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?
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.
