[Equest-users] Zones with different roof height on same floor

[David Griffin II]

Tejas,

Great question! I work for an architecture firm as an energy analyst, and I find my life is a lot easier if I go the extra mile to accurately model the building’s envelope in eQuest despite the extra time and effort with a mild increase in accuracy. I have illustrated one of my recent models below which includes green screens, parapets, a partially sloped roof, and spaces with and without ceilings (a lot of overkill). This process is much more involved than the process your model will take. See my step-by-step instructions below.

It appears your model will require at least three (3) shells be created in the Wizard – One for portion of the building.


1)      Create first shell with height ‘X’

a.       All shells should have the footprint of the entire building.

2)      Create second shell with height ‘X+N’

a.       All shells should have the footprint of the entire building.

b.       On the ‘General Shell Information’ screen (1 of 26), make sure you ‘Specify exact Site Coordinates’ in order for eQuest to appropriately assign geometry and locate the shell accordingly.

3)      Create shell with height ‘X’

a.       All shells should have the footprint of the entire building.

b.       On the ‘General Shell Information’ screen (1 of 26), make sure you ‘Specify exact Site Coordinates’ in order for eQuest to appropriately assign geometry and locate the shell accordingly.

When you are done, you should have something that looks like the following illustration. If you have done it correctly, the wizard should create all your interior and exterior walls appropriately as illustrated by the outlined geometry (Red). Of course, I encourage you to add thermal zones as required to each shell to accurately model the HVAC system and other associated loads.

Subject: [Equest-users] Zones with different roof height on same floor

Hi all Modelers,

This time I have come across a single floor building which has zones with different height. I have attached a roughly drawn elevation as an example (Which is not needed :/) . Can any1 guide me how to model such case as equest allows you to take same height for single floor.

Thanks,
Tejas
