I am modelling a building and I have some thermalzones with equipments and thermostats and others without both.

My problem is that few spaces without any equipment are being reported as conditioned and becuase of that the conditioned area of the building is incorrect.

I have already tryed to put an equipment on the thermalzone and then remove it, but it did not work. Also tryed to turn on enable ideal air load and then turn it off, but also did not work.

Another thing is triking me is both tables: Building Area and EAp2-1. Space Usage Type , both on OS HTML report. How is it possible for the building to have an área of 8725m² which 4860m² are unconditioned (accordint to table EAp2-1. Space Usage Type and 6328m² of conditioned area and 2396m² of unconditioned building area according to table Building Area??

Building Area Table Building Area Table

EAp2-1. Space Usage Type Table

Any idea on how to solve it?

Thanks a lot.

Do the unconditioned zones have thermostats? If so, try removing the thermostats.

They do not have neighter thermostats nor equipments.

I have no idea what happened to my simulation. The thing is, when sum up all unconditioned spaces in a spreadsheet, happens to be 2396.25 and it is the same as in building area table.

I do not know whats is happening, but the EAp2-1. Space Usage Type is the one wrong.

If the numbers are right in the Building Area table, then they are wrong in the EAp2-1 table. Send your E+ input file (*.idf) to so this issue can be resolved.

In version 9.1 the EAp2-1. Space Usage Type table shows the same area as the Building Area table at 6328.86 m2 and 2396.25 m2 for Regularly Occupied and Unconditioned Area respectively. I suggest getting the latest version to correct the EAp2-1 Space Usage Type table result.
