Sustainability assessment tools aim to promote high sustainability outcomes in residential buildings, ensuring less consumption of water, energy and less emission of greenhouse gases. However, existing literature often presents variations between the estimated outcomes from the assessment tools and actual outcomes after building occupation. Research suggests that actual energy consumption could be significantly influenced by resident behaviour in addition to the dwelling conditions and the energy efficiency of appliances.
This qualitative study explores the nature of resident behaviour in achieving thermal comfort and how these influence the actual energy performance of BASIX-affected dwellings in NSW. A preliminary evidence-based behaviour model is developed to support the behavioural analysis. The model positions the heating and cooling effects of the dwellings’ design, the behaviour of residents in space heating and cooling, hot water consumption, etc. as well as multiple influential attributes such as resident's perceptions, preferences, attitudes and knowledge towards energy efficiency in relationship to energy efficiency outcomes. The model not only identifies the key drivers that trigger energy consumption behaviour, but also investigates the potential inter-relationships among all the key influential attributes. The findings of this research will inform the BASIX assessment tool, sustainability policy, building designs and government educational programs on sustainability.
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
Rapid global urbanization and the increase of the Urban Heat Island (UHI) effect make urban cooling a necessity as well as an opportunity to increase the liveability and amenity of cities. This review is a scoping study of the relevant worldwide UHI mitigation/adaptation...Read more
A rapid review on green-rated office buildings, and their operational energy use, found that the conclusions of six studies ranged from the certified buildings performing worse, similarly or much better than the non-certified buildings in terms of energy usage intensity. Two...Read more
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.
This book focuses on the challenge that Australia faces in transitioning to renewable energy and regenerating its cities via a transformation of its built environment. It identifies innovative and effective pathways for decarbonising the built environment from applied research undertaken by the Co-Operative Research Centre for Low Carbon Living.
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.
Most energy efficiency programs target only one fuel, usually electricity or natural gas. While they achieve savings, they sometimes miss opportunities by failing to address other fuels. Dual-fuel programs, on the other hand, have the potential to save more energy, reduce program costs, and improve customer satisfaction.
