As Built Energy Rating Verification

We ensure your home is being constructed in accordance with your official energy star rating.

DID YOU KNOW THAT THERE ARE NO INSPECTIONS TO ENSURE YOUR HOME’S ENERGY RATING?

The Nationwide House Energy Rating Scheme (NatHERS) measures a home’s energy efficiency. Currently, your home has to achieve a minimum of a 6-star rating. However, this evaluation is purely theoretical.

Currently, there is no requirement to inspect new homes are being constructed in accordance with the home’s energy rating report.

That leaves homeowners completely vulnerable, having to trust their builder and tradespeople to install all elements of the home in accordance with the home’s approved design plans. It is not uncommon that people pay for a 6-star home and end up getting a house that only performs to a 4-star level. This is not only a breach of trust but will ultimately end up costing you way more in heating and cooling (not to mention the health and environmental impact). 

WE ARE PUTTING YOU BACK IN CHARGE

Our service provides assurances to the homeowners that their home will perform as intended in the energy rating report – and they are getting what they paid for.

HOW IT WORKS

We review your home’s construction plans, your energy rating report, and your window supplier’s specification. We also correspond with your builder to schedule onsite inspections to check that the underslab, slab edge, and/or subfloor insulation as well as the wall, ceiling, and roof insulation is installed correctly and the R-values are in accordance with the energy rating report.

We also inspect all the windows and make sure the right models have been used and they have been installed and sealed correctly.

In addition to that, we also conduct a post plaster airtightness test with our blower door system as well as a thermal camera inspection to ensure the insulation is installed in accordance with the energy rating report.

BLOWER DOOR TEST

An initial inspection is carried out onsight to ensure everything is safe to operate the blower door. 

We then install our Retrotec 5100 Blower Door System in an external door and depressurise your home to a pressure difference of 50 pascals. The blower door system will then tell us what the air changes per hour are and allow us to quickly identify the spots in your home that cause the biggest air leaks. 

Outlier Thermal Imaging

THERMAL IMAGING

In addition to the blower door test, we also inspect the entire home internally using our Flir E8 Infrared camera to document air leakage, insulation, and thermal bridging defects.

The thermal imaging allows us to see where thermal bridging is occurring, and identify missing insulation in the walls, floors, and ceiling.

Email updates of each stage will be issued to the client identifying any non compliance or defects, including photo documentation. We then issue a final report upon completion of the home’s construction. 

FREQUENTLY ASKED QUESTIONS

What happens if you find inconsistencies during your inspection?

We will send you an email after the inspection outlining the results including any defects or variations to the energy rating report. Apart from all the necessary details, reports, and documentation, we also provide guidance for you to talk to your builder about rectifying the issues we found.

What is the time frame from start to finish?

The duration of the home build. We issue a detailed review and give an update including photos and documentation after each inspection. 

Where do you offer your service?

We offer our services within a 300km radius of Bendigo, VIC, with an hourly rate of $135 +GST for travel over 1 hour from Bendigo.

Can I be present during the blower door test?

You do not have to leave the house – we have even tested existing homes while the owners are at home working on the computer – and it hasn’t been a problem with loose items such as paper. However, we ask that all external doors and windows remain closed and all internal doors remain open whilst we are depressurising the home with the blower door system. For this to be achieved, it is best if we can prevent people from entering and exiting the home while we are testing.
