Design for Deconstruction Through Digital Fabrication of Thin Spatial Systems
Authors: Iuorio Ornella , Wilcock Sam , Korkis Emil 
Published: May 2024

AbstractSpatial systems like shells, arches and shelters can often be used as temporary structures to accommodate short to medium expositions, events, or emergencies. This has historically allowed them to be designed for multiple uses. Recent advancements in computer graphics, algorithmic design, and advanced manufacturing have accelerated their development and opened new scope for applications, by exploiting new capabilities and opportunities for material-efficient designs and constructions. The authors aim to develop combined systems approaches to the design of resilient, de-constructible constructions for the built environment. This work presents the recent advancements in the development of discrete shell systems developed at the AS_Lab between the Politecnico di Milan and the University of Leeds, using biogenic materials such as wood which are inherently sustainable. Coupling geometry design and segmentation with ad-hoc connection systems, demountable systems have been developed, which are materially efficient, digitally designed, and fabricated, and can, in some instances, be robotically assembled. The study presents the conceptual design and fabrication of three prototypes, which have been realized to accelerate the transition to industry 4.0 while posing the focus on a circular future.
Circular Economy in Construction: Harnessing Secondary Materials from End-of-Life Tires for Sustainable Building
Authors: Qin Xia , Kaewunruen Sakdirat 
Published: May 2024

AbstractThe concept of the circular economy has rapidly gained traction as a transformative approach to sustainable resource management. Central to this paradigm is the emphasis on recycling and repurposing waste materials to ensure their maximum re-utility and minimal environmental side-impact. Over the myriad of waste materials, end-of-life (ELT) tires have emerged as a particularly significant resource, which has been underestimated in the past. However, the advent of advanced recycling technologies has illuminated the latent value embedded within these tires. From their rubber granules and steel components to fibrous materials and carbon black, each element holds potential for repurposing. Notably, the construction industry has been identified as a prime sector for the integration of these recycled materials, offering both durability and sustainability in building processes. Guided by the principles of the circular economy, this paper embarks on a comprehensive journey through the full lifecycle analysis of ELT tires. It delves into the intricacies of the recycling and utilization processes, shedding light on the myriad of potential value they present. Furthermore, a meticulous assessment and review are conducted on the contribution of these recycled tire by-products to the construction industry. The study revealed that recycling tires can result in a reduction in carbon emissions and provide substantial economic benefits. Specifically, for truck tires, the economic benefits can amount to 32.37 €, and the GHG emissions produced during the recycling process are minimal, only 1.13 kg of CO2 equivalent for truck tires.
Stakeholder Mapping for Value Creation of New Circular Business Models
Authors: Haase Matthias , Bernegger Heinz , Meslec Mihaela 
Published: May 2024

AbstractIn Circular Economy Management, various stakeholders play different roles that contribute to the value chain within the circular economy. These stakeholders need to be tracked and motivated to contribute to a circular economy. In addition, real estate developers as well as facility managers have a growing interest in both, the expansion of the value chain within the building as well as associated with facility services within the optimized building operation. The research approach is drawing upon real estate development projects as case studies. It maps the different stakeholders and analyses their role in the value creation. A range of new value creation stakeholders were identified and analysed to which extend their role is defined in traditional business models. The key benefits for owners and real estate investors comes from the adaptability to changing market demands, re-use and repurpose, low impact on urban ecology and biodiversity, innovative new real estate products among others. This study shows the benefits of encouraging stakeholders to actively participate in the co-creation and co-innovation of circular solutions. This involves identifying different stakeholders in the design and development of strategies, policies, and projects related to the circular economy. By defining their new role, diverse business models, as well as innovative and effective solutions can be developed.

AbstractThis study examines the importance and adoption of circular economy (CE) principles within the construction industry by focusing on stakeholders’ opinions on key CE strategies across different building life cycle stages. The study draws insights from the perceptions of European-based stakeholders who actively participated in the CircularB Workshop 1 Part 2, entitled Creating a Roadmap towards Circularity in the Built Environment - State-of-the-Art. The research comprises two parts. In the first part, a structured survey was employed to systematically collect opinions on the levels of awareness and variations among the adoption and importance of selected CE implementation strategies within the construction sector. The second part engaged stakeholders in a dynamic creative thinking activity, posing seven targeted questions allowing participants to offer multiple answers for each query. Overall, the study sheds light on the multifaceted challenges and opportunities inherent in fostering CE within the construction domain by highlighting the significance of recognising and addressing systemic barriers within the CE framework, the importance of product design for disassembly, and the efficient production of reusable and recyclable materials. Furthermore, it emphasises the necessity to motivate industry stakeholders to participate actively in the transition to a CE, bridging the gap between theory and practice frameworks and increasing the engagement of policymakers and governments.
Investigating Urban Resilience Through a Resource-Based View Framework: Evidence from an Empirical Survey
Authors: Scozzi Barbara , Pellegrino Roberta , de Trizio Alessia , Di Lonardo Monica 
Published: May 2024

AbstractUrban Resilience refers to the ability of a city to absorb, adapt and transform in the face of a disturbance. Such a concept is increasing in importance as the continuous growth of cities leads them to face new uncertainties, challenges and often significant disruptions. Most extant literature focuses on the development of frameworks and indices that measure urban resilience. However, due to the inherent complexity of the concept as well as to the variety of research perspectives, the existence of several frameworks is quite confusing. Also, such frameworks fail to reveal how different urban factors affect resilience and the way it acts on the urban scale. The study aims to contribute to address such limits by investigating the main urban characteristics affecting resilience. Using a Resource-based view (RBV) perspective, the research develops a theoretical framework which links resources of urban systems (economic, social and environmental), urban abilities (leadership and governance, preparedness, cooperation and infrastructures and resources), and resilience capacities (absorptive, adaptive and transformative). The theoretical framework is then empirically tested through an online survey sent to a sample of urban stakeholders, namely, policy makers, emergency services, public organizations, academics, experts, infrastructure employees, public and private associations and organizations. The empirical analysis provides scholars with knowledge on the main factors that affect resilience and enables policy makers to better understand the way urban resilience arises based on the interrelationship between urban resources and capabilities.

Published: May 2024

AbstractOne of the major motivations behind the effort for the transition from linear models to circular ones in the building sector is related to the need for the minimization of resources depletion. Water holds a prominent position among those resources. The building sector is responsible for appreciable water consumption and, hence, represents an important field for improvements. While in the case of new buildings several options are available for the relevant systems and strategies, when existing buildings are considered, the limitations are multiplied in the context of decisions already made and materialized. However, the existing building stock is a massive contributor to the total impact of the built environment and must be considered as well. In this work, three buildings’ environmental performance assessment methods (BREEAM, DGNB, LEED) and, specifically, their versions for existing buildings in use (residential and non-residential), are examined regarding the way water-related parameters are implemented in the evaluation that they perform. The factors reviewed are those associated with water regarded as a resource (water consumption, (re-)use of rainwater, management issues etc.) and not the ones referring to flood risks and to energy demand (hot water). The analysis’ main focus lies in the criteria used by each method, the main strategies highlighted as advantageous, and issues related to the integration of those evaluation axes into each system. Initially, main features of the three methods are presented (assessment structure, scoring process, etc.). Among others, differences and similarities in the adopted approaches (three evaluation methods, various building uses) are highlighted and discussed.
Decarbonization Possibilities for Affordable Timber Houses. An LCA Comparison of Business as Usual and Circular Strategies
Authors: Passarelli Rafael Novais 
Published: May 2024

AbstractTo better understand the full impact of building materials and buildings over their lifetime and beyond, Lifecycle Assessment (LCA) studies have been an area of interest and a growing body of knowledge. Moreover, recent studies emphasize the critical importance of the end-of-life (EoL) scenario, particularly for wood-based construction, and highlight its potential for further decarbonization through circular strategies. However, there is a significant knowledge gap in the LCA literature regarding mitigation strategies specific to affordable housing options, despite the urgent and undeniable need for these typologies worldwide. This study contributes to filling this gap by conducting a materials-level, whole-building LCA of a prototype affordable single-family house built in 2020 using a business-as-usual wood-frame construction method. Besides the conventional as-built scenario, this study developed five hypothetical scenarios that evaluated the influence of different EoL options (recycling or energy recovery), enhanced circular strategies (reduce and reuse), and substitution of non-renewable materials with circular materials for insulation (wood fiber) and finishing (clay plaster), with the aim of identifying further opportunities and limitations for decarbonizing such a typology and construction method. The results of this study consistently indicated that the order of priority should be to (1) ensure appropriate end-of-life for metals and wood-based materials. (2) Replace non-renewable materials with renewable wood or earth-based materials. (3) Improve material reuse and construction waste diversion rates. The results of the study could support decision-making processes for the design and construction of low-impact affordable single-family homes and the development and implementation of affordable housing policies and regulations.

Published: May 2024

AbstractSignificant changes in the strategic goals of the construction sector at the global level have been visible in recent years. By implementing the fundamental principles of sustainable development and circular economy, the modern construction industry tries to contribute to a healthier environment by reducing CO2 emissions, minimizing waste landfills, and preserving non-renewable natural resources. The possibilities of reusing prefabricated concrete elements of existing buildings instead of their traditional recycling on a material level or disposing of them in landfills are analyzed in this paper. Special attention in the research was placed on the carbonation of prefabricated reinforced concrete elements of buildings, as it is one of the most frequent processes that accelerate the deterioration of RC structures. Long-term carbonation processes inevitably result in reinforcement corrosion and accompanying damage to the concrete cover, therefore some constrains for the further use of prefabricated RC building elements must be precisely defined. In this study, the potential use of prefab RC building elements was determined by calculating the depth of carbonation while taking into account the age of buildings and environmental conditions (relative air humidity, position of prefab element). Depending on the thickness of the carbonized concrete and the type and intensity of damage to the reinforcement and concrete, various variants for further use of the dismantled prefabricated RC building elements were proposed (reuse without restrictions, use in the interior of new buildings, use in less demanding facilities, reuse after application of a protective coating, replacement of the protective cover and reuse etc.).

Published: May 2024

AbstractThere is a growing emphasis in current global construction sector for the incorporating of sustainability ideas into design and construction practices. This present paper investigates the considerable impact of using Building Information Modelling (BIM) techniques to address sustainability and financial concerns in a residential project in the Kingdom of Saudi Arabia (KSA). We propose to further embedding BIM 3D modelling and the development of alternative design scenarios for optimising Life Cycle Cost (LCC) and Life Cycle Assessment (LCA). Four scenarios are assessed using Green Building Studio (GBS) for whole-building analysis, and specific design units are assessed using One Click LCA, which is integrated into Revit. The significance of the study relies on merging of BIM and LCC to improve the sustainability of residential developments at the KSA. It also intends to optimise resource efficiency, reduce environmental impact, and increase cost-effectiveness throughout the whole life cycle of residential structures by using simulation approaches. The findings will benefit industry stakeholders by encouraging sustainable practises that inform decision-making processes in the context of Saudi residential development.
Designing Musical Instruments and Room Acoustics with Acoustic Metamaterials
Authors: Bader Rolf , Kontopidis Patrick 
Published: May 2024

AbstractMechanical musical instruments have less timbre variability than electronic instruments. Extended playing techniques and more sophisticated acoustic instrument designs have recently appeared. We suggest acoustic metamaterials as a new way to extend the timbre of mechanical instruments beyond their present sound capabilities. In this chapter, we present three examples of acoustic metamaterials: (1) a one-dimensional string, (2) a labyrinth sphere, and (3) a two-dimensional membrane. The string is covered with additional masses, which leads to a dispersion relation of the harmonic overtones in the sound spectrum. The resulting sound still has a detectable pitch but is very different from a regular string on a mechanical instrument. The labyrinth sphere has a clear band-gap damping and can be used in loudspeakers, musical instruments, or room acoustics due to its small size. A circle of masses is attached to the membrane, leading to a cloaking behaviour of vibrations from within the circle to outside and vice versa. Again, the resulting sound is considerably different from a regular drum and leads to increased variability of musical articulations. Using a microphone array, laser interferometry, impedance tube, and high-speed video recordings with subpixel tracking, the vibrations on the string and the membrane are investigated and discussed in relation to new instrument designs.
Exploring Musical Agents with Embodied Perspectives
Authors: Erdem Çağrı 
Published: May 2024

AbstractThis chapter presents a retrospective of five interactive systems I have developed focusing on how machines can respond to body movement in music performance. In particular, I have been interested in understanding more about how humans and non-human entities can share musical control and agency. First, I give an overview of my musical and aesthetic background in experimental music practice and a less conventional approach to sound and music control. Then follows a presentation of embodiment and music cognition theories that informed the techniques and methods I employed while developing these systems. Then comes the retrospective section structured around five projects. Biostomp explores the unintentionality of body signals when used for music interaction. Vrengt demonstrates musical possibilities of sonic microinteraction and shared control. RAW seeks unconventional control through chaos and automation. Playing in the “air” employs deep learning to map muscle exertions to the sound of an “air” instrument. The audiovisual instrument CAVI uses generative modeling to automate live sound processing and investigates the varying sense of agency. These projects show how an artistic–scientific approach can diversify artistic repertoires of musical artificial intelligence through embodied cognition.
Sound Design and the Theory of Self-augmented Interactions
Authors: Leman Marc 
Published: May 2024

AbstractIn the past decades, musicology has been evolving at a pace that matches new developments in technology. Underneath this development, a new theory of music emerged, embracing interaction states as a model for understanding how music can be empowering. In the present chapter, sound design is considered from the viewpoint of interaction states, using caregiver–infant communication as a challenging domain of application. Sound design components of interest are identified, as well as human capacities for dealing with them in terms of empowerment. These are related to the concepts of self-augmented interaction and biofeedback-based sound design.

Published: May 2024

AbstractThe growing prevalence of digital learning in higher education is accompanied by challenges regarding students’ self-regulated learning. While there is a plethora of behavioral interventions that aim at supporting students’ self-regulated learning, they often do not consider the heterogeneity of students in their intervention design. This paper presents a novel feedback intervention that leverages the potential of machine learning and counterfactual explanations for providing personalized feedback to support students’ learning. Ultimately, this approach could automatically adapt to different courses and thereby empower scalable and effective feedback.
