Even better would be to learn how to add/delete roofs in the DD edit mode so that you don't have to go through any gyrations. It's not that hard to do. It's something that I teach people who do classes on line with me. Let me know if you are interested.<br>

<p class="MsoNormal"><span style="color: rgb(31, 73, 125);">Another option is to save your
model with a diff name, go into the wizard of your new model and create two
zones, one for the area below the second shell and one more for the surrounding
area. Set the HVAC system to create a system per zone so the program will
automatically create two plenums and associated roofs. Set mode to detailed, copy
the two plenum zones, spaces (and associated walls and roofs), and polygons
from the new model and replace the plenum in your original model with the new
plenums once the original model is in the detailed edit mode. Then, delete the
roof of the plenum under the second shell.</span></p>

<p class="MsoNormal"><span style="color: rgb(31, 73, 125);">This only works if your original
model has plenums, and only one plenum per floor. If you have a simple shape
or only a few zones, this may be over-kill. But, if your footprint has a lot
of vertices or you have a lot of zones that would otherwise need to be broken
up, this method may be a time saver.</span></p>

<p> One way is to make the zoning on the first floor line up with the
second floor foot print. This I think, is the best way if the second
floor is a complex shape. The addition of a roof or it's deletion can be
geometrically tricky to do if it spans only part of a zone. I have found
lining up the zones with the foot print an easier solution. You may have
to add a few extra zones to get the matching shape. You delete the roof
under the foot print. If the zoning doesn't match your HVAC zones you can
adjust the zone grouping so that it does. Turn any interior walls into
air walls if they don't actually exist on the first floor. You may also
have to adjust or delete the floor of the second story as the ceiling of the
first floor is floor of the second floor. Check through your layers to
make sure they are consistent with the actual construction. Make sure
your boundaries are referencing the proper adjacent zones. This is the
technique, and may not exactly match what you are doing, you will have to check
through everything to make sure everything is consistent.<br>

<p class="MsoNormal"><span style="font-size: 14pt;">I have 2-storey building. The
1st storey in a plan is not like the 2nd one. That’s why I created 2
shells (one above the other). For the 1st storey I have created a roof (because
part of a ceiling is outside the building). And for the 2nd storey I have
created a floor. Parameters of the roof of 1st story and the floor of the 2nd
story are different! During the calculation the eQUEST will calculate Heat Flux
through the ceiling/floor. </span></p>
<p class="MsoNormal"><span style="font-size: 14pt;">How eQUST calculate it if
ceiling of the 1st storey is not the same as the floor of the 2nd storey?</span></p>
<p class="MsoNormal"><span style="font-size: 14pt;">If air condition in 1st and

different - this question is very actual!</span></p>
