Capability Statement

BASIX Certificates

Certificates for Residential Developments in NSW

Our BASIX Consultants are highly experienced in tackling even the most challenging designs and large multi unit residential projects. We use NatHERS thermal modeling in preparation of every BASIX Certificate even for the smallest single dwelling projects.

BASIX or Building Sustainability Index is a government mandatory sustainability initiative for NSW residential developments that needs to be provided as part of a Development Application. BASIX overrides the Volume 2 requirements of the National Construction Code (NCC) and provides a more robust and informed evaluation of the building. To learn more please visit our

NCC / BCA Section J Report

Reports for Commercial Developments

Having completed hundreds of NCC / BCA Section J Compliance Reports both by Deemed to Satisfy (DTS) solution as well as  JV3 alternative solutions, our team at Eco Certificates guarantees council approval for compliance with energy efficiency requirements of the section J of the National Construction Code, Building Code of Australia Volume 1.
National Construction Code / Building Code of Australia Section J, Energy Efficiency, provides energy efficiency compliance requirements for NCC standard building classes 2 to 9. A NCC / BCA Section J Report must be compiled for every non residential development across Australia to demonstrate that the proposed development complies with the requirements of Section J of the National Construction Code. To learn more please visit our NCC / BCA Section J Report page.

NatHERS Assessment

NatHERS Thermal Comfort Assessment for Residential Developments

By using the latest version of HERO and BERS Pro second generation NatHERS thermal comfort assessment software packages, our assessors can model and simulate the thermal comfort performance of even the most complicated and challenging residential building designs. We have thousands of different dwellings in our resume and there is simply no design complexity which we have not seen yet.

National House Energy Rating Scheme or NatHERS is the national government regulatory framework that governs the thermal simulation of residential developments addressed in the National Construction Code. To perform a NatHERS thermal assessment an Accredited Assessor must simulate the building with a NatHERS thermal simulation software package. To learn more please visit our NatHERS page
