Adaptive kinematic textile architecture
(2020) Wyller, Maria; Yablonina, Maria; Alvarez, Martin; Menges, Achim
The research presented in this paper explores how textiles can be formed into adaptive, kinematic spaces to be able to respond to its environment and users utilizing on-site, distributed, mobile robotic connectors. The project aimed at creating an adaptive system that consumes little energy while making use of textiles’ advantageous qualities - their lightweight, portability, and manipulability. This was achieved through the development of a bespoke on-material mobile machine able to locomote on suspended sheets of fabrics while shaping them. Together, the connector and the tectonic system compose a lightweight architectural robot controlled with a feedback loop that evaluates real-time environmental sensor data from the space against user-defined targets. This research demonstrates how the combination of mobile robotics and textile architecture opens up new design possibilities for adaptive spaces by proposing a system that is able to generate a significant architectural effect with minimal mechanical actuation.

Advanced timber construction industry : a quantitative review of 646 global design and construction stakeholders
(2023) Orozco, Luis; Svatoš-Ražnjević, Hana; Wagner, Hans Jakob; Abdelaal, Moataz; Amtsberg, Felix; Weiskopf, Daniel; Menges, Achim
There has been a multi-storey timber construction boom since the start of the millennium. While there is now a body of research on trends, benefits, and disadvantages of timber construction, there is not yet literature on the wider market or the impact of stakeholders on it. This research investigates the (i) architects, (ii) engineers, and (iii) manufacturers involved in the realization of 300 contemporary multi-storey timber buildings from an existing survey. The analysis is based on data sourced from stakeholder websites and the building survey. It evaluates the perceived level of timber expertise of stakeholders based on service categorization and stakeholder type and relates them to the buildings they worked on. The research uses quantitative methods to answer qualitative questions on the connection between architectural variety in timber construction and the stakeholders involved. Interconnectivity between stakeholders and projects is visualized in an interactive network graph. The study shows a segmented mass timber market with relatively few impactful design and construction stakeholders, mostly located in central and northern Europe. It also identifies fabricators as the largest group of innovators advancing the industry and enabling the construction of more complex projects. It reveals the importance of collaboration and knowledge sharing for the industry’s growth.

Advanced timber construction industry : a review of 350 multi-storey timber projects from 2000-2021
(2022) Svatoš-Ražnjević, Hana; Orozco, Luis; Menges, Achim
Throughout the last two decades the timber building sector has experienced a steady growth in multi-storey construction. Although there has been a growing number of research focused on trends, benefits, and disadvantages in timber construction from various technical perspectives, so far there is no extensive literature on the trajectory of emerging architectural typologies. This paper presents an examination of architectural variety and spatial possibilities in current serial and modular multi-storey timber construction. It aims to draw a parallel between architectural characteristics and their relation to structural systems in timber. The research draws from a collection of 350 contemporary multi-storey timber building projects between 2000 and 2021. It consists of 300 built projects, 12 projects currently in construction, and 38 design proposals. The survey consists of quantitative and qualitative project data, as well as classification of the structural system, material, program, massing, and spatial organization of the projects. It then compares the different structural and design aspects to achieve a comprehensive overview of possibilities in timber construction. The outcome is an identification of the range of morphologies and a better understanding of the design space in current serial and modular multi-storey mass timber construction.

Agent-based principal strips modeling for freeform surfaces in architecture
(2024) Chai, Hua; Orozco, Luis; Kannenberg, Fabian; Siriwardena, Lasath; Schwinn, Tobias; Liu, Hanning; Menges, Achim; Yuan, Philip F.
The principal curvature (PC) of a freeform surface, as an important indicator of its fundamental features, is frequently used to guide their rationalization in the field of architectural geometry. The division of a surface using its PC lines into principal strips (PSs) is an innovative way to break down a freeform surface for construction. However, the application of PC networks in architectural design is hindered by the difficulty to generate them and flexibly control their density. This paper introduces a method for PS-based reconstruction of freeform surfaces with different umbilical conditions in the early stages of design. An agent-based modeling approach is developed to find the umbilics and increase the degree of control over the spacing of PC lines. This research can effectively expand the application range of PS-based surface reconstruction methods for freeform architectures.

An assessment of the correlation between urban green space supply and socio-economic disparities of Tehran districts : Iran
(2021) Nasri Roodsari, Elmira; Hoseini, Parian
Contact with UGS (urban green spaces) is a critical element for urban quality of life and an essential aspect of environmental justice, so all citizens should be able to access UGS regardless of their social and economic condition. In this regard, several studies have shown a positive correlation between UGS justice with socio-economic status in different contexts. In recent decades, Tehran has also experienced much wider socio-economic inequalities, reflected in its spatial configuration. Therefore, this study explored the possible correlation between the UGS supply and accessibility in the 22 Tehran municipal districts and their socio-economic development level. For this purpose, UGS supply (per capita) and accessibility (areas within 800 m walking distance to UGS) indicators are used to assess the UGS justice in Tehran. The research data are drawn from official spatial and statistical data, analysed using ArcGIS. This quantitative data are converted into map layers to shape a basis for UGS assessment indicators in conjunction with socio-economic status. The findings show an unbalanced distribution of UGS in Tehran. However, the areas with highest socio-economic status are at an optimum level of UGS justice in relation to all 22 districts, but no direct correlation confirms the same results for areas with lower socio-economic status.

Autonomous robotic additive manufacturing through distributed model‐free deep reinforcement learning in computational design environments
(2022) Felbrich, Benjamin; Schork, Tim; Menges, Achim
The objective of autonomous robotic additive manufacturing for construction in the architectural scale is currently being investigated in parts both within the research communities of computational design and robotic fabrication (CDRF) and deep reinforcement learning (DRL) in robotics. The presented study summarizes the relevant state of the art in both research areas and lays out how their respective accomplishments can be combined to achieve higher degrees of autonomy in robotic construction within the Architecture, Engineering and Construction (AEC) industry. A distributed control and communication infrastructure for agent training and task execution is presented, that leverages the potentials of combining tools, standards and algorithms of both fields. It is geared towards industrial CDRF applications. Using this framework, a robotic agent is trained to autonomously plan and build structures using two model-free DRL algorithms (TD3, SAC) in two case studies: robotic block stacking and sensor-adaptive 3D printing. The first case study serves to demonstrate the general applicability of computational design environments for DRL training and the comparative learning success of the utilized algorithms. Case study two highlights the benefit of our setup in terms of tool path planning, geometric state reconstruction, the incorporation of fabrication constraints and action evaluation as part of the training and execution process through parametric modeling routines. The study benefits from highly efficient geometry compression based on convolutional autoencoders (CAE) and signed distance fields (SDF), real-time physics simulation in CAD, industry-grade hardware control and distinct action complementation through geometric scripting. Most of the developed code is provided open source.

Bauforschung an der Kathedrale Auxerre
(2005) Kimpel, Dieter; Hansen, Heike
Weihnachten 1999 fegte Sturmtief „Lothar” durch Frankreich und Süddeutschland und fügte der Kathedrale St. Etienne von Auxerre vor allem im Bereich des Langhauses erhebliche Schäden zu. Man kann die Bestürzung in Auxerre ermessen, wenn man bedenkt, dass die Stadt mit ihren rund 38.000 Einwohnern Eigentümerin dieser ehemaligen Domkirche ist, was schon unter normalen Verhältnissen eine große Last für die Kommune darstellt. Es gelang nun aber, eine auf zehn Jahre angelegte Restaurierungskampagne zu starten, deren Finanzierung zu je einem Viertel den staatlichen Monuments Historiques, der Region „Bourgogne”, dem Departement Yonne und eben der Stadt obliegt. Die Kathedrale St. Etienne von Auxerre im nördlichen Burgund wurde ab 1215 in gotischen Formen über einer frühromanischen Ostkrypta in immer neuen Bauetappen bis zur Mitte des 16. Jahrhunderts errichtet. Ihre Architektur und Bauskulptur ist zum Teil von außerordentlich hoher Qualität. Da es sich bei der Kathedrale außerdem um ein herausragendes Baudenkmal handelt, wurde als leitender „architecte en chef des Monuments historiques“ Bruno Decaris (Paris) mit der Planung und Überwachung der Arbeiten betraut.

Beyond values : how emotions, anthropomorphism, beliefs and knowledge relate to the acceptability of native and non‐native species management in cities
(2022) Straka, Tanja M.; Bach, Luise; Klisch, Ulrike; Egerer, Monika H.; Fischer, Leonie K.; Kowarik, Ingo
Managing non‐native species in cities is often controversial because these species can support both ecosystem services and disservices. Yet, how the acceptability of non‐native species management by the general public differs in relation to native species, to distance (i.e. close to residence and elsewhere) and among plants and animals is understudied. Furthermore, while values, beliefs and knowledge are often considered in this context, psychometric factors such as emotions and anthropomorphic views have received little attention. We surveyed 658 residents in Berlin, Germany, to assess (i) the acceptability of management actions differing in their severity for non‐native plants and animals compared to native species with similar traits, (ii) the influence of perceived distance of species (i.e. close to residence and elsewhere) and (iii) the predictive potential of psychometric (i.e. values, beliefs, self‐assessed knowledge, emotions and anthropomorphism) and socio‐demographic factors for this acceptability. Eradication (i.e. lethal control/removal) was generally the least accepted management action, but more accepted for non‐native than native species. Distance mattered for the acceptability of non‐native plant management with unspecified control action the most accepted management action close to residence. While values (self‐transcendence and conservation) mostly explained the acceptability of doing nothing and eradication, emotions related strongly to all management actions. Beliefs were more important than self‐assessed knowledge in relation to non‐native species management and beliefs about non‐native plants and animals were rated almost similar. Anthropomorphic views had predictive potential for plants and animals; that is, the stronger people held anthropomorphic views, the less they accepted eradication. Participants with a garden supported doing nothing with plants (native and non‐native) more than without. Results highlight the complexity of factors underlying the acceptability of management actions on species in cities. While values, beliefs and self‐assessed knowledge are important in the context of species management, other psychometric factors add to our understanding of acceptability. We conclude that awareness about different acceptability patterns related to species management can support environmental policies on biological invasions in cities. Tailoring and implementing adequate management actions can benefit from incorporating cognitive but also affective factors of the public.

BIM for CREM: exploring the benefit of building information modelling for facility management in corporate real estate management
(2022) Benn, Maximilian; Stoy, Christian
The implementation of BIM in FM has been of steadily growing interest for academic research. Yet the benefits of BIM for the FM in CREM have, to the present day, been explored to a limited extent. As research on BIM for FM in CREM remains narrowly investigated, this study follows an exploratory approach to formulate implications for further research directions. Therefore, a four-stage procedure was adopted: (1) identification and definition of BIM uses for FM in CREM; (2) validation of the BIM uses for FM in CREM and the expert survey questionnaire; (3) assessment of each BIM use’s benefit by experts; and (4) analysis of the correlations between BIM uses’ benefit assessments and the respondents’ industries, the resulting associations, and the prioritisation for the development of BIM uses for FM in CREM. Based on that methodology, it was shown that the BIM use for FM in CREM with the highest priority for development is 46 Facilities and Equipment: Repair and Renewal. The BIM use with the lowest priority is 21 Visualisation. As a result, four implications on the development of BIM uses for FM in CREM were formulated regarding case studies, information requirements, and technical requirements, as well as process and personnel requirements.

Bio-modules : mycelium-based composites forming a modular interlocking system through a computational design towards sustainable architecture
(2023) Abdelhady, Omar; Spyridonos, Evgenia; Dahy, Hanaa
In a resource-constrained world, raising awareness about the development of eco-friendly alternative materials is critical for ensuring a more sustainable future. Mycelium-based composites (MBC) and their diverse applications are gaining popularity as regenerative, biodegradable, and lightweight alternatives. This research aims to broaden the design potentials of MBC in order to construct advanced systems towards a novel material culture in architecture. The proposed design method intends to explore the design and fabrication of small-scale components of MBC to be applied in modular systems. Mycelium-based modular components are being developed to fulfill the geometrical requirements that allow for the creation of a lightweight system without additional reinforcement. The modules are linked together using an interlocking system. Through computational design and form-finding methods, various arrangements of the modules are achieved. An initial prototype of five modules is created to demonstrate the ability of the system to form various geometrical configurations as a result of the used workflow. The proposed application aims to expand the scope of the use of mycelium-based composites in modular systems and to promote architectural applications using bio-based composite materials.

Biomimicry as a sustainable design methodology : introducing the ‘Biomimicry for Sustainability’ framework
(2022) Ilieva, Lazaara; Ursano, Isabella; Traista, Lamiita; Hoffmann, Birgitte; Dahy, Hanaa
Biomimicry is an interdisciplinary approach to study and transfer principles or mechanisms from nature to solve design challenges, frequently differentiated from other design disciplines by its particular focus on and promise of sustainability. However, in the biomimicry and biologically inspired design literature, there are varying interpretations of how and whether biomimetic designs lead to sustainable outcomes and how sustainability, nature, and mimesis are conceptualised and engaged in practice. This paper takes a particular focus on the built environment and presents a theoretical overview of biomimicry literature spanning across specific fields, namely architecture, philosophy, sustainability and design. We develop upon conceptual considerations in an effort to contribute to the growing calls in the literature for more reflective discussions about the nuanced relationship between biomimicry and sustainability. We further develop a ‘Biomimicry for Sustainability’ framework that synthesises recent reflective deliberations, as a possible direction for further theorisation of biomimicry, aiming to elaborate on the role of biomimicry as a sustainable design methodology and its potential to cultivate more sustainable human–nature relations. The framework is used as a tool for retrospective analysis, based on literature of completed designs, and as a catalyst for biomimetic design thinking. The objective of this paper is to serve as a point of departure for more active and deeper discussions regarding future biomimetic practice in the context of sustainability and transformational change, particularly within the built environment.

City and industry: how to cross borders? Learning from innovative company site transformations
(2021) Hüttenhain, Britta; Kübler, Anna Ilonka
While working and living coexisted in the historical city, the functions are separated in the Modernist city. Recently, the idea of connected urban districts with short distances and attractive work spaces have received renewed attention from companies and planners alike, as soft site factors, tacit knowledge, and local production are gaining importance. In this article we focus on the development of multi-national company sites and the economic and spatial conditions that encourage them to transform existing sites, improve placemaking, and cross borders. We also have a look at their interactive influence on the neighbourhood. We talked to the real estate managers of BASF, BMW, Bosch, Siemens, and Trumpf about site development strategies and approaches for connecting and mixing functions, and therefore crossing borders and, where it is necessary, separating. The professional discourse on “productive cities” and “urban manufacturing” is concerned with reintegrating production into the city. Reurbanisation is especially instrumental in overcoming a major guiding principle or dogma of the Modernist city: the separation of functions. Nevertheless, reurbanisation results in price rises and increases the competition for land. Therefore, planning has to pay attention to industrial areas, as well as housing or the inner-city. An important thesis of the article is that multi-national companies are pioneers in transforming their priority sites to suit future development. For cities, it is an upcoming communal task to ensure that all existing industrial areas develop into “just, green and productive cities,” as pointed out in the New Leipzig Charter. To a certain extent, it is possible to adapt the urban planning and design strategies of multi-national companies for existing industrial areas. This is especially true regarding the question of how borders and transition zones between industrial areas of companies and the surrounding neighbourhood can be designed to be spatially and functionally sustainable or how they can be transformed to suit future urban needs. However, urban planning has to balance many concerns and therefore the article concludes with a synopsis of the importance of strategic planning for transforming existing industrial areas.

Co-design methods for non-standard multi-storey timber buildings
(2023) Orozco, Luis; Krtschil, Anna; Wagner, Hans Jakob; Bechert, Simon; Amtsberg, Felix; Knippers, Jan; Menges, Achim
To meet climate change goals and respond to increased global urbanisation, the building industry needs to improve both its building technology and its design methods. Constrained urban environments and building stock extensions are challenges for standard timber construction. Co-design promises to better integrate disciplines and processes, promising smaller feedback loops for design iteration and building verification. This article describes the integrated design, fabrication, and construction processes of a timber building prototype as a case study for the application of co-design methods. Emphasis is placed on the development of design and engineering methods, fabrication and construction processes, and materials and building systems. The development of the building prototype builds on previous research in robotic fabrication (including prefabrication, task distribution, and augmented reality integration), agent-based modelling (ABM) for the design and optimisation of structural components, and the systematisation of timber buildings and their components. The results presented in this article include a functional example of co-design from which best practises may be extrapolated as part of an inductive approach to design research. The prototype, with its co-designed process and resultant flat ceilings, integrated services, wide spans, and design adaptability for irregular column locations, has the potential to expand the design potential of multi-storey timber buildings.

Computational optimisation of urban design models : a systematic literature review
(2024) Tay, JingZhi; Ortner, Frederick Peter; Wortmann, Thomas; Aydin, Elif Esra
The densification of urban spaces globally has contributed to a need for design tools supporting the planning of more sustainable, efficient, and liveable cities. Urban Design Optimisation (UDO) responds to this challenge by providing a means to explore many design solutions for a district, evaluate multiple objectives, and make informed selections from many Pareto-efficient solutions. UDO distinguishes itself from other forms of design optimisation by addressing the challenges of incorporating a wide range of planning goals, managing the complex interactions among various urban datasets, and considering the social-technical aspects of urban planning involving multiple stakeholders. Previous reviews focusing on specific topics within UDO do not sufficiently address these challenges. This PRISMA systematic literature review provides an overview of research on topics related to UDO from 2012 to 2022, with articles analysed across seven descriptive categories. This paper presents a discussion on the state-of-the-art and identified gaps present in each of the seven categories. Finally, this paper argues that additional research to improve the socio-technical understanding and usability of UDO would require: (i) methods of optimisation across multiple models, (ii) interfaces that address a multiplicity of stakeholders, (iii) exploration of frameworks for scenario building and backcasting, and (iv) advancing AI applications for UDO, including generalizable surrogates and user preference learning.

Cross-sectional 4D-printing : upscaling self-shaping structures with differentiated material properties inspired by the large-flowered butterwort (Pinguicula grandiflora)
(2023) Sahin, Ekin Sila; Cheng, Tiffany; Wood, Dylan; Tahouni, Yasaman; Poppinga, Simon; Thielen, Marc; Speck, Thomas; Menges, Achim
Extrusion-based 4D-printing, which is an emerging field within additive manufacturing, has enabled the technical transfer of bioinspired self-shaping mechanisms by emulating the functional morphology of motile plant structures (e.g., leaves, petals, capsules). However, restricted by the layer-by-layer extrusion process, much of the resulting works are simplified abstractions of the pinecone scale’s bilayer structure. This paper presents a new method of 4D-printing by rotating the printed axis of the bilayers, which enables the design and fabrication of self-shaping monomaterial systems in cross sections. This research introduces a computational workflow for programming, simulating, and 4D-printing differentiated cross sections with multilayered mechanical properties. Taking inspiration from the large-flowered butterwort (Pinguicula grandiflora), which shows the formation of depressions on its trap leaves upon contact with prey, we investigate the depression formation of bioinspired 4D-printed test structures by varying each depth layer. Cross-sectional 4D-printing expands the design space of bioinspired bilayer mechanisms beyond the XY plane, allows more control in tuning their self-shaping properties, and paves the way toward large-scale 4D-printed structures with high-resolution programmability.

Deformation behavior of elastomer-glass fiber-reinforced plastics in dependence of pneumatic actuation
(2021) Mühlich, Mona; González, Edith A.; Born, Larissa; Körner, Axel; Schwill, Lena; Gresser, Götz T.; Knippers, Jan
This paper aims to define the influencing design criteria for compliant folding mechanisms with pneumatically actuated hinges consisting of fiber-reinforced plastic (FRP). Through simulation and physical testing, the influence of stiffness, hinge width as well as variation of the stiffness, in the flaps without changing the stiffness in the hinge zone, was evaluated. Within a finite element model software, a workflow was developed for simulations, in order to infer mathematical models for the prediction of mechanical properties and the deformation behavior as a function of the aforementioned parameters. In conclusion, the bending angle increases with decreasing material stiffness and with increasing hinge width, while it is not affected by the flap stiffness itself. The defined workflow builds a basis for the development of a predictive model for the deformation behavior of FRPs.

Dog walkers’ views of urban biodiversity across five European cities
(2020) Fischer, Leonie K.; Kowarik, Ingo
Contact with nature makes people feel better, live healthier and act more environmentally-friendly. We hypothesized that dog walking, an omnipresent people–nature interaction in cities, translates to a more positive view of urban nature and, subsequently, to more support for conservation initiatives. Insights into such positive side-effects of dog walking are relevant for dog-related urban policies that often focus on negative impacts of dogs (e.g., health risks, disturbance of wildlife). Based on a field survey in five European cities (N = 3717), we analyzed if people who walked dogs regularly valued four urban ecosystem types (park meadows, wastelands, streetscapes, forests), and the plant species diversity within, differently from other people. Opposite to our hypothesis, participants from both groups valued urban ecosystems and their biodiversity very similarly across the cities. Thus, our study does not confirm that regular dog walkers value natural elements more than other people. It thus remains an important challenge for urban planners to balance services and disservices of dog walking in urban greenspaces.

Environmental impact of a mono-material timber building envelope with enhanced energy performance
(2022) Bucklin, Oliver; Di Bari, Roberta; Amtsberg, Felix; Menges, Achim
Broader adoption of timber construction is a strategy for reducing negative greenhouse gas (GHG) emissions created by the construction industry. This paper proposes a novel solid timber building envelope that uses computational design and digital fabrication to improve buildings’ energy performance. Timber beams are sawn with deep slits that improve thermal insulation and are milled with various joints for airtight, structural connections. To minimize embedded energy and to simplify disposal, the envelope is assembled without adhesives or metal fasteners. The building envelope is evaluated for thermal resistance and airtightness, and fabrication is evaluated for duration and power output during sawing. Finally, a Lifecycle Assessment (LCA) is carried out. The Global Warming Potential (GWP) is compared to that of other wood envelope systems with similar thermal conductance. Compared to other timber constructions with similar building physics properties, the proposed system showed lower GWP values (-15.63 kg CO2 eq./m² construction). The development and analysis demonstrate the potential to use digitally controlled subtractive manufacturing for improving the quality of solid timber to achieve higher environmental performance in building envelopes. However, further design and fabrication optimizations may be necessary to reduce required materials and production energy.

Extension of computational co-design methods for modular, prefabricated composite building components using bio-based material systems
(2023) Zechmeister, Christoph; Gil Pérez, Marta; Dambrosio, Niccolo; Knippers, Jan; Menges, Achim
Robotic coreless filament winding using alternative material systems based on natural fibers and bio-based resin systems offers possible solutions to the productivity and sustainability challenges of the building and construction sector. Their application in modular, prefabricated structures allows for material-efficient and fast production under tightly controlled conditions leading to high-quality building parts with minimal production waste. Plant fibers made of flax or hemp have high stiffness and strength values and their production consumes less non-renewable energy than glass or carbon fibers. However, the introduction of natural material systems increases uncertainties in structural performance and fabrication parameters. The development process of coreless wound composite parts must thus be approached from the bottom up, treating the material system as an integral part of design and evaluation. Existing design and fabrication methods, as well as equipment, are adjusted to emphasize material aspects throughout the development, increasing the importance of material characterization and scalability evaluation. The reciprocity of material characterization and the fabrication process is highlighted and contributes to a non-linear, cyclical workflow. The implementation of extensions and adaptations are showcased in the development of the livMatS pavilion, a first attempt at coreless filament winding using natural material systems in architecture.

Factors affecting the social acceptance of agricultural and solar energy systems : the case of new cities in Egypt
(2024) Marzouk, Mai A.; Fischer, Leonie K.; Salheen, Mohamed A.
Can the building sector become productive and, in parallel, help create livable spaces? Agricultural and solar energy systems can contribute to the building sector’s transformation; however, research on these systems has mostly focused on technological development and achieved gains, while overlooking a key driver of success, which is social acceptance. Only recently has the discussion on social acceptance of the systems gained momentum revealing that their adoption, especially in residential sectors, is bound to end users. Therefore, using a quantitative, survey-based, case study approach, we investigated what influences the social acceptance of end users, i.e., the residents of residential buildings in Egyptian new cities. Based on UTAUT - a Technology Acceptance theory - seven underlying factors were tackled using a statistical contingency analysis (SPSS, n = 274) to test their association with (a) social acceptance of agricultural and solar energy systems and (b) the sociocultural background of the residents. Results revealed that social acceptance of the systems was associated with factors like the expected effort for implementation, concerns and anxieties about the systems, external supporting conditions, and social influences – while surprisingly, it was not associated with the expected performance of the systems, their perceived costs, and the need for financial support. Most studied factors showed associations with the sociocultural aspects, except for the expected effort and perceived cost of solar systems and financial facilitations of both systems, which proved to be completely independent of the sociocultural background of the residents. The conducted analysis and concluded insights about the underlying factors behind social acceptance have not been previously covered in detail for the two systems in comparison, especially for the case of new Egyptian residences. The study findings can support relevant stakeholders such as policymakers, suppliers, engineers, etc. in triggering the social acceptance of the systems in Egypt and contexts of similar settings.
