SHADING
Walls can have Shading Objects that can affect the way they are simulated Simulated, these include:
Screens: Being screened by up to 3 vertical shading Vertical Shading objects or Screens in front of the wall. This is detailed further in the Screen Model section.
Eaves: A single horizontal shading object or Eave over the top of the wall. This is detailed further in the Eave Model section.
Wing Walls (Left & Right): Shading objects projecting from the left & right edges of the wall.
| Info |
|---|
It should be noted that any shading Shading objects connected to a Wall likewise shade any Windows or Doors upon that wall Wall in a similar manner. |
Walls can be attached to Screens & Eaves using the Attach Screen and Eave Drawing Mode which is detailed further in Screen & Eave Drawing Modes. Alternatively you can also Attach a Screen or Eave to a Wall by accessing the 🖱 Right-Click context menu on a Wall and selecting Connect to Screen or Eave and then 🖱 Left-Click the desired Screen or Eave to connect the Wall to the Screen or Eave.
Internal walls and many other types of wall adjacencies Wall Adjacencies such as Neighbour & Roofspace adjacent walls Adjacent Walls cannot have any shading Shading applied to them.

INTERNAL/NEIGHBOURING WALLS WITHIN THE DATA-GRID
Adjacent Walls such as Internal Walls between Zones, or Neighbouring Walls between Zones of two different dwellings have several unique features in Hero.
When selecting Selecting an Internal Wall in the Data-Grid, if you have the Zone Group-By header button selected, the Data-Grid will show both sections of that wall Wall selected under each respective walls…these walls Zone. These Walls are the linked sections of each-other within each room Zone and basically represent the same object. Editing one of them within the dataData-grid Grid automatically updates the other as they are linked together into a single unit.While external

DIRECTIONAL INTERNAL/NEIGHBOURING WALLS
...
While External walls have the External Side of the Construction facing outwards, Adjacent Walls are Directional, in that the External & Internal Sides of the Construction (as shown in the Wall Construction Library) can be changed within the assembly.
For the default internal plaster stud-wall, which is a symmetrical assembly with plasterboard on each side & an air-gap or insulation in the stud cavity, the direction of the wall Wall is unimportant. However if the adjacent wall assembly Wall Assembly is non-symmetrical, you can ensure the correct direction of the assembly Assembly by the Direction arrow Arrow on the wall Wall in the Visual View. The arrow Arrow points towards the “External” “External” side of the Assembly (as per the Wall Construction Library). If the direction needs to be changed, you can flip Flip or reverse Reverse the assembly by clicking 🖱 Left-Clicking the Direction Arrow within the Visual View.
Modelling the correct direction of a wall Wall is particularly important where the wall Wall has a heavy thermal-mass material with insulation on one side such that the thermal-mass material can have reasonable simulation Simulation effects.

FLOATING WALLS
There are modelling situations where we need additional walls to the walls Walls to those created automatically on Zone creation & that bound the edges of a zoneZone. In Hero we call these Special or Floating Walls Walls, in that they are not tied to the Edge of the Zone. Floating Walls can generally have the same attributes as normal wallsWalls, they can have windows Windows on them, and be attached to screensScreens, eaves Saves & wingWing-walls etc.
To Draw A Floating Wall use the Draw Special Floating Wall Drawing Mode which is detailed in the Drawing Mode tutorial section.
Special Floating walls Walls can be used to model situations such as:
Horizontally split wallsSplit Walls, such as a wall that changes assemblyAssembly, insulation or external colour Insulation or External Colour etc half-way up the wall Wall or similar. In this situation we would create a new floating wall Floating Wall over the top of the wall Wall below, and set the Base Height of the Lower to 00mm, the Height of the Lower Wall to the height where the transition occurs above the level Level reference, and then set the height Total Height of the upper wall section. ** Show Example with Drawings & Hero **. Splitting a wall like we have just done is also required in the situation where there is a local shading object
Where there is a local Eave a portion of the way up a wall Wall and an unshaded section above. An eave Eave that has a negative vertical offset would be incorrect in this example situation as it means all the wall Wall above that vertical offset will be shaded in the model, whereas in this situation there is a portion that is unshaded that we may want to model. A split wall with an eave Eave attached to the local portion lower portion, and the Upper Wall having no Eave would be the appropriate solution for this situation. ** SHOW EXAMPLE WITH DRAWINGS & HERO **We can also use Special Floating Walls to model Clerestory walls
Clerestory Walls that lie above the ceiling Ceiling of the zoneZone. In this situation the base height Base Height of the wall Wall may need to be increased to the ceiling height Ceiling Height where the clerestory Clerestory begins. Eaves & windows Windows can be added to this Floating Clerestory as per normal walls. ** Show Example with Drawings & Hero **Walls.
Walls that are adjacent to Special Zones such as Roofspace Zones or Subfloor Zones. Floating walls Walls can be used in this instance with the adjacency type changed to Roofspace or Subfloor type in the Data-Grid Wall Adjacency column. ** Show Example with Drawings & Hero **
Walls or wallWall-like objects completely within the zone Zone that provide sufficient thermal mass Thermal Mass that you would like to model their effects. We call these Internal Thermal Mass walls within Hero, and they can be modelled using a Floating Special Wall & the Thermal Mass wall adjacency Adjacency option in the data-grid. For example in this projectthe Data-grid.

EXTERNAL WALLS FOR ROOFSPACES & SUBFLOORS
Special Zones such as Roofspace Zones & Subfloor Zones also can have their own walls Walls that are automatically generated by Hero and appear in the Data-Grid. This is discussed in further detail in the Special Zone section of this tutorial series.

NULL WALLS - WALLS WITH NO ADJACENCY
...
The most common example of this situation is walls that are facing adjacent to the cavity of a stud-wall such as created between two internal walls. In this situation the heat transfer into the side of the stud cavity cannot be accounted for. Hero will attempt to auto-detect these situations & if detected, will remove the wall Wall segment in this location. However there
