[Equest-users] Different roof and floor.

[Otto Schwieterman]

I have found that this option is very helpful when creating sloped roofs (sometimes the architect is not happy until the building model looks exactly like the building).

I haven't played with 3.64 much yet do to ongoing projects, but I did notice this.

I also ascribe to the method of deleting redundant roofs post-wizard...

 

On a related note - I recently noticed the option to define distinct roof/wall constructions in the wizards for each zone within a single shell (this may or may not be new to 3.64?)...  The pull-downs for this are in the second shell DD wizard screen after clicking the zone characteristics button.

 

Has anyone played with this?  If it's possible to define zones with/without roofs in that visual interface that may be a more time-efficient method than doing it post-wizards, and particularly useful for those "wizard-bound" studies that are necessary sometimes due to time constraints.  It's something on my to-do list to explore, but I'd like to hear if anyone has used this feature successfully for such a purpose =).

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.

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.

 

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.

I always use the roof and floor designation in the wizard of below conditioned space and over conditioned space.  And then any area that is not directly under the second floor I make it a separate shell with the appropriate roof.  I suppose either method would work, but if you have a lot of spaces it could become tedious having to go through the construction of each one individually.

  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.

Hi

 

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. 

How eQUST calculate it if ceiling of the 1st storey is not the same as the floor of the 2nd storey?

If air condition in 1st and 2nd story same, this question not so important, but if condition has big different - this question is very actual!
