Estimation of the demand of an urban precinct, related to Electricity, Transport, Waste and Water (ETWW), is a necessary step toward the delivery of quality living environments where daily activities can be conducted in a sustainable manner. A forecasting model that concurrently links demand in all four aforementioned domains to carbon emissions can assist planning agencies, infrastructure providers, operators and private developers to deliver low-carbon urban precincts in the future. Integration of modelling methodologies delivers improved ability, accuracy and flexibility when compared to typical forecasting approaches.
This chapter details the outcomes of recent research efforts on the development of an integrated ETWW demand estimation tool with detailed scenario forecasting abilities. Focusing on the residential components of the precinct, modelling outputs provide detailed estimations of household demands and resulting carbon impacts across the four domains. Impacts of non-residential land uses including high-value industry, retail, commercial and open space are also considered and reported on. Model users can estimate the carbon impact of resident population changes, various household structure types, carbon-friendly technologies and climate change for precinct locations across Australia. In addition, the tool accounts for interactions with external infrastructure such as transport networks, off-site waste disposal, water supply locations and grid-based energy supply. Forecasting abilities of the model are demonstrated through case-study applications that reflect of ‘what-if’ type scenario investigations, important to policymaking and planning for future urban development. The user is ultimately able to explore combinations to achieve a low-carbon precinct development.
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
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
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
Demand estimation for services and facilities is an important component of urban development, being required for the determination of the level of provision and coverage of infrastructure and related facilities to serve the needs of present and future populations. Demands and associated cabin impacts for the domains of energy, transport, waste and water (ETWW) are significant to planning agencies, infrastructure providers and operators and private developers who all need to deliver services and resources to urban precincts.
While the focus is on the City of Belgrade, the aim of this report is to support all public authorities and agencies developing and implementing integrated approaches to both energy efficiency in buildings and district energy supply. It provides guidance to decision-makers in Belgrade, while presenting universal recommendations to align district energy and energy efficiency in buildings. Combining energy efficiency measures and district energy is often seen in the context of achieving deep decarbonisation in the most cost-effective manner.
