Hero has a variety of Ceilings Assemblies that can be used, and these are visible within the Construction column of the Ceiling Data-Grid. The current Assemblies include assemblies of the following Types:

• Flat/Skillion Types: No Significant Roofspace Air Zone is created between the Internal Ceiling & the External Roof.

• Attic Types: Ceilings where a sizeable Roofspace Air Zone would be created between the Internal Ceiling & the External such that it deserves to be Simulated

• Slab Types: Ceilings with a Concrete Roof of various sizes. The Ceiling Insulation of

• Ceiling Types: Used for Internal/Neighbouring (both Actual & Manual Neighbouring Adjacency Types) to Simulate a Ceiling where there is only a Plasterboard Ceiling between the Ceiling & the Neighbouring Adjacency Above. See below Internal Floor/Ceiling Construction section.

Ceiling Data-Grid Assembly Column

In addition to the Construction or Assembly of the Ceiling, the Ceiling 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.

Ceiling Data-Grid Type Column

A Ceiling has two Insulation Options, Ceiling & Roof, that are positioned accordingly within the Assembly. This feature was implemented to enable flexibility & rapid design changes to both common Insulation locations within the Hero interface.

The Ceiling Insulation Option is the Insulation Material(s):

• below the Roofspace Air Zone for Attic Assemblies,

• below the Slab for Slab Type Assemblies

• the lower section of Flat Assemblies

The Roof Insulation is the Insulation Material(s):

• above the Roofspace Air Zone for Attic Type Assemblies

• above the Slab for Slab Type Assemblies

• the upper section of Flat Assemblies

Ceiling Data-Grid Ceiling Insulation Column

The Roof Insulation of the Ceiling. See above Ceiling Insulation section for details.

Ceiling Data-Grid Roof Insulation Column

For raked or sloped ceilings within a Zone, the Pitch can be entered in degrees.

This is the Internal Pitch of the Internal Ceiling Layer of the Ceiling, and not the pitch of the External Roof. The Pitch of the External Roof of a Ceiling is set by Hero automatically and cannot currently be adjusted.

The Pitched Area of a Ceiling is shown in the Data-Grid Area column in square metres and represents gross area not accounting for any Skylight area.

The Area is the Pitched Area, in that any Pitch entered in the Pitch column will automatically adjust the 2D Area of the Ceiling to account for the increase in area by any slope or raked Ceiling.

Ceiling Data-Grid Pitch Column

The Pitched Area (see above) of the Ceiling in Square Metres. Can only be adjusted as the Ceiling is moved & adjusted within the Visual View.

The External Colour (and it’s associated Solar Absorptance) of a Ceiling can be selected within the External Colour column of the Ceiling Data-Grid.

The Adjacency Type of the Ceiling (see below for full details)

Ceiling Data-Grid Adjacency Column

Ceilings with a Roofspace Adjacency can toggle the Ventilation Rate of that Roofspace Zone through the Ventilation column of the Ceiling Data-Grid.

Roofpsace Zones & Ventilation Rates are described in further detail in the Zones section.

Ceiling Data-Grid Roofspace Ventilation Column

The Ceiling is directly adjacent to External Environment.

This Adjacency Type is used for Flat Roofs where no Roofspace is present between the Ceiling & the External Environment.

If Adjacency Type is changed to External within the Ceiling Data-Grid then the Assembly, Type and potentially Insulation may change as appropriate for an External Adjacency.

Ceiling Data-Grid Adjacency Column

The Ceiling is adjacent to a Roofspace Zone.

This Adjacency Type is used for Attic Roofs where a large air volume is created between the Ceiling & the External Environment.

If Adjacency Type is changed to Roofspace within the Ceiling Data-Grid then the Assembly, Type and potentially Insulation may change as appropriate for an Roofspace Adjacency.

Ceiling Data-Grid Adjacency Column

Ceilings adjacent to a Floor from the same Dwelling

Cannot be changed in the Data-Grid

Ceiling adjacent to a Floor from a different Dwelling.

Neighbouring Adjacency Types are simulated as Adiabatic boundaries in the Simulation meaning that no effective heat transfer is modelled between them.

Cannot be changed in the Data-Grid

Ceilings adjacent to a Conditioned Space that is not part of the Hero Project model (i.e. Adjacent Buildings, Commercial Spaces etc).

Neighbouring Adjacency Types are simulated as Adiabatic boundaries in the Simulation meaning that no effective heat transfer is modelled between them.

Ceilings adjacent to an actual Carpark Zone that forms part of the Common Area Dwelling

Ceilings adjacent to an actual Corridor Zone that forms part of the Common Area Dwelling
