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.

Info

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

Site Exposure

An attribute that describes the site context of each Individual Dwelling & that effects simulated wind & ventilation-speeds within the Chenath Simulation via a Shielding Factor.

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 (Shielding Factor 0.88)

  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 (Shielding Factor 0.74)

  3. Suburban: Numerous closely spaced obstructions less than or equal to 10 m. E.g. Suburban housing, heavily vegetated bushland areas, townhouses (Shielding Factor 0.57)

  4. Protected: Numerous closely spaced obstructions greater than 10 m. E.g. City and industrial areas (Shielding Factor 0.31)

Note

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.

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.

Tip

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.
