The Project Type determines the type of NatHERS Certificate issued for the Project and is a critical property of the Project

The available Project Types include:

• Class 1a New House/Townhouse(s):
  Default Project Type within Hero for a completely new House(s).
  Note can be used for Multi-Dwelling Class 1a Projects so that many townhouses or homes on a single development can be modelled within the one Project & Hero file.

• Class 1a Alteration/Extension House/Townhouse - Existing/Pre-Renovated Rating:
  Represents a Existing or “Prior to Renovation” NatHERS Assessment Project.
  For Renovation Projects, this Existing NatHERS Assessment & Hero File may be used to determine the Proposed Project’s required Star-Rating as per Building Regulation guidance

• Class 1a Alteration/Extension House/Townhouse - Proposed/Renovated Rating
  Represents the Proposed NatHERS Assessment for a Renovation Project. May be used in combination with an Existing House NatHERS Assessment if required for partial compliance.

• Class 2 Apartment(s)
  Class 2 Projects typically have different star-rating requirements than Class 1a Project.
  A Class 2 Project is also issued a NatHERS Summary Certificate within the Hero Web-Portal that documents the Average Star-Rating for the Project as well as the individual Dwelling Star-Ratings.

• Class 4 Dwelling(s) Above Another Class Building

Project Data-Grid

The Project’s Street Address that will be added to the NatHERS Certificate

Project Data-Grid

The Project’s Post-Code.

Used within the NatHERS Certificate and also to determine the NatHERS Climate Zone that can be used for the Project

Project Data-Grid

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.

Project Data-Grid (Dwelling Data-Grid for Multi-Dwelling Projects)

An area available for the User to Document any additional information to be added to the NatHERS Certificate as per NatHERS & AAO Requirements.

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.

Project Data-Grid (+ Dwelling Data-Grid for Multi-Dwelling Projects)

An area available for Users to record their own information relating to the Project for their own purposes such as for QA or organisational purposes.

Project Data-Grid

The available NatHERS Climate Zones for the Project as determined by the Post-Code.

All Post-Codes have a Main Climate Zone, and some have further Alternative Climate Zones that may be used.

When Alternative Climate Zones are used, as per NatHERS Technical Note guidance, this should be documented in the Certificate Notes section of the Project Data-Grid.

The Climate Zone determines the Weather File that will be used for Chenath Simulations.

Project Data-Grid

An attribute that describes the site context of the Project & that effects simulated wind-speeds within the Simulation.

These are defined & guidance given to their selection within the NatHERS Technical Notes

Options include:

1. 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

2. 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

3. Suburban: Numerous closely spaced obstructions less than or equal to 10 m. E.g. Suburban housing, heavily vegetated bushland areas, townhouses

4. Protected: Numerous closely spaced obstructions greater than 10 m. E.g. City and industrial areas

The Direction of North on the Plans as relating to the way the Project is modelled in the Visual View.

Effects all Model objects within the Project and accounts for the fact that some Plans similarly have a Project North arrow in a direction other than directly up the page
