The floors Floors of a zone Zone are distinct from the ceilings Ceilings of the zone, Zone even if they share similar geometry & many features.
A Floor is created automatically when a zone Zone is drawn and might be automatically split and connected to any ceilings on levels below on creation.

Floors can also be selected within the Data-Grid within the Floor tab.
Floors share the select parent context Select Parent Context-menu item similar to most objects , or the double-click (or it’s 🖱 Double Left-Click mouse shortcut). In this case, the action selects the parent zone Zone of the floorFloor.

Geometry
The area of a floor is shown in the data-grid area column in square metres and represents gross area prior to the removal of any Hole area.

Splitting Floors
Floors can be split Split into separate floors Floors within a zone Zone through various means.
Firstly they can be split Split manually by the user using the Split Drawing Mode feature (which is dealt with in a separate section of this tutorialSplit & Merge Drawing Mode). This is typically performed when the floors Floors across a zone have differing properties such as floor coverings, or insulation or adjacency. For example, in this project shown, we have a floor where the kitchen & living area form one single zone, however the floor covering changes from tile to timber etc etc. Assembly or Construction, or Insulation or Floor Covering or Adjacency.
Automatic Splits
Floors are also split automatically Split Automatically by Hero when any adjacent ceilings Ceilings are detected on the level Level below. This can occur after a new zone Zone has been created or when floors Floors or ceilings Ceilings are moved.
Offset Points (adding/deleting/how they move)
Floors can have points added to their polygon .
| Note |
|---|
Hero’s Automatic Splitting Feature is a very handy tool that removes the requirement to manually split and connect adjacent spaces. However there are occasions where manual User adjustment or overriding of the adjacency & other construction properties (assembly & insulation) of automatically split Floors & Ceilings is required after a split. For example in the image below, a Zone’s Floors have been split into 3 Floors with 2 adjacent Internal connections to Ceilings below, but also a third Floor “FLR 05” which has an initial default adjacency of “Ground” and Construction “CSOG-100” which is inappropriate. In this example, the User would be best to set FLR 05 to Neighbouring Adjacency which will then trigger a Construction change & update too, as this section has an Adiabatic Adjacency condition that should be ignored in a Chenath simulation (e.g. no temperature difference, only internal mass of materials). |
...
Offset Points
Floors can have Points added to their polygon shape after they’ve been created.
To do so, right🖱 Right-click Click near an edge of a floor Floor (not clicking a wallWall) and select the Add Point action.
This will add a floor point Floor Point at the location as well as to any adjoining floorsFloors, and to any ceilings at Ceilingsat that location if appropriate.
These points Points are not shared with any wall points…if Wall point, if you desire to add the point to a wall Wall point as well as a floorFloor/ceiling Ceiling point then you should use the Split Wall feature.
These floor points Floor Points can be deleted by right clicking 🖱 Right-Click them and choosing the Delete Point action. If the point Point can be validly deleted while keeping the floor Floor polygon regular, then the point Point will be deleted.
These floor points Floor Points are also created when floors Floors are automatically or manually split by Hero.
...
Moving:
Floor points Points can be moved around by left-clicking & dragging the floor pointswithin the Visual View by 🖱 Left-Clicking & Dragging the Floor Points. If there is a ceiling Ceiling Point sharing this pointPoint, it will also be moved. Similar to many move Move actions, holding shift ⌨ Shift-key while moving will lock the move in a straight horizontal ↔ or vertical ↕ direction.

There is also an Exposed Floor Covering which denotes no real floor covering. This option is only available for slab floor assemblies.

Internal Floor/Ceiling Construction
When a floor has an adjacent ceiling below it, such as on a two-story dwelling, or between two apartment dwellings, the full material buildup for the assembly is determined by both the Floor & the Ceiling’s properties.
An internal ceiling can only have a plasterboard ceiling or exposed ceiling assembly applied to it; and the internal ceiling will not be able to have Insulation applied to it in the Data-Grid. If this internal floor/ceiling is to be insulated, the insulation gets applied to the floor above. The complete material build-up that will be simulated is the Floor Covering followed by the Floor Assembly followed by any Floor Insulation followed by the Ceiling Assembly below.

Floor Assembly within a Simulation. The Floor Coverings have slightly different Materials depending on whether they are applied to a Suspended Timber Floor or not. See the Floor Covering Table below for further details. | Covering Column | |

Floor Adjacency Types
Similar to Walls & Ceilings, Floors have a variety of different adjacency conditions that are determined by whether the floor Floor is adjacent to actual model objects or that can be selected manually be the user.
Floors that are adjacent to a Ceiling from the same dwelling, will have an Internal Adjacency type, and this adjacency type cannot be changed in the data-grid.
Floors that are adjacent to a Ceiling from another dwelling will have a Neighbouring Adjacency type, again this cannot be changed in the data-grid. Neighbouring adjacency types are simulated as adiabatic boundaries in the simulation meaning that no effective heat transfer is modelled between them.
Floors that are adjacent to a Carpark or Corridor zone will have a Carpark or Corridor adjacency type selected which again cannot be changed.
For floors that are not adjacent to another ceiling below, then there are a variety of adjacency types that can be manually selected by the user to model specific conditions.
...
Adjacency Type | Description | Editable Within Data Grid |

Subfloor Zone already exists on that |

Level, will expand the |

External | If the |

Floor is sufficiently elevated such that the area below it does not form a |

Floors with a Subfloor adjacency can toggle the ventilation rate of that subfloor zone through the Ventilation column of the Floor data-grid. This is described in further detail in the Subfloor Zone section.
