BASIX & Thermal Comfort Certificates

At the BASIX Certificate Centre we can provide you with a NatHERS Certificate, or commonly called a Thermal Comfort Certificate (Thermal Performance) by an ABSA approved assessor, complete and ready for submission with your BASIX Certificate to council.  This is also referred to as the Simulation Method. (See how)

ABSA or Australian Building Sustainability Association represents building and design professionals who specialise in assessing the environmental impact of buildings. They use use sophisticated computer programs to analyse your building plans and can offer practical advice on cost-effective ways to improve its performance.

ABSA Assessors are specifically trained to ensure that your home meets the requirements of Council environmental regulation. This professional advice can save you time and money by eliminating any costly changes or delays caused by non-compliant plans. Accredited Assessors offer specialised skills. They’ve completed rigorous training and examination and are subject to regular auditing. They’re backed by Professional Indemnity Insurance and meet ABSA requirements for quality assurance and continuing professional development.

ABSA Accreditation is one of the few nationally recognised for Assessor training and Quality Assurance which meets the requirements of the NCC or Building Code of Australia, plus the NSW Building Sustainability Index ( BASIX ). In some states it is mandatory to use an Accredited Assessor to carry out Building Thermal Performance Assessments.

Plus, combined with our extensive knowledge of the Housing Industry we will provide you with suitable and practical solutions for your construction, meeting the current targets set by BASIX.

Our assessor will calculate the Thermal Comfort simulations based on minimal construction costs, or tailored to suit your specific needs or wants.
