Sometimes it is necessary to create a smaller zone such as an office within a larger zone (e.g. a large warehouse space). This tutorial explains how to set up a simple 2 zone model such as that illustrated in the screenshots below where a small office is located in bottom corner of a larger warehouse space.

 

The steps involved are:

 

1. Draw the ground floor block including both office and warehouse. The block should be the height of the office space as the top of the block will form the ceiling of the office.

 

 

 

2. Draw the 1st floor block representing the high-level warehouse space.

 

 

3. Navigate to the warehouse space in the ground floor block and set the "Virtual ceiling part" property to Yes

 

 

4. Merge the high-level warehouse space with the warehouse space of the ground floor block

 

 

 

5. The 'floor' on top of the office zone is not usable floor area so it must be excluded from total zone floor area. To do this set the "Unoccupied floor area" property of the merged high-level warehouse space to Yes. This indicates that the floor area if the merged space is not part of the building useable floor area. This step ensures that this floor area is not counted in the floor area provided to certification tools such as SBEM.
