I am modeling a fully glazed building with inclined walls. In fact, the
building envelope is in the form of a globe or like a sphere. Can anybody
suggest how this can be modelled in equest.?
Critical details aside, I expect constructing a full 3D globe in eQuest
would be a pretty major challenge for most of us. I've done some
complicated curvilinear 3D shapes in the past (isolated helical building
shades and similar), but those efforts required much time absorbing all
the math involved in describing that shape in order to produce formulae
in a spreadsheet to generate the correct polygon vertices and format
them in a fashion such that they may be copy/pasted or imported into an
.inp file.
Achieving a full globe would likely require a different approach -
perhaps a geometrical import via green building studio or referencing a
3D model while defining each facet polygon in detailed mode... I'd
personally ask around to see if others have tread a similar path to see
if it seems feasible first.
Thanks for your inputs...yes, this seems a major challenge. I was thinking
of creating a dummy floor in between (with 'open to below') and give
inclined facades..but I doubt if there are any options in eQuest for
inclined or angled facades..in between I read from one of the forums that it
can be done in DD Edit...!!! still trying to find ot out, any idea if that
option is available in eQuest..?
And yes, I need to try it GBS and IES too....I would also like to see
anybody here in our community has done similar models with slanted
facades/spherical structures etc....
You can adjust the angle of exterior wall and roof surfaces by changing
the Tilt in DD Edit mode. Don't worry about the fact that it looks like
there are truck-sized holes in the building.
Anoop,
If you are modeling against an energy standard, be sure to check when your inclined "wall" becomes a "roof". In 90.1-2007 a roof is "horizontal or tilted at an angle less than 60 degrees from horizontal".

Not easily.
