 
degrees difference in tilt will not affect your results to any significant 
degree.  What matters is (1) the tilt of the roof surface, and (2) the 
surface area of the roof; the first affects solar gain, the second heat 
transfer.  As long as your simplification matches these two criteria 
reasonably well, your results should be reasonable as well.

Sincerely,
Smita

Dear guys:
now I am using equest3.5 in a energy simulation project.A big barrier is 
the wave shaped roof,whicn i did not know how to model it. I would like to 
know how i can create a simulation model in equest or other visual tool 
like VisualDOE.
it is urgent to me and any help is greatly appreciated.
u can reach me directly by zeng-yi at etang.com or reply this message.
