Domestic Practices and User Experiences Pre- and Post- Occupancy in a Low-Carbon Development

Examination of how household practices, resource flows and social contexts change after moving into an innovative development in Western Australia, with a focus on the home system of practice. This research demonstrates that while some aspects of domestic practices may change when the context changes, entrenched habits and personal practice history prescribe how practices are performed and the subsequent resources consumed

Food Waste and Social Practices in Australian Households

Food waste is a critical sustainability issue, and the solutions, particularly in middle- to high-income countries, lie in shifting practices within households. The purpose of this paper is to contribute to the research in an Australian context, provide insights from a social practice theory approach and understand the influence of growing your own food to waste production. The research is based on respondents completing a two-week food diary documenting food acquisition and disposal and then undertaking a survey on their food practices and attitudes to waste. This study finds that the preparation of meals and storage practices are critical towards the production of food waste. These practices can be shifted by focusing on upskilling and the introduction of new materiality or technologies. The acquisition of food is also a pivotal practice in which to intervene in order to reduce waste in other food practices in the household. Interventions, such as growing your own food, are recommended to shift food practices to reduce an output of waste to landfill. The research is limited by its reliance on self-reported data for food waste. However, the focus on social practices in food waste is novel in an Australian context

Pre- and Post-Occupancy Evaluation of Resident Motivations for and Experiences of Establishing a Home in a Low-Carbon Development

There is some understanding of how an individual’s daily practices consume resources in the home, but the home as a space itself and peoples’ relationships to it remain an interesting research area. In this paper, residents of an Australian low-carbon development (LCD) are studied in order to discover the expectations and motivations driving them to move to their new home, the emotional landscape of the home, and their subsequent experiences living in an LCD. This exploration through mixed methods and a post-occupancy evaluation enables a longitudinal empirical study of the motivations, perceptions, expectations and experiences of an LCD residence. This study aims to further conceptualize the social understanding of a home and what people consider when moving into an LCD, along with the post-occupancy experiences that are important for establishing LCDs in the future. The results show that a home is associated with being a place of community, sustainability, safety and comfort, as well as a place that incorporates aesthetically pleasing features. The motivation for residents moving into an LCD is to have housing stability, live the life they want (including performing sustainable practices) and enjoy the attractive design of the LCD. The user experiences of living in an LCD include unexpected design influences on daily practices and an appreciation of the community atmosphere created. The strong sense of community and the self-reported thermally comfortable homes met residents’ expectations post-occupancy. This research is of interest to academics in the low-carbon and social science sectors, real-estate agents and property developers, as it provides insight into motivations and expectations of low-carbon dwelling residents

The Discrepancy between As-Built and As-Designed in Energy Efficient Buildings: A Rapid Review

Energy efficient buildings are viewed as one of the solutions to reduce carbon emissions from the built environment. However, studies worldwide indicate that there is a significant gap between building energy targets (as-designed) and the actual measured building energy consumption (as-built). Several underlying causes for the energy performance gap have been identified at all stages of the building life cycle. Focus is generally on the post-occupancy stage of the building life cycle. However, issues relating to the construction and commissioning stages of the building are a major concern, though not usually researched. There is uncertainty on how to address the as-designed versus as-built gap. The objective of this review article is to identify causes for the energy performance gap in buildings in relation to the post-design and pre-occupancy stages and review proposed solutions. The methodology applied in this research is the rapid review, which is a variant of the systematic literature review method. Findings suggest that causes for discrepancies between as-designed and as-built energy performance during the construction and commissioning stages relate to a lack of knowledge and skills, lack of communication between stakeholders and a lack of accountability for building performance post-occupancy. Recommendations to close this gap during this period include better training, improved communication standards, collaboration, energy evaluations based on post-occupancy performance, transparency of building performance, improved testing and verification and reviewed building standards

East Village at Knutsford: A Case Study in Sustainable Urbanism

With increasing pressure to ensure that sustainability features in homes are commercially viable, demonstration projects are vital to highlight the real-world challenges and opportunities for innovation. This paper documents the incorporation of sustainability objectives into the “East Village at Knutsford” residential “living laboratory” development, within the Knutsford urban regeneration precinct, approximately 1.5 km east of the Fremantle central business district in Western Australia. The sustainability objectives for the project include being a “Net Zero Energy Development” using 100% renewable energy and maximizing the self-supply of energy, reducing mains water consumption as much as is practical, and using the landscape design to complement these objectives without compromising a best-practice urban greening outcome. The paper documents the design initiatives and strategies that have been included to achieve these objectives in a commercially viable project and the results of modelling where it has been used to test the design against the objectives to ensure their validity. The key features that have been incorporated into the townhouses component of the development are outlined, illustrating integrated design and systems thinking that builds on previous demonstration projects, incorporating solar energy storage and electric vehicle charging plus significant mains water savings by adopting water-sensitive features in the homes and the within the private and public gardens. The expected grid energy and mains water consumption levels in the homes through modelling compared to the metropolitan average is 80% lower. The project is presented as an important step in the application of available technologies and design features to meet stated sustainability objectives, highlighting the benefits of an embedded living laboratory research approach

Understanding resource consumption in the home, community and society through behaviour and social practice theories

The practices and behaviours of individuals influences resource consumption at many scales and are shaped by a multitude of psychological, social, and technical factors. This conceptual paper examines the differences between socio-psychological and social practice theories, building on the Chalk and Cheese debate in the literature. Insight is provided into their potential value in understanding resource consumption studies at different scales: the individual, the home, community, and societal. Each theory has its own qualitative and quantitative methods which allude to different conclusions and recommendations for resource consumption initiatives. We review the debate surrounding the application of both theories, adding our voice to the potential for both theories to be used at different scales and for different time periods, along with comments on the interlocking nature of practices. Design and technology changes can lead to quicker changes in behaviour and practices, whereby socio-psychological theories offer insights into changes in mind frame, values, and social norms

Ecological urban planning and design: A systematic literature review

Urbanization is a defining feature of the modern age, yet the current model of urban development profoundly alters the natural environment, often reducing biodiversity and ultimately threatening human wellbeing. An ecologically based urban planning and design paradigm should consider a more harmonious relationship. Through a systematic literature review of 57 papers, this research identified relevant concepts and theories that could underpin this new paradigm. It revealed a noticeable increase in academic interest in this subject since 2013 and the development of concepts and theories that reflect a more holistic socio-ecological systems approach to urban planning and design based on a transdisciplinary integration and synthesis of research. Seven main themes underpin the academic literature: ecosystem services, socio-ecological systems, resilience, biodiversity, landscape, green infrastructure, as well as integrated and holistic approaches. Six of these can be organised into either a sustainability stream or a spatial stream, representing the foundations of a potential new ecological urban planning and design paradigm that applies sustainability-related concepts in a spatial setting. The final theme, integrated and holistic, includes concepts that reflect the fundamental characteristics of this new paradigm, which can be termed 'urban consonance'
