Dwellings

OVERVIEW

A Dwelling within Hero represents a single Home or Apartment within the Project..

Hero is a multi-dwelling modelling tool in that it allows all dwellings to be modelled within the one Hero Project & save file.

Dwellings have separate Chenath simulations performed upon them, and are issued individual NatHERS Certificates with the project having a NatHERS Summary Certificate issued that agglomerates individual Dwelling NatHERS Star-ratings.

Hero also creates a special dwelling called a Common Area Dwelling for Class 2 multi-dwelling projects to contain Common Area Zones such as Carparks & Corridors (see below).

DWELLING PROPERTIES

PROPERTY	DESCRIPTION	EDITED WITHIN
Name	The Name of the Dwelling	Dwelling Data-Grid
Unit Number Address	The Unit Number or sub-address of the Dwelling that will be prepended to the Project’s Address for NatHERS Certificates. E.g. A Dwelling with Unit Number “Unit 24” and Project Address “100 Main St” will have a final address on the NatHERS Certificate of “Unit 24, 100 Main St”	Dwelling Data-Grid
Lot / Deposited Plan (DP) Number	Lot or Deposited Plan Number for the Project as per the existing or future Title. Used so that NatHERS Assessments can be tied to specific addresses regardless of future changes to addresses etc, and will potentially make it easier for future search & retrieval of NatHERS Assessment information by future owners or occupants. For Multi-Dwelling Projects, the Lot Number is entered on a Dwelling by Dwelling basis and can be found & edited within the Dwelling Data-Grid	Project Data-Grid (Dwelling Data-Grid for Multi-Dwelling Projects)
Site Exposure	An attribute that describes the site context of each Individual Dwelling & that effects simulated wind-speeds within the Simulation. These are defined & guidance given to their selection within the NatHERS Technical Notes Options include: Exposed: Few or no obstructions. E.g. Flat grazing land, lake-side, ocean-frontage, desert, exposed high-rise unit without obstructions at a similar height to the dwelling Open: Grasslands with few well scattered obstructions less than or equal to 10 m. E.g. Farmland with scattered sheds, lightly vegetated bush blocks, elevated units with a few obstructions of similar height to the dwelling Suburban: Numerous closely spaced obstructions less than or equal to 10 m. E.g. Suburban housing, heavily vegetated bushland areas, townhouses Protected: Numerous closely spaced obstructions greater than 10 m. E.g. City and industrial areas Each Dwelling has it’s own Site Exposure that is determined based on it’s lowest Zone. The Site Exposure Property for Multi-Dwelling Projects gets moved from the Project Data-Grid tab to the Dwelling Data-Grid tab. E.g: The Top Level Apartments of a Class 2 Project may be Exposed whereas the Ground Level apartments may be Protected or Suburban etc.	Dwelling Data-Grid (Project Data-Grid for Single Dwelling Projects)
Certificate Notes	An area available for the User to Document any additional information to be added to the NatHERS Certificate as per NatHERS & AAO Requirements for the Specific Dwelling. Typical uses of this section is to document any assumptions made for the project, any substitutions or deviations away from standard NatHERS Technical Note guidance. Certificate Notes at a Dwelling Level are combined with the Project level Certificate Notes. This enables the Project Data-Grid’s Certificate Notes to be used as Global notes for all apartments & the individual Dwelling Certificate Notes to be used for individual note requirements.

DWELLINGS WITHIN THE VISUAL-VIEW

Dwellings can be created, deleted & selected within the Visual-View Top Toolbar. The selected dwelling in the Visual-View Top Toolbar’s Dwelling list will become the parent Dwelling of any new Zones created within the Visual View.

For further information see Visual View Top Toolbar

DWELLINGS WITHIN THE DATA-GRID

For a Single Dwelling Project, most Dwelling information is integrated into the Project aspects of the Project Data-Grid and the Dwelling Data-Grid tab becomes hidden.

When a Project becomes a Multi-Dwelling project, the Dwellings tab is shown in the Data-Grid and further details on the Dwellings can be entered here.

COMMON AREA DWELLING

ZONES

A Dwelling contains one or more Zones that represent the individual rooms or separately modelled spaces in the Dwelling. Dwellings act as the Parent of Zone.

For further information see: Zones

DWELLINGS & CHENATH SIMULATIONS

Due to the limitations of the NatHERS simulation protocol as well as the Chenath Engine, Dwellings are all simulated separately with individual simulations within Chenath.

Adjacencies to Neighbouring Dwellings are modelled as Neighbouring Adiabatic within Chenath and no heat transfer is assumed between these adjacencies.
