BASIX® & NatHERS (UPDATE!)
Its been 3 months since 7 Stars was implemented in NSW along with the new BASIX system and you all know I have wanted to scream more than 3 times! (maybe 3 times per project?) 😬
A massive THANK YOU to those clients that have stuck with me while I sort through updating certificates and generating new certificates...🥰
So what are the issues? It is no longer enough to just reach the BASIX cooling and heating loads, the overall loads must also reach 7 Stars.🏠
NatHERS
General Design
It can take a while for projects to get off the ground and so its a bit in the middle of "finishing off" projects and starting projects at the moment and this is totally understandable, however the implementation of 7 Stars was not an unknown so please, do give your clients a heads up.
New projects need to be designed FOR THE SITE. 🏖🏜🌋Not from a template! (and trust me, I am a massive fan of templates!) but this is not going to "cut the mustard".
Go back to basics:
Where is North? This is where the living / kitchen goes!
How big are my room sizes and what is the glass to floor ratio?
What voids do I have?
What are my construction materials?
New standards
ALL projects will be applied with the following (if not already specified):
COSG+R2.0+1.8 Slab edge (This performs better than waffle pod)
R4 between levels (or underfloor if a suspended slab)
R6 to Ceiling
R2.0 to internal walls, R2.5 to the internal garage wall
1200 ceiling fans to Living rooms and 900 ceiling fans to bedrooms and studies.
Upgrading from here I can apply windows with a max of:
PVC-006-03 W uPVC B DG Argon Fill High Solar Gain low-E -Clear
PVC-005-03 W uPVC A DG Argon Fill High Solar Gain low-E -Clear
After this, I need to start applying design changes. So far I have been finding:
Changing roof colour (sometimes)
Cladding at ground floor to either Brick Veneer or XPS
Changing floor coverings (to polished concrete, don't get excited for a saving on this one!) AND the last one which is very much my least favourite:
Changing your design...
Frequently asked Questions🧐
I am building up a sheet of FAQ's - please let me know if you want me to add any to have at your disposal! So far the most common are:
Can you take out the double glazing / thermally broken etc, I only want/can afford the single glazed.
I apply all other "upgrades" I can BEFORE windows. Windows are the last used to reach the required target as they are the most "expensive" of a build. Please qualify your clients budget BEFORE you start! If you walk into a supermarket with $3 and the fancy loaf of bread is $3.50 what do you do? ... this is no different! (if you know me well enough, you will also know this is how I feel about 4.6 variations and variations to DCPs!)
My window supplier doesn't have those windows
Yeah, nah...This is not a "me" problem, this is a "supplier" problem and there is no such thing. The windows used within the NatHERS system have been there / available since before I started doing assessments (more than 5 years ago! *gulp*). Your supplier needs to have values the same as or better, or you can find the exact windows you will be using in construction using the WERS website (and if these windows don't pass - you got it, we go back to changing the construction method...). The suppliers DO know this... this is literally their J.O.B!
I do have a handy video and fact sheet that I can send you if you need, please ask!

Updating old Certificates
In order to update a Certificate you need to have the PAN number handy. If the lodgement date was not within 3 months of the certificate, it will reject it which becomes a problem if you haven't lodged it! This didn't happen in the old system as it was not linked to a particular development / site. I have asked for it to be fixed, they do not see it as a problem or actual issue and cannot see the logic... You will need to pay for the new certificate (and a lovely portal fee for the convenience too, oh and transaction fee! both of which they also didn't have...)
Generating new Certificates
If you have a contract signed pre 1 October, it can be assessed against the pre 7 Star target (and lordy, please let me know this at the start!).
Otherwise the new certificate is assessed against the new targets and has LOTS more details... It is taking an average of 3 times longer for me to do a certificate with the additional information required (and see above - 5 years and going people, my typing speed is faster than Lighting McQueen! Zoom, Zoom!). 🏎
Most of the additional information is available from your plans or the NatHERS assessment, some is also still not clear which is where the additional questions will come from. Thanks for your patience... in advance!
The Department are keeping us informed through our Accrediting Office, its slow going...
I am more than happy to chat through the above, Your business IS my business!
