The Floors of a Zone are distinct from the Ceilings of the Zones Zone even if they share similar geometry & many features.
...
Floors are also Split Automatically by Hero when any adjacent Ceilings are detected on the Level below. This can occur after a new Zone has been created or when Floors or Ceilings are moved.
| 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.

Assembly | Hero has a variety of Default Floor Assemblies that can be used, and these are visible within the Construction column of the Floor Data-Grid. The current Assemblies include assemblies |

Type | In addition to the Construction or Assembly of the Floor, the Floor Data-Grid also contains a Type column that is used for reference & information but that if changed may change both the Assembly and Adjacency Type to the relevant defaults for that Type as required. See above Assembly row for details. |

Insulation Option | The Insulation (if any) can added to a Floor via the Insulation column of the Floor Data-grid. There are variety of Floor Insulation Options available depending on the Floor Construction, including: Slab on Ground Assemblies: Several common R-value underslab insulation products. Waffle Pod Assemblies: Various thickness of EPS-foam waffle-pod void formers that lie below the slab. The R-values are the thermally bridged R-values that account for the concrete ribs or beams across the floor. There is also a uninsulated option in the list for non-foam based waffle-pods such as plastic void formers etc. Suspended Floors: A variety of Insulation options that represent common insulation systems including:

Slab Edge Insulation | Concrete Slab on Ground & Waffle-pod Floors can have Slab Edge Insulation added to them via the Slab Edge Insulation column in the Floor data-grid. There are a fixed variety of typical R-value products that can be selected for the Floor.

Floor Covering | Floor Coverings are used to model the effects of various materials on top of the 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 |

Floor Adjacency Types

Adjacency Type
...
Description
...
Similar to Walls & Ceilings, Floors have a variety of different adjacency conditions that are determined by whether the
...
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.
Floors of a ground-type such as Concrete slab or Waffle-pod assemblies have a GROUND adjacency type and if the adjacencyAdjacency Type | Description | Editable Within Data Grid |
|---|---|---|
Ground | The Floor is directly adjacent to Ground such as for a Concrete Slab or Waffle-pod Assembly. If the Adjacency type is changed then the |
Assembly will be automatically changed away from a Ground type |
Assembly. | Yes |
Subfloor | Floor is adjacent to a Sub-Floor Zone. When a Floor has a Subfloor Adjacency, Hero will automatically create a |
|---|
Subfloor Zone underneath the |
Floor, or if a |
Subfloor Zone already exists on that |
Level, will expand the |
Subfloor Zone to encompass the area below the newly changed |
Floor. Subfloor |
Zones are detailed further in the Zone section of this tutorial and have many special properties. | Yes |
External | If the |
|---|
Floor is sufficiently elevated such that the area below it does not form a |
enclosed or semi-enclosed Sub-Floor Zone, then the |
External Adjacency Type should be used. This represents a |
Floor that is simply adjacent to the External environment temperature (i.e. outside air). | Yes | |||
Internal | Floor adjacent to a Ceiling from the same Dwelling | No | ||
|---|---|---|---|---|
Neighbouring (Actual Connection) | Floors adjacent to a Ceiling from a different Dwelling.

Neighbouring (Manual Selection) | Floors adjacent to a Conditioned Space that is not part of the Hero model (i.e. Adjacent Buildings, Commercial Spaces etc).

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.

Roof-Space Soffit Floors
When a Ceiling has a Roof-space connection Space Adjacency such as from formed by an Attic assembly Assembly type, then a special Soffit floor Floor will be automatically created for the roofspace Roofspace and will become visible in the Floor Data-Grid tab. These are discussed further in the Roof-space Zone section.
