1. A common wall between the zones Zone 1 with four walls and four windows Zone 2 with four walls and four windows An example of a model with two zones

2. This is the ORIGINAL wall BLOCK The common wall between the zones is constructed from an ordinary ’wall block’. Take an ordinary wall block from the library and look behind the block mask – see the example below The block should be replaced by one of this kind

3. NEW BLOCK – a common wall between two zones INTERIOR WALL CLADDING 1 replaces EXTERIOR WALL CLADDING Inputs Zone 1 and Radiation 1 replace Geometry

4. NEW BLOCK INTERIOR WALL CLADDING 1 is a copy of INTERIOR WALL CLADDING 2, with one new output – Last node. New Construction output

5. Last node.

6. CHANGES IN THE MAIN BLOCK MASK

8. Define material 1 in the block mask of INTERIOR WALL CLADDING 1

9. Go one level below and define surface transfer coefficients alfacin1 and betaPin1 in the block mask of Internal surface node /CTH. Check the names of the parameters with the ones specified in the main block mask (see slide 6)

10. Do the same for the block INTERIOR WALL CLADDING 2 / Internal surface node /CTH. Check the names of the parameters with the ones specified in the main block mask (see slide 6)
