[Equest-users] eQUEST Roof Question

[Sami, Vikram]

The way to do what John described:


1.       Create custom polygons in the detailed interface and apply it to the roof shapes

2.       Easier, but could be troublesome: in the wizard you can define the areas under the building above as separate zones – define the wall in between as air. This makes it a lot easier to assign ceilings to the interior spaces and roof to theexterior ones.

Sunayana:

It appears your 2nd model IS modeling the roof correctly. The portion which is beneath the upper floor in the corner should only have ceiling, not roof.

Subject: [Equest-users] eQUEST Roof Question

When upper floors of a building are not superimposing the lower floors, how is the exposed roof area situation modeled in eQUEST?
If I select “No exterior Exposure (adiabatic)” in roof construction at wizard stage, it will delete the whole upper layer of the roof as in the below image (left) and if I select exposed roof construction type at wizard, it will lead to overestimation of exposed roof area as in below image (right).
Please let me know the best way to model exposed roof in this situation. If I go for separate building shell specifically for roof, will the model be correctly taking into account the conduction through exposed roof area?
Any comments will be appreciated.
