Underground spaces simulation

Post by shaibani »

I am working on my thesis, which requires me to do simulation on the underground spaces. If I calculate the soil temperature via LAB equation and soil temperature profile obtained, in this case how can I simulate the underground space and where to inter soil temperature?

Hi,

You can define walls and floors as being below ground level by editing their adjacent condition. Do this in a thermal view (Apache or VE Compliance) by selecting a room then go down through the levels of decomposition until you select the surface you want and then query the surface so you can edit the "Adjacent Condition" dropdown or select a room and use the "Edit Multiple Adjacencies" button to change all Ground Floors or Walls at the same time.

When the Adjacent Condition of a surface is set to "Outside air with offset temp" or "Temp from profile" the surface is treated as being underground.

You can then create a new profile to use as the adjacent condition if you require more detailed analysis.

Hi again,
Would you please more elaborate regarding the temperature from profile and this profile is for the whole year or on day, I am sorry but I have no idea about the profile.
Thanks

sorry but I don't really have that much time to go into detail about profiles in VE on this forum - you can access the Profiles Database via Building Template Manager or and of the Thermal/Compliance applications in VE.

In this instance you can create a new Daily Absolute profile to represent the soil temperature at timed intervals during a day (how accurately you want to model this is up to you, I would guess hourly would be as far as you'd want to go though). You then create a weekly profile and assign daily profiles to each day and finally, if required, an annual profile referencing the weeks.

I think this is the way you want to model this but I don't know if anyone has done anything like this before
