Zone Type | Description |
|---|
Kitchen/Living | | Expand |
|---|
| title | As per NatHERS Technical Notes: |
|---|
| “Any room shown on a plan as a kitchen or a kitchen combined with one or more living areas. This zone must include the main kitchen area and may include a lounge, meals or dining area.
All dwellings must contain one main kitchen/living zone. There can be no more than one kitchen/living zone. All additional smaller kitchens/kitchenettes within the dwelling must be zoned as another zone type.” |
Examples: Kitchen, Kitchen/Living, Kitchen/Dining |
|---|
Living | | Expand |
|---|
| title | As per NatHERS Technical Notes |
|---|
| “This is the default zoning for internal zones not covered by any other zone type.
Daytime zones include studies (without a built-in wardrobe), gymnasiums, internal domestic lifts, indoor pool rooms, saunas, above ground wine cellars, walk-in pantries, storage areas or conditioned outdoor living areas capable of being fully enclosed (i.e. considered within the dwelling envelope).
This zone type includes hallways and corridors (either fully enclosed by doors or open to other zones) as they are circulation areas that allow access to other zones. This includes zones such as ensuites or walk-in wardrobes that can be accessed by a hallway or corridor (e.g. a two-way bathroom accessible by both a bedroom and the hallway).
This zone type could also include any living, lounge, dining, family, rumpus, media or home theatre room, if they are in addition to the two largest living areas.
This zone may be selected when a laundry, WC, bathroom or powder room is not ventilated by a door or window on an external wall.” |
Examples: Living, Lounge, Dining, Family, Rumpus, Media, Theatre |
|---|
Bedroom | | Expand |
|---|
| title | As per NatHERS Technical Notes |
|---|
| “Any room shown on the plan as a bedroom, whether or not it has any built-in wardrobes.
Bedroom zoning must also be used for a study with either a built-in wardrobe, walk-in wardrobe or attached ensuite. In this case, the ‘study’ becomes a bedroom zone with the built-in wardrobe part of the same zone. A walk-in wardrobe or ensuite is to be zoned as night-time.” |
Examples: Bedroom or Study with Wardrobe |
|---|
Day Time | | Expand |

Examples: Laundry or WC or Bathroom with No External Window/Door, Study, Hall, Corridor, Store, Pantry |

Night Time | | Expand |
|---|
| title | As per NatHERS Technical Notes |
|---|
| “This applies to areas that can only be accessed from a bedroom or from a zone, which itself, is only accessed from a bedroom. These include ensuites, walk-in wardrobes, parent’s retreats and WCs accessed from an ensuite.)” |
Examples: Ensuite, WIR accessed from Bedroom |
|---|
Unconditioned | | Expand |
|---|
| title | As per NatHERS Technical Notes |
|---|
| “Every dwelling must have at least one unconditioned zone.
Laundries, bathrooms, airlocks, WCs or powder rooms that have an external wall with at least one or more ventilation openings (window or door).
If there are no rooms that fit this description, then the smallest daytime zone must be modelled as an unconditioned zone.
An airlock is a small, relatively airtight space that can be modelled as unconditioned space if:
- it is located at a dwelling entrance and
- has one or more external walls and
- has one or more internal walls and
- has an external door and
- has one or more internal doors, of which, only one opens to a conditioned zone.
Where an area labelled as an ‘airlock’ does not meet the above conditions, it is to be modelled as a daytime zone.
Underground cellars may also be considered an unconditioned zone.” |
Examples: Laundry or Bathroom or WC or Powder, with External Window/Door |
|---|
Unconditioned Garage | | Expand |
|---|
| title | As per NatHERS Technical Notes |
|---|
| “Where a garage is shown on the documentation as attached to the dwelling, and does not have any heating or cooling indicated.” |
Examples: Unconditioned Garage |
|---|
Conditioned Garage | | Expand |
|---|
| title | As per NatHERS Technical Notes |
|---|
| “This zone type only applies when a garage has heating ducts, hydronic heating elements or air conditioners.” |
Examples: Garage with Heating and/or Cooling |
|---|
Corridor (Class 2) | | Note |
|---|
Hero models all Class 2 Corridors (whether they are Unglazed or Glazed as per NatHERS Definitions) as a single “Corridor” Zone Type to minimise user confusion & simplify Model creation. |
Hero decides automatically (based on whether the Corridor Zone has Glazing) as to whether to Simulate the Zone within Chenath as a Special Chenath “Glazed Corridor” Zone, or as Neighbouring Adjacency |
|---|
Carpark (Class 2) | | Expand |
|---|
| title | As per NatHERS Technical Notes |
|---|
| “Where there is a shared carpark underneath an apartment, and the carpark is equal to or greater than 50 per cent closed from the outdoor air, then the area directly under the apartment must be zoned as ‘shared basement carpark’. Where a carpark under the apartment is greater than 50 per cent open to the outdoor air then this zone must be modelled as ‘above outdoor air’.
This zone type must only be used in Class 2 and 4 dwellings. (More information available in Table 3).
This zone type must not be used when Class 2 dwellings have individual garages.” |
Examples: Basement, shared carpark (Class 2 or 4 only) |
|---|
Void | The Void Zone Type is used to model a special situation where a Zone resides over Multiple Levels. The Void Zone should be the Upper Zone. Modelling a Zone as a Void means that all of it’s child objects such as Walls, Ceilings & Openings are modelled as a Single Zone within Chenath. | Tip |
|---|
Note a Void Zone does not need a Hole across the entirety of it’s Floor, this is assumed automatically by Hero (though you can if you’d like, though it will have identical effects). |
