<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>I think what you have done will work, but
you’re not finished yet. The geometry within geometry is not ignored. You
can verify this several ways. For example, the floor area of the sloped-roof
space is probably identical before and after adding the “brick”
dormer. The conduction loads to the space are probably identical. The solar
load, however, may be reduced due to shading by the dormer shell.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Another thing you should check is whether
or not the area “inside” the sloped roofs is conditioned or not
(and that you don’t just have a 1’ tall conditioned space). The
last project I did with sloped roofs, eQUEST generated an unconditioned “Under
Roof” space with all the roof surfaces assigned to it. If the conditioned
volume checks out, I think you need to make the following
additions/modifications:<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>1.) Modify the floor polygon of the
sloped-roof space to subtract the area of the dormer.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>2.) Modify the roof polygon to subtract
the dormer.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>3.) Add an interior wall, air-type, for
the long “geometry-within-geometry” wall, NEXT-TO the sloped-roof
space.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>4.) Delete the exterior wall that the
interior wall replaces.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>5.) Modify the other two exterior walls.
Make them triangles by creating new polygons.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I am attempting to model the roof & top floor of my
building. It is a 12/12 roof with intersecting dormers and a flat section
of roof. There is no magical way to make this happen from what I can
tell. I wish there was a “easy button” like in those
commercials! My best solution so far has been to create a
1’ tall wall & build a 12/12 roof on it. Rather than build the
roof on my 3<sup>rd</sup> floor, building the 1’ wall allows me to apply
my w/sf and occupancy densities for that 1’ wall floor area. To
represent the dormers and protruding geometry I plan on modeling intersecting
shells. Is there any issue with this method? See below the image of
the dormer and then the X-ray image showing that the brick shaped block
representing the dormer. The block has geometry extending into the
conditioned space. It this an issue? Is geometry within geometry
ignored in eQUEST? If anybody has any dormer modeling methods, I would
greatly appreciate some tips! <o:p></o:p></span></font></p>
