Authors: Huyen Nguyen Thai , Take Kenzo , Take Kyoko 
Published: October 2024

Abstract
The buildings and construction sectors play a pivotal role in combating climate change. Globally, they account for 30% of the final energy consumption and 27% of total energy sector CO2 emissions. Buildings currently consume up to 40% of the world’s total energy, and it is projected to increase to 50% by 2030. The world faces a significant challenge in addressing these issues related to global energy production. From the Paris Agreement in 2015 to the United Nations Climate Change Conference in Glasgow (COP26),Japan has committed to developing and implementing robust greenhouse gas (GHG) emission reduction measures using its resources. They have declared their intention to achieve carbon neutrality by 2050, improving the energy efficiency of structures. This involves measures such as regulating electricity usage, imposing restrictions on design specifications concerning the built environment and raw materials and promoting the use of sustainable energy sources to minimize the environmental impact of buildings. These efforts have given rise to the concept of net-zero energy buildings (ZEB) and net-zero energy housing (ZEH). This paper aims to provide a comprehensive review of ZEB/ZEH in a general context and to assess its feasibility and practicality within the specific context of Japan.

Published: October 2024

Abstract
The European energy transition is currently emphasizing advancements in regulations and technologies, with a focus also on social justice. Citizens are perceived as key players in the energy systems, as their direct involvement can contribute to the wide spread of improved behaviours and clean energy production. This paper explores Community Transition Pathways (CTPs), an innovative instrument to support energy citizenship effectively. CTPs guide citizens through structured paths, addressing diverse communities. Grounded in energy citizenship theories, the concept integrates insights from literature and policy developments. CTPs have been created within the H2020 project GRETA and verified in six case studies across Italy, Spain, Germany, the Netherlands, and Portugal. This paper aims to present the instrument as a project result, embedding its creation in the current debate about energy citizenship and transition pathways and presenting the results on three GRETA case studies. The research’s originality lies in its empirical approach, emphasizing citizens’ active roles in transition processes. Successful development and testing of CTPs demonstrate their value in fostering collaboration in clean energy production and facilitating participatory transition paths. However, ongoing refinement and replicability are essential for sustained success. By positioning citizens as active participants and reshaping public decision-making, CTPs advance a more inclusive and impactful approach to energy transition.
Flood management in the built environment: the micro-scale contribution to a distributed strategy
Authors: Vanelli Francesca , Lavagna Monica , Minifie Paul 
Published: October 2024

Abstract
The built environment offers an opportunity to implement Flood Risk Management measures by spatially distributing them as a complementary alternative to large-scale protection schemes. Specifically, micro-scale solutions focus on buildings, open spaces, users, and small infrastructure, addressing various flood management strategies with different performance indicators. These measures encompass, for instance, private precautionary measures like floodproofing or elevation, and nature-based solutions. However, their adoption faces technology, economics, and social challenges. To effectively reduce flood risk and increase the built environment’s resilience to floods, a systemic approach is necessary, evaluating and jointly implementing diverse measures across the built environment. Drawing from a systematic literature review and expert interviews, this study explores micro-scale Flood Risk Management measures within the built environment, examining their barriers and drivers. Additionally, it introduces an atlas of multi-strategy measures, qualitatively comparing their performance. The paper concludes by emphasizing the need for a holistic perspective on flood adaptation and highlights opportunities to enhance building-level adaptation actions through collaboration with various stakeholders.
How water circularity can help to reduce and regulate water waste in urban districts
Authors: Tucci Fabrizio , Baiani Serena , Mancini Francesco , Romano Giada , Maria Giannini Lidia 
Published: October 2024

Abstract
Global water consumption has increased sixfold in the past 100 years and is growing at about 1% per year due to population growth, economic development, and changing consumption patterns; therefore, climate change, combined with urbanization and population growth, is causing water availability problems in cities around the world. Rethinking circular cities that put water at the centre of their priorities and that manage it cyclically and keep it within the urban environment as much as possible to maximize its value must become the fundamental goal. However, to date, cities are not even close to maximizing the use of water that reaches their buildings. As a result, two main issues have emerged as crucial in the international debate: the scarcity of water resources due to its wastefulness and overuse, and extreme weather events, such as heavy rains alternating with periods of prolonged drought, a consequence of global warming. In response to these issues, this research aims to investigate the potential of a design approach that takes into account the two phenomena of water excess and shortage, integrating water from the earliest decision-making stages of building design. Starting from the definition of architectural strategies, replicable solutions are defined and evaluated against specific KPIs to develop a resilient and climate-neutral architectural and urban design model.

Authors: Emre Kaya Fuat , Monsù Scolaro Antonello 
Published: October 2024

Abstract
This paper employed the System Dynamics (SD) methodological tool to investigate the intricate dynamics of transitioning to the circular economy, as a climate change mitigation strategy, in the building sector while focusing on stakeholder dynamics throughout the building life cycle. This paper’s methodological approach used a two-stage approach, encompassing problem articulation and formulation of dynamic hypothesis. In the problem articulation stage, this paper identified the stakeholder dynamics in the building life cycle thanks to a comprehensive critical literature review. This paper then delved deeper into the stakeholder dynamics in the formulation of dynamic hypothesis stage. The results revealed that the stakeholders are interdependent while working together to address common concerns. Furthermore, the results emphasized the importance of stakeholder collaboration and communication in overcoming barriers to the circular economy transition in the building sector. Thus, this paper aims to contribute to the understanding of stakeholder dynamics while streamlining the decision-making process and suggesting potential solutions for the effective implementation of the circular economy in the prevailing linear state of the building sector to pave the way for a collaborative and communicative approach to climate change mitigation. While recognizing the limitations, this paper suggests future research for a more comprehensive analysis of the complex system’s dynamics.

Authors: Mohamed Rahla Kamel , Bragança Luís , Mateus Ricardo 
Published: October 2024

Abstract
The Circular Economy (CE) emerged in the last decade as an imperative path to transition towards more sustainable practices and go beyond carbon neutrality. Applying CE principle in the built environment has been investigated and recent research advocated for positive impacts if the sector embraces the paradigm shift and moves away from linear towards more circularity. Similarly, the literature regarding Circular Business Models (CBMs) has witnessed substantial growth as the latter holds the promise of providing a blueprint on how to make a financial profit while applying CE principles. Nonetheless, a gap remains in understanding the actual impact of CBMs in the built environment from a sustainability perspective. This paper will explore current literature regarding the environmental, economic, and social impacts of CBMs in the built environment to address this gap and provide a clearer understanding of the dynamics of circularity and sustainability. This exploratory research will provide valuable insights into the effectiveness of CBMs in fostering sustainability within the built environment.
Reducing the embodied carbon using bio-based building materials: the biogenic carbon content of timber
Authors: Giacomello Elena , Perrucci Giovanni , Trabucco Dario 
Published: October 2024

Abstract
In recent decades, several efforts have been made towards the reduction of operational energy and therefore carbon, thanks to the introduction of mandatory compliance in many national regulations, achieved by using specific certification tools. As operational carbon diminishes, the significance of embodied carbon - emissions released before the building and infrastructure begins to be used - will continue to increase as a portion of total emissions.
Strategy for reducing embodied carbon include the use of building components derived from plants, which absorb atmospheric carbon during their growth through photosynthesis. Wood stands out among building materials, not only for its ability to store biogenic carbon but also for its lower emissions as per life-cycle assessments (LCA).
The purpose of this paper is to conduct an LCA of a wooden building using a Whole-Building Life Cycle Assessment (WBLCA) software, and to explore three methodologies for assessing biogenic carbon in LCA. It follows the two primary calculation methods provided by the EN 15804 and ISO 21930 standards for LCA, along with an additional “dynamic approach”.
Key procedural discrepancies between the explored methodologies arise, guiding designers to adopt varying strategies in minimising a building’s carbon footprint. This research aspires to underscore the shortcomings and advantages of prevalent methods.
Bespoke metal cladding. Rethinking the design of the building envelope to ensure sustainability principles
Authors: Scanagatta Chiara , Condotta Massimiliano 
Published: October 2024

Abstract
Nowadays policies are increasingly oriented towards the use of renewable and bio-based materials to reduce the environmental impact of the building sector. Furthermore, the increasing use of dry construction techniques allows to combine a more sustainable use of resources with an attentive management of the end-of-life stage. Considering the need to shift the demand for material sourcing towards solutions that do not permanently affect the environment, the use of metals is not the first solution that comes to mind, but it offers many possibilities both in terms of sustainability and formal rendering. Metals can have great potential for use but, although the benefits of recyclability and disassembly of this material are well known, the metal cladding sector still finds little room for development. Bearing this in mind, this contribution presents a research work which analysed the possibilities and opportunities deriving from the use of metal cladding for sustainability.
Circular Economy in Heat Supply Systems for Buildings: An Overview of the End of Life of System Components and Existing Evaluation Systems and Products
Authors: Pichlmeier Franziska 
Published: October 2024

Abstract
In order to achieve climate protection targets, many heating systems must be converted to renewable energies and more efficient systems. Most of residential buildings in Germany are heated with natural gas (50 %), 25 % with an oil. Around 45 % of the heating systems are older than 15 years, 20,5 % are even older than 25 years. Therefore, a high replacement rate is to be expected in the next few years. In the context of circular economy, the accumulating materials should remain in the material cycle. Some materials, such as metals, can be recycled easily. However, building services engineering, in particular heat supply, has become increasingly complex. This paper focuses on the state of the circular economy of heat supply systems for buildings. Firstly, a detailed examination of products utilized in heat supply systems is undertaken. Secondly, an assessment of the end-of-life scenarios for these components was conducted, considering disposal routes and recycling rates. Lastly, an evaluation of assessment systems fostering a circular economy regarding heat supply systems is performed. The aim of the work is to provide an overview of the state of the art with regard to circular economy in heat supply and thereby draw conclusions as to where potentials and obstacles exist.
Assessment methods and digital tools to support circular building strategies
Authors: Giorgi Serena 
Published: October 2024

Abstract
The aim of the paper is to highlight how digital technology can be a vector for maintaining information of buildings products, promoting supply chain transparency and traceability of materials and environmental data, contributing to activate a sustainable circular economy. Indeed, the current lack of knowledge of product characteristics often hinders the activation of reverse logistic and the assessment of the environmental benefits of circular material flows. This means, on one hand, the need to trace and collect product characteristics and product environmental information throughout the entire life cycle, and, on the other hand, the to identify ways of communicating and sharing information. This paper outlines current digital tools to support transparency and traceability of materials. Next, the paper verticalises the method and indicators used to declare the circular and sustainable profile of products, emphasising the importance of applying Life Cycle Assessment (LCA). Finally, the prefiguration of a possible integration between traceability tools and the LCA methodology is discussed, identifying possible drivers (e.g. legislative, trainings) and possible key-operators for the widespread of the “LCA-integrated traceability tools”.
Water and Carbon Neutral Buildings: systemic approaches and hybrid strategies
Authors: Violano Antonella , Harputlugil Timuçin 
Published: October 2024

Abstract
In order to achieve a real green transition in the design, construction and use of the built environment, especially in contemporary urban contexts, it is necessary to assess the water saving benefits combined with binding energy efficiency and climate neutrality targets in a holistic manner. This approach cannot focus on stand-alone requirements. Special emphasis is placed on technological solutions that transform energy and water consumption from negative to positive at all stages of the life cycle, including construction and operation. The aim is not just to reduce expenditure, but to increase the effectiveness of the savings through an effective and cyclical approach over the long term.
This paper presents the results of a research project that develops a set of integrated indicators in accordance with the Itaca Protocol standard, UNI/PdR Practice 13.0:2019, with the introduction of elements from the Level(s). The environmental indicator system is designed to simultaneously assess the requirements of water-neutral and carbon-neutral construction, in line with EU recommendations C/2021/2279 and C/2021/9332. The hybrid water-energy strategies used in the application of this system are evaluated in terms of their potential to achieve the aforementioned goals. This approach, illustrated by best practice examples, aims to provide a holistic assessment of the environmental performance of integrated buildings in contemporary urban contexts, taking into account both water efficiency and carbon reduction. The objective is to guide the technological design and construction of sustainable buildings, promoting a synergetic approach to water and carbon footprint management, starting from the case study of a building in Palermo.

Published: October 2024

Abstract
In the last decades, significant efforts have been made in urban construction to achieve rapid economic development. However, with climate change on the agenda, there is a growing recognition of the importance of urban sustainable development and of its potential impacts on residents. Reflection reveals that many policies, measures, and tools are inadequate; therefore, public open spaces are regarded as a potential target of urban regeneration strategies. This study explores users’ perceptions of public open spaces through participatory methods. The developed methodology is applied to specific areas of Lhasa, the major city of the Tibet region, which was selected as a test-bed site. The survey involved a selected pool of participants and emphasized the coverage of different types of public open spaces. Investigate factors including personal background, overall satisfaction, user evaluation, usage preference, and willingness to change, analyze key factors based on quantitative survey results. Subsequently, identify the key regenerative design elements that require highlighting. The findings indicate that comfort and safety are emphasized by users of all types of public open spaces. Additionally, their initial impression upon entering a space significantly influences their overall satisfaction with it. Besides, although individual background differences play a role, they are not sufficient to significantly influence the user’s evaluation of the space. However, variations in the purpose of space use result in differences in user evaluations and needs, impacting their attitudes based on the type of space. Finally, urban regeneration design strategies are proposed for various types of public open spaces and users.
Enhancing climate adaptation design in urban areas: a workflow for climate integrated impact assessment
Authors: Verde Sara 
Published: October 2024

Abstract
Nowadays, urban settlements face the simultaneous occurrence of environmental, natural, and anthropogenic risks. In this scenario, the contribution proposes the definition of an operational workflow for climate-integrated impact assessment, to support climate adaptation design at the urban and building scale. The methodological approach focuses on the evaluation of heatwave and pluvial flooding integrated impacts to identify urban hotspots. A testing case in Naples is proposed. The workflow represents an innovative tool, employing a multi-hazard analysis at the local scale to assess climate impacts considering both vulnerability and exposure components of the built environment. Grounded in an evidence-based approach, the proposed workflow acts as an effective support tool for decision-makers in the preliminary stages of projects, considering the interaction between impact analysis and climate adaptation design at the local scale. The contribution is developed within the research Partenariato Esteso PE3, RETURN project (multi-Risk SciEnce for resilient commUnities undeR a changiNg climate) - Spoke TS1 “Urban and metropolitan settlements” activities.
