[Equest-users] Building Geometry

[Singhal, Harshul]

Hi Maria,

We have done one university block recently which had 2.5 feet thick walls (retrofit) and we modeled using inner dimensions. Whether it’s thick or thin, its advised to use inner dimensions although project requirements vary sometimes. Thanks!

Does anyone have experience with modelling thick-wall retrofits who can also answer my question?
It is a small house, so if I trace the interior dimensions I will get significantly different results than tracing exterior dimensions

As far as I know, it goes in.

Hello,

It is a low-energy retrofit and the walls are really thick!
My fear is that by using the outside dimensions, then if the wall contruction goes 'outward' of these defined lines, then I am modelling a larger house ( the volume of the house in the model is greater than the actual volume) .

please help :)!

thanks,

maria

It should not make that much of difference unless your walls are rally thick.   I suggest you trace the outside wall and then make sure of the wall thermal properties.

Hello,

Can someone please help me with this:

I have an AutoCAD file of an old home that was retrofitted with thick (insulated walls). When I import this file and trace it to define the building footprint on eQuest,should I be tracing the OUTSIDE of the building (the brick face) or the INTERIOR of the building (the interior walls)? or should I draw a line in the middle of them and use that as my building footprint?

do you know the wall construction goes INWARD or OUTWARD from the building footprint you set?

thanks,

maria
