ItemAssessing the social life cycle impacts of circular economy(ELSEVIER SCI LTD, 2023-02-01)A transition to a circular economy (CE) affects different stakeholders – positively and negatively. Social aspects still receive little consideration in the context of CE, which is why the assessment and monitoring of the social impacts of CE still require further development and consideration in research. In this context, social circularity indicators and social life cycle assessment (S-LCA) are important tools that were examined in more detail in this study. This paper aimed to assess the current state of social circularity indicators in the literature, the implementation of S-LCA to assess CE concepts, and which additional indicators might be included in future S-LCA studies. Focus will be on the methodological approach of how to assess the social impacts of CE. A systematic literature review was conducted using Scopus Database, Google Scholar, and Web of Science. The search terms were derived from the aim of the study to identify the social impacts of CE in existing literature, to compile relevant social indicators in the context of CE, and to analyze the current role of S-LCA in the assessment of CE concepts. 97 papers were found. After excluding contributions that did not match the search criteria and adding new relevant contributions found through the analysis of the identified studies with the snowball sampling approach, 40 papers were considered in the review. 40 social impacts of CE were found within the literature. About half of them were positive and the other half negative. The authors found that positive impacts for some stakeholders could imply negative consequences for others, e.g., job creation in one region might lead to a decline in job opportunities in other regions. To assess CE, 104 single social indicators and 9 composed indicators were identified. Most of them could be linked to stakeholder groups and subcategories proposed in the UNEP S-LCA guidelines (UNEP, 2020). Training and education, job creation, as well as health and safety were relevant identified indicators in the context of CE. S-LCA has rarely been used in the assessment of CE strategies so far and needs to be standardized for application in the industry. Not all social impacts of CE are addressed by existing indicators. This, and the fact that not all circularity indicators that address social consequences of CE (social circularity indicators) are covered with S-LCA, reveals the need to suggest and harmonize additional subcategories that are especially relevant for CE. The authors propose to apply and integrate the identified social circularity (inventory) indicators in future S-LCA studies to assess CE concepts.

ItemFifth-generation district heating and cooling systems: A review of recent advancements and implementation barriers(PERGAMON-ELSEVIER SCIENCE LTD, 2023-01)As global urbanisation levels continue to rise, supplying urban areas with low emissions energy becomes imperative in the fight against climate change. In areas with high demand density, district heating and cooling systems are generally a more efficient alternative compared to individual solutions, but current systems are mainly powered by fossil fuels and suffer from significant thermal losses due to high operating temperatures. Fifth-generation district heating and cooling systems (5GDHC) is a promising technology, able to address these drawbacks. 5GDHC systems operate at near ambient temperature, ensuring efficient integration of renewable energy sources and waste heat recovery potential. Their ability to provide simultaneous heating and cooling through the same pipeline and bidirectional energy flows allow for load balancing through the harvesting of demand synergies between different users. 5GDHC systems can play an important role in the energy transition but not much is known about their environmental performance over their life cycle and the novelty of the concept means that planning and design guidelines are scarcely present in the literature, hindering their development and further adoption. This study critically reviews recent advancements in the relevant literature as the 5GDHC technology transitions from research and development to the demonstration phase. Moreover, the paper addresses the design parameters and methodologies encountered in the literature for the modelling and operation of 5GDHC systems. Finally, the economic and environmental performance are discussed while presenting an overview of future developments and challenges related to full-scale deployment.

ItemIntegrating embodied greenhouse gas emissions assessment into the structural design of tall buildings: A framework and software tool for design decision-making(ELSEVIER SCIENCE SA, 2023-10-15)Urgent changes are needed in the construction industry to address the adverse effects of material production on the environment. The construction of tall buildings results in a high temporal and spatial concentration of greenhouse gas (GHG) emissions. This is largely due to the compounding influence of wind and earthquake loads on structural material requirements. Thus, to meet short-term climate change mitigation goals, the structural design of tall buildings must consider and minimise the embodied GHG emissions of structural systems. This study aimed to develop a framework to inform the design of tall building structural systems in order to minimise their embodied GHG emissions. A software tool was developed to implement the framework and automate the design, analysis, and embodied GHG emissions assessment of structural systems for tall buildings. Approximately 1,000 building models were iteratively designed, analysed, and assessed using the software tool. Through regression analyses, the resulting dataset was used to construct predictive models for the embodied GHG emissions of 12 unique combinations of structural system typologies and materials. By applying the framework and software tool to a 52-storey case study building, it is estimated that optimising structural material choices and geometric design strategies could reduce the embodied GHG emissions of tall building structural systems by up to 20% compared to current practices. The developed framework and software tool allow designers to use environmental assessment as a design decision-making tool, rather than an appraisal method for evaluating completed buildings, helping to reduce the environmental effects associated with tall building construction.

ItemAn exploration of public perceptions of place character in the Pathuriaghata neighborhood of Kolkata, India(AMPS (Architecture, Media, Politics, Society), 2023)People living in one location for a considerable period of time often form what has been termed ‘place attachments’ to those locations and their associated features. In historic cities continuously inhabited by generations of people, long-time residents interact with the landscape settings, associating meanings, uses, and values to different landscape features to form person-place bonds, such that these features in the landscape become integral to their own sense of personal identity― Proshanky has termed this as ‘person-place identity’ since it conveys the person’s own aspect of individual identity that gets mediated by the physical environment and the meanings and values associated with particular places and associated features to which they have become attached. In this way certain features in the landscape can serve as perceptual cues that remind residents of where they belong and who they are and can become ingrained as their ‘place-memory’. As early as 1925 it was suggested by Maurice Halbwachs that landscape features in a place are not remembered in isolation, but together as ‘collective memory’ of a landscape setting. Groups of people residing in one place for long periods of time can share similar memories and person-place bonds that give rise to ‘cultural memories’ allowing the ‘concretion of identity’ of a place to occur. This is experienced as the distinctive ‘feel’ or ‘character’ of a place as expressed by its landscape and associated place features, people, history, and ways of life. In the case of any historic city, historical urban patinas collage together conveying place identity through cultural memory that is often of heritage value and an important resource for sustaining good quality of life. Natural and cultural (tangible and intangible) heritages support the livability of residents through providing sustainable local economies, traditional livelihoods, use of local resources in traditional arts and crafts, and environment-friendly methods of construction. According to the ICOMOS Burra Charter 1999 “places of cultural significance enrich people’s lives, often providing a deep and inspirational sense of connection to community and landscape, to the past and to lived experiences”; this charter further suggests that changes to such places should entail “as little as possible so that its cultural significance is retained.”

ItemExploring residents' definition and use of neighbourhood leftover spaces in Colombo, Sri Lanka(Amps (Architecture, Media, Politics, Society), 2023)Urban leftover spaces are the residual spaces or cracks in cities that form due to rapid urban development. "urban voids" These types of spaces have also been referred to as "lost spaces", "loose spaces", They are typically vacant, neglected, or underutilized spaces within highly urbanized areas and can be permanent or temporary. They are often considered urban spaces awaiting future use. and "informal urban green spaces". These types of spaces have been studied for over five decades, with much of that research aimed at understanding their characteristics and potential uses in urban environments. The specific socio-economic and environmental context in which the spaces occur often influences the results. While these spaces occur at different urban scales and land use zones, their presence at the neighbourhood level has often been overlooked. Furthermore, although interest in these spaces has dramatically increased in recent years, their specific uses and definitions are often unclear due to the various ways they are interpreted and perceived.

ItemCommunity-perceptions of place-character and associated meanings in the context of a contemporary cultural landscape: the case of the historic neighbourhood of Pathuriaghata in Kolkata, India(AMPS (Architecture, Media, Politics, Society), 2023)In 1925, Carl Sauer defined a cultural landscape as the “union of physical and cultural elements of the landscape” wherein “cultures … grow with original vigor out of the lap of a maternal natural landscape, to which each is bound in the whole course of its existence.” In 1992, for the first time, UNESCO considered cultural landscapes as holding Outstanding Universal Values (OUV) based on heritage values and promoted the idea of the necessity of protecting such landscapes. Cultural landscapes are shaped through the interaction between humans and the natural geography of places wherein different features in these settings become associated with human activities, memories, and histories over time, thereby accruing meanings and values. Such human-nature interactions contribute to specific settings' place identities. Place identity represents that part of people’s self-identity is defined by elements within their everyday environment to which they are affiliated. Communities living in a particular cultural landscape for a considerable period often share similar perceptions with others inhabiting the same landscape setting. They form emotional bonds, or place attachments, with key features in the landscape that others can also share in the same environment. As places and their societies evolve, new meanings and values concerning the landscape emerge, adding new features to urban landscapes, often transforming valuable heritage settings to ones of global uniformity devoid of deep meanings. Over time, important features in the landscape develop patinas and coexist as collective memories that convey meanings and values from different periods referred to this as the collective historic urban fabric composing a ‘collage city’, suggesting that places with distinctive identities can transform over time the image of a city, within cultural landscapes. Rowe and Koetter over generations, to attain heritage value for society. thereby defining ‘cultural identities’ Identifying the tangible and intangible cultural and heritage value associated with landscape features can provide clues as to what is most important to be conserved to maintain the distinctive character of the place into the future and, conversely, what might be able to be sacrificed for newer development.

ItemMeasuring the Australian Night Time Economy 2021-22(Council of Capital City Lord Mayors, 2023)This report provides the latest insights into the Australian Night Time Economy (NTE) during the 2021/22 financial year. During this time, businesses continued to experience considerable restrictions and uncertainty, leading to significant fluctuations in activity. The start of the financial year began with lockdowns and restrictions – particularly in the eastern states and the Australian Capital Territory – but by January 2022 most Australians had been vaccinated and the nation had begun its transition towards ‘living with COVID’. As restrictions lifted, Core NTE businesses provided an opportunity to draw people back to our cities, enabling Australians to socialise and spend some of the savings they had accumulated during the pandemic. Core NTE businesses showed considerable innovation in navigating pandemic restrictions and adapting to evolving consumer habits. Although Core NTE businesses were able to trade again, they faced challenges such as staff shortages, changes in footfall patterns (contributing to demand unpredictability) and reduced lead-times for bookings. Some of these challenges persist in 2023. These challenges and opportunities have prompted states, territories and local governments to recognise and promote the advantages of fostering safe and vibrant NTEs through actively pursuing strategies, action plans and partnerships to support their development. This year’s report provides details on some of the initiatives that local governments have been implementing in their cities. It then analyses the economic performance of the sector – beginning with an overview of Australia, followed by a summary of trends in the states and territories and detailed analysis for each participating CCCLM member city (although detailed data has been prepared for 88 Australian cities, with a high level summary provided in Table 5, page 77). In many cases, Core NTE businesses have experienced growth in sales turnover in 2021/22, however, above average inflation is a factor in this performance; with the cost of goods and services in 2021/22 4.4% higher than in 2020/21 and 7.6% higher than in 2018/19 – an important factor to bear in mind when reviewing results. This report introduces more localised and unique insights for cities, via temporal analysis using the data behind Google Maps. This data complements the economic analysis by providing an understanding of where night time businesses cluster and the typical trading patterns of consumer-facing business activities in each city. Through 2022/23 and beyond, continued increases in inflation and associated cost pressures – on businesses and individuals – will continue to affect the NTE, and there is already evidence that while recent consumer spend has improved, this is driven more by use of credit than debit cards. The growing interest in the NTE from both the public and private sectors, combined with the latest evidence and insights provided in this report and other datasets, should support the sector going forward.
