In my building on the ground floor there are certain areas that are four steps lower than others. Giving a difference in FFL of around 0.5m.
How would I create a different floor level within the same floor?
Hi Kieran, It is quite difficult to model stepped levels on the same floor, but you can instead model this by simply treating both areas as having the same floor level, and then adjusting the Room Heights to take account for the change in room volumes.

You simply need to go into the Room Data menu for the room you want to change (in CAD Input, double click inside the room), and the Room Height setting is in the top left corner. Change this to the height required, then click the green tick.
In general, the most important geometrical factors to take into account to ensure accurate energy modelling of a room are:
1 - Surfaces areas (partitions, exposed walls, windows, etc.)
2 - Room volumes
In this case, altering your room height is to ensure an accurate room volume. You simply need to adjust your room height in accordance with how much the floor rises/falls in the room. Take, for example, the simple section view of two adjacent rooms:
This can be modelled in Hevacomp as follows:
