About the rating

NatHERS software models the expected


thermal energy loads using information
about the design and construction, climate
and common patterns of household use.
The software does not take into account
appliances, apart from the airflow impacts
from ceiling fans.

Verification
To verify this
certificate, scan the
QR code or visit
hstar.com.au/QR/Generate?

When using either link, ensure you are

National Construction Code (NCC) requirements


The NCC’s requirements for NatHERS-rated houses are detailed in 3.12.0(a)(i) and 3.12.5 of the NCC Volume Two. For apartments the requirements are
detailed in J0.2 and J5 to J8 of the NCC Volume One.
In NCC 2019, these requirements include minimum star ratings and separate heating and cooling load limits that need to be met by buildings and
apartments through the NatHERS assessment. Requirements additional to the NatHERS assessment that must also be satisfied include, but are not
limited to: insulation installation methods, thermal breaks, building sealing, water heating and pumping, and artificial lighting requirements. The NCC and
NatHERS Heating and Cooling Load Limits (Australian Building Codes Board Standard) are available at www.abcb.gov.au.
State and territory variations and additions to the NCC may also apply.

0006038525 NatHERS Certificate 6.2 Star Rating as of 24 May 2021

Certificate check
Ensure the dwelling is designed and then built as per the NatHERS Certificate. While you need to check the accuracy of the
whole Certificate, the following spot check covers some important items impacting the dwelling’s rating.

Genuine certificate
Does this Certificate match the one available at the web address or QR code in the verification box on the front page? Does the
set of NatHERS-stamped plans for the dwelling have a Certificate number on the stamp that matches this Certificate?

Ceiling penetrations*
Does the ‘number’ and ‘type’ of ceiling penetrations (e.g. downlights, exhaust fans, etc) shown on the stamped plans or installed,
match what is shown in this Certificate?

Windows
Does the installed window meet the substitution tolerances (SHGC and U-value) and window type, of the window shown on this
Certificate?

Apartment entrance doors


Does the ‘External Door Schedule’ show apartment entrance doors? Please note that an “external door” between the modelled
dwelling and a shared space, such as an enclosed corridor or foyer, should not be included in the assessment (because it
overstates the possible ventilation) and would invalidate the Certificate.

Exposure*
Has the appropriate exposure level (terrain) been applied? For example, it is unlikely that a ground-floor apartment is “exposed”
or a top floor high-rise apartment is “protected”.

Provisional* values
Have provisional values been used in the assessment and, if so, noted in “additional notes” below?

Additional notes
Job# 43392
Downlights between levels do not penetrate insulation and have no impact on this assessment.
