At present, building scale energy efficiency is often limited to the design stage; therefore, the post occupancy energy efficiency of dwellings rarely gets reported. Australian households receive quarterly energy bills; however, these bills, which show aggregated energy consumption, are not helpful in understanding the breakdown of energy usage that would inform changes to the energy consumption behaviour or develop strategies for energy savings.This pilot project was designed to address this gap in energy usage information through development of an integrated visualisation platform to allow households to explore their indoor comfort conditions, and disaggregate electricity consumption and water consumption at residential scale.
In response to feedback, high-income households can reduce their energy use to a larger degree than low-income households (17% vs 3% reduction). This and other insights were gained by two rapid reviews into research, both Australian and International, on digital services and...Read more
Industry misconceptions around high cost and poor market interest in energy efficient homes continue to obstruct the mass adoption of low carbon housing. Josh’s House demonstrates that low carbon housing is accessible and cost effective. The Star Performers series showcases how...Read more
When South Eastern Australia was in severe drought at the beginning of the century, a whole array of efforts went into addressing the water shortage. Councils introduced, and then increased, water restrictions. Government handed out low-flow showerheads and shower timers,...Read more
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.
The Building Sustainability Index (BASIX) assessment tool estimates the operational energy consumption and GHG emissions from new residential developments based on information available at the building design stage. However, post-occupancy energy consumption can be different from the estimated figures at the design stage.
Evaporative Cooling (EC) is increasingly regarded as a powerful and effective method for building cooling, mitigation of Urban Heat Islands (UHI) and for urban adaptation to climate change (Kitano et al., 2011; Saneinejad et al., 2014).
This guide offers practical advice to homeowners, builders and designers embarking on a retrofit of an existing home. It focuses on relatively simple adaptations to improve a home’s comfort, while reducing energy bills and carbon emissions.
