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.

FLOORS WITHIN THE DATA-GRID
Property | Description | Edited Within | |||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|
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 of types:
|
Construction Column | |
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. |

Type Column | |
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 Table below for further details. |

Sub-Floor Ventilation Type | Floors with a Sub-Floor Adjacency can toggle the Ventilation rate of that Sub-Floor Zone through the Ventilation column in the Floor Data-grid. This is described in further detail in the Sub-floor Zone section. |

Floor Adjacency Types
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.
Adjacency 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.
|
|---|
No | |||
Neighbouring (Manual Selection) | Floors adjacent to a Conditioned Space that is not part of the Hero model (i.e. Adjacent Buildings, Commercial Spaces etc).
|
|---|
Yes | |
Carpark | Floors adjacent to an actual Carpark Zone that is part of the Common Area Dwelling |

No | |
Corridor | Floors adjacent to an actual Corridor Zone that is part of the Common Area Dwelling |

No |

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