Validating and Improving the BASIX Energy Assessment Tool for Low-Carbon Dwellings: Final Report

This report is a product of the collaborative research project ‘Validating and Improving the BASIX Assessment Tool for Low-Carbon Dwellings’. Initiated by the Cooperative Research Centre for Low Carbon Living, the University of New South Wales (UNSW) and the New South Wales Government, this project addresses the policy need for post-occupancy evaluation of the BASIX tool by measuring the actual energy consumption of BASIX-compliant dwellings. This report outlines the key findings of this project by highlighting the discrepancies between BASIX estimations and measured energy consumption and provides an in-depth analysis as to why there are discrepancies and what causes them. Project outcomes fill the gap towards achieving a systematic understanding of actual energy performance of BASIXcomplaint dwellings, including the complex and interrelated attributes that contribute to these discrepancies.
