NatHERS Assessment for new homes

At Arrow Energy Ratings we provide fast turnarounds on all NatHERs approved assessments.

Assessments are carried out using the most up to date version of First Rate 5 Assessment software as approved by the software administrator.

Using the guidance of Technical Note 1, Ver 1.2 and our wealth of experience in assessing new residential projects, you can be confident in the outcomes proposed.

All finalised assessments are produced including a full Energy Specification, NatHERs Universal Certificate, Diagnostics and your drawings are endorsed for your building surveyor's satisfaction.

Residential Deemed to Satisfy

Do you have a small extension which measures less than 25% of the overall dwelling floor area? Or are you building a small studio or workspace?

Let us take care of the Deemed to Satisfy provisions to ensure you have all of the documentation necessary to satisfy your building surveyor.

You will be presented with a comprehensive Deemed to Satisfy report ensuring new works meet the Building Code requirements, appropriate glazing calculators with new glazing recommendations and endorsed drawings.

Comprehensive Residential HERs for Alterations and Additions

Have a new extension project measuring over 25% of total floor area? Then a House Energy Rating Assessment may be required.

Let us prepare all of the necessary documentation for you.

As HERs specialists we can quickly and effortlessly produce all of the necessary documentation required to satisfy residential building surveyors that the energy requirements of the BCA and Practice Note 55 are met.

With the production of a comprehensive report, diagnostics, recommendations and endorsement you can rest assured that your new extension will meet the thermal performance provisions of the Building Code.

Section J Commercial Assessment

Building or renovating for commercial purposes? We've got that covered too!

We have the knowledge and experience to prepare Section J thermal performance assessments meeting the many criteria to satisfy your building surveyor. Preparation of comprehensive reporting, glazing calculators and endorsed documentation to meet the Building Code requirements.

Windows and Glazing

We recognise that windows and glazing are one of the most contentious aspects of any energy assessment. Ensuring you have the correct windows listed on the energy assessment without blowing the build cost budget is essential!

We work closely with our clients, window manufacturers and the end user to ensure that the glazing requirements are listed correctly in all energy assessments.
