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:

Concrete slab on-ground types of various thicknesses

Concrete waffle pod slabs of various thickness.

Suspended timber floors, one unlined & one lined with fibre-cement sheet below

Suspended concrete floors of various thicknesses & lining.

And a suspended AAC or Hebel-type floor assembly

Note

Suspended Timber Floors & Timber Floor Coverings

It should be note that the Suspended Timber Floor Assemblies are referring to “Timber” only as the structural material and that it is the Floor Covering which determines whether the Floor has timber floorboards or not, not the Assembly.

Info

Floor Assemblies Lined Below

The Suspended Timber & Suspended Concrete assemblies that are “Lined Below” are for use when the Floor is suspended such as over a Subfloor Zone or over the External Environment, and are not to be used when there is an actual Ceiling from another Zone below as the Ceiling Material will be added already to the Assembly build-up.

Note
Changing the Assembly in the Data-Grid may change the Adjacency type of the Floor if required such as when changing from a Concrete Slab On Ground assembly which has a Ground Adjacency to a Suspended Timber Assembly will change the adjacency to Subfloor or External Adjacency depending on Level height, & vice-versa.

Info
Floors that have an adjacent Ceiling below them will not be able to change to a Ground type Assembly (such as Concrete Slab on Ground or Waffle Pod slabs) and in this situation these Ground Type Assemblies will not be shown within the drop-down of the Wall Data-Grid Construction column.

Note

Internal Floor/Ceiling Constructions

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 is to be applied to the Floor above.

The complete material build-up that will be Simulated is the Floor Covering + the Floor Assembly + any Floor Insulation + the Ceiling Assembly below.

Floor Data-Grid 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.

Floor Data-Grid 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:

No insulation: This would be used if the Floor was exposed directly below it such as a Timber Floorboard where the Floorboards are directly exposed & visible from underneath; or for a Suspended Concrete slab floor where the slab is exposed to the air directly underneath.

Non-reflective Air-gap: This would be appropriate for most common Internal Floors where between the Floor Covering and Ceiling below there is an empty air-gap (if uninsulated).

Batt Insulation Materials

Reflective Air-gaps combined with Bulk Insulation Materials: Appropriate to use to simulate reflective membrane insulation products such as Kingspan’s Permifloor, or reflective rigid EPS insulation products such as Foilboard, etc of various thicknesses & reflectivity.

Floor Data-Grid Insulation Column

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.

Note
Note Slab-Edge Insulation is applied in Chenath as a single property of the Ground Layer of the Chenath Simulation. Therefore the correct way to model Slab-Edge Insulation within Hero is to apply it to all Floors on the same Level rather than just to the perimeter Zone Floors.

Floor Data-Grid Slab Edge Insulation Column

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 Table below for further details.

AreaSubfloor

The Gross Area of the Floor in Square Metres (i.e. does not include Holes/Stairwell area)

Not Editable within Data-Grid

Sub-Floor Ventilation Type

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

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

Ground
The Floor is directly adjacent to the Ground such as 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.
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 adjacency type is changed then the assembly will be automatically changed away from a Ground type assembly.
Floors can have a Subfloor adjacency type, which when changed will automatically create a subfloor special zone underneath the floor, or if a subfloor zone already exists on that level, will expand the subfloor zone Floor Data-Grid Adjacency Column
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 floorFloor.
Subfloor zones ZZones are detailed further in the Zone section of this tutorial and have many special properties.

External
If the floor Floor is sufficiently elevated such that the area below it does not form a subfloor zoneenclosed or semi-enclosed Sub-Floor Zone, then the EXTERNAL adjacency type External Adjacency Type should be used. This represents a floor Floor that is simply adjacent to the External environment temperature (i.e. outside air).
