Buildings are major consumers of energy for heating and cooling. The number of buildings is growing rapidly with demand for energy. To reduce consumption, governments worldwide have implemented codes, standards, and building practices.

Energy consumption in the building sector is significant as people are spending a considerable amount of time indoors. The share of the residential sector’s energy consumption is around 11% of the total energy consumed in Australia to fulfil household energy requirements. The largest share of that energy consumption is used to maintain indoor thermal comfort.

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.
