Enabling the Development and Implementation of Digital Twins : Proceedings of the 20th International Conference on Construction Applications of Virtual Reality

Welcome to the 20th International Conference on Construction Applications of Virtual Reality (CONVR 2020). This year we are meeting on-line due to the current Coronavirus pandemic. The overarching theme for CONVR2020 is "Enabling the development and implementation of Digital Twins". CONVR is one of the world-leading conferences in the areas of virtual reality, augmented reality and building information modelling. Each year, more than 100 participants from all around the globe meet to discuss and exchange the latest developments and applications of virtual technologies in the architectural, engineering, construction and operation industry (AECO). The conference is also known for having a unique blend of participants from both academia and industry. This year, with all the difficulties of replicating a real face to face meetings, we are carefully planning the conference to ensure that all participants have a perfect experience. We have a group of leading keynote speakers from industry and academia who are covering up to date hot topics and are enthusiastic and keen to share their knowledge with you. CONVR participants are very loyal to the conference and have attended most of the editions over the last eighteen editions. This year we are welcoming numerous first timers and we aim to help them make the most of the conference by introducing them to other participants

Designing supplementary space in multi-family housing

La démographie et les modes de vie ont considérablement évolué au cours des dernières décades. De tels changements sont destinés à influencer la conception de l’habitation et ils incluent notamment une série de besoins émergents: s’en suivent des besoins additionnels en espace pour répondre à l’arrivée de ces activités additionnelles au niveau du logement. La planification en vue de répondre à ces besoins émergeants constitue le principal thème de la présente thèse. Dans le cas de la maison unifamiliale détachée, le sous-sol est disponible pour offrir des espaces appropriés à ces besoins émergents. Par contre, une telle ressource n’est normalement pas présente dans le cas d’un édifice multifamilial. La thèse propose un espace additionnel spécifique en vue de répondre à ces besoins émergents : l’espace supplétif. Même si un tel espace n’est pas envisagé dans les publications du domaine, des précédents existent quant à sa présence en planification multifamiliale. Le but de la présente étude est d’offrir des lignes directrices quant à la conception et l’intégration d’un tel espace supplétif. Elle va s’appuyer sur l’approche systémique en raison de la logique de déduire la solution à partir d’une analyse de l’objectif. L’application de l’approche systémique implique donc que tous les critères correspondant à la nature spécifique de l’espace supplétif seront extrapolés à partir de l’objectif. Dans le cas la présente étude, ce sont les critères du bureau à domicile qui seront d’abord précisés car il s’agit de l’activité émergente la plus exigeante. Les critères seront traités comme vecteurs d’un modèle générique indicatif de la manière d’organiser l’espace supplétif. Ce modèle visera le bureau à domicile en vue d’offrir les solutions pertinentes et il se concentrera principalement sur les critères d’intimité visuelle et spatiale. La contribution du modèle sera de suggérer des lignes directrices en vue d’incorporer l’espace supplétif à l’intérieur des édifices résidentiels de type multifamilial, ce que la planification conventionnelle n’offre pas. C’est le concept d’adaptabilité qui est à la base de toute stratégie visant à permettre le changement en architecture et en habitation, d’autant plus lorsqu’il s’agit d’un espace supplétif. À cet effet, l’espace supplétif va recourir à l’approche Open Building afin d’appliquer le concept d’adaptabilité, en raison de ses avantages majeurs tant au niveau conceptuel que constructif. Différentes applications de l’approche Open Building, telles que le projet NEXT21 et le protocole KSI (Kikou support and Infill), offrent des exemples susceptibles de constituer d’efficaces lignes directrices pour la conception d’un espace supplétif. La faisabilité du modèle d’espace supplétif proposé est vérifiable et démontrable dans le monde réel. Les systèmes constructifs industrialisés sont en mesure de permettre le changement sans démolition car leurs joints mécaniques « à sec » rencontrent généralement les normes DfD (Design for Disassembly), non seulement en ce qui concerne l’espace supplétif mais pour l’ensemble du logement.Demographics and lifestyles have changed considerably in the past few decades. These changes are bound to influence the design of housing and they notably include a series of emerging needs: additional spatial needs due to additional activities brought to the traditional housing premises. Planning for those emerging needs is the main theme of this thesis. In a typical single-family detached house, the basement is available to accommodate the spatial requirements for these emerging needs. However, such a provision does not typically exist in multi-family housing. This thesis proposes a specific additional space to accommodate these emerging needs: the supplementary space. Although such a space has not been explored in the literature, there are precedents for its application in multi-family floor planning. The objective of this study is to provide guidelines for the design and the integration of this supplementary space. It relies on the systems approach as the design-decision methodology due to its logic of deducting the solution from the analysis of the objective. Applying the systems approach means that all the criteria corresponding to the specific purpose of the supplementary space will be extrapolated from the objective. However, once the supplementary space is being used to deal with emerging needs, it will then introduce its own relevant criteria. This study will start with the criteria for designing a home office because this is the most demanding emerging needs activity. The criteria are organized as vectors of a generic model indicating how the supplementary space can be formulated. The model will target the workplace at home and subsequently offer solutions to them. This study focuses on the planning provisions dealing mainly with visual and spatial privacy. The overall outcome of the model is to suggest guidelines to incorporate the supplementary space within multi-family residential buildings, a feature not offered in traditional planning. The concept of adaptability is the key design strategy to accommodate change in architecture and housing, even more in the case of a supplementary space. Therefore, the supplementary space model will apply the concept of adaptability through the Open Building (OB) approach; elaborating more on the practical design and construction features. Different OB applications, such as the NEXT21 project and the KSI (Kikou Support and Infill) protocol in Japan, are examples that can be used as efficient guidelines to design a supplementary space. The feasibility of the supplementary space model can be validated and served in the real world. Industrialized building systems are capable of accommodating change without demolition as their dry mechanical joints are generally at meeting the DfD (design for disassembly) standards, not only for the supplementary space but also for the whole dwelling unit

CHANCES. Practices, Spaces and Buildings in Cities' Tranformation

CHANCES has been an international conference that was aimed to explore, from a multidisciplinary perspective, the fragile but continuous urban transformation through the effective contribution of culture, nature and technology. The aim of this conference was to provide a deeper understanding of urban transformations’ research and practices, focusing on the use, re-use, design, renovation and innovative governance and management of public spaces, urban commons and buildings. We believe that these thoughts will largely contribute to shape and increase sustainable design, construction and planning in constant cities’ transformation. Contributions could build on reflections and studies concerning current or historical approaches that are changing or drastically changed the cities we lived in

“But eyes are blind. You have to look with the heart”. IBA Berlin 1979 – 1987, the drawing as tool to read and disclose

"It is only with the heart that one can see rightly; what is essential is invisible to the eye.” (Costanzo, 1991, p.14) On the occasion of his direction of the Berlin International Bauausstellung (IBA 1979-1987) the German architect Josef Paul Kleihues referred to the fable of Antoine de Saint - Exupéry to encourage architects to awaken the values of ingenuity and imagination. He emphasized the Imago, as a point of reference and stable values at the base of human consciousness. The problem is based on the dialectic between tradition and modernity, the field of experimentation on which he himself elaborates the concept of "critical reconstruction". According to the architect, the rediscovery of the laws of the historic city is a decisive instrument for Berliners to recognize themselves in it. Another important concept which Kleihues placed at the base of his guidelines is the "poetic rationalism" presented during the Triennale di Milano exhibition entitled "The cities of the world of 1988 and the future of the metropolis". On this occasion, he maintained that "the possibility of a new rationalism exists only when the deterministic tendency is questioned by poetry". (Kleihues, 1989, p.57) Through this “poetic rationalism”, he criticizes the excessive bureaucracy that conditions and limits the creative process. One of the most interesting areas of the Berlin International Bauausstellung is the Südliche Friedrichstad. It is interesting to take into account the rules imposed by Josef Paul Kleihues about the permanence of the existing layout and the reconstruction of the continuity of the facades along the plot perimeter and to see how the architects Aldo Rossi and Rem Koolhaas stand about these principles. The proposed study investigates their interpretation of the concept of "poetic rationalism" through drawing, considered by the author as a fundamental interpretative, creative and cognitive activity

Changing Priorities. 3rd VIBRArch

In order to warrant a good present and future for people around the planet and to safe the care of the planet itself, research in architecture has to release all its potential. Therefore, the aims of the 3rd Valencia International Biennial of Research in Architecture are: - To focus on the most relevant needs of humanity and the planet and what architectural research can do for solving them. - To assess the evolution of architectural research in traditionally matters of interest and the current state of these popular and widespread topics. - To deepen in the current state and findings of architectural research on subjects akin to post-capitalism and frequently related to equal opportunities and the universal right to personal development and happiness. - To showcase all kinds of research related to the new and holistic concept of sustainability and to climate emergency. - To place in the spotlight those ongoing works or available proposals developed by architectural researchers in order to combat the effects of the COVID-19 pandemic. - To underline the capacity of architectural research to develop resiliency and abilities to adapt itself to changing priorities. - To highlight architecture's multidisciplinarity as a melting pot of multiple approaches, points of view and expertise. - To open new perspectives for architectural research by promoting the development of multidisciplinary and inter-university networks and research groups. For all that, the 3rd Valencia International Biennial of Research in Architecture is open not only to architects, but also for any academic, practitioner, professional or student with a determination to develop research in architecture or neighboring fields.Cabrera Fausto, I.

Hybrid Heritage: An Investigation into the Viability of 3D-Printed Mashrabiya Window Screens for Bahraini Dwellings

Current debates on design and manufacturing support the claim that the ‘Third Industrial Revolution’ has already started due to Additive Manufacturing (AM) and 3D Printing. The process of solidifying liquid or powder using a binding agent or a melting laser can save time and transportation costs associated with importing primary material if locally sourced material is available. This research investigates a framework approach, titled SAFE, for discussing the functionality, economic viability, production feasibility, and aesthetic and cultural value lent by 3D printing on an architectural scale through a construction known as a Mashrabiya. This traditional window screen has distinguished aesthetic, cultural yet functional constraints, and there is a manufacturing gap in the market that makes it a viable product option to be 3D printed. The practical element and design process related to reviving this screen are examined, from complex geometry development to cost and fabrication estimations. 3D printing technologies potentially offer solutions to solve issues in construction and assembly times, reduce labour costs, and address the loss of hand craft making skills in a variety of cultures, typically Middle Eastern ones; this was a factor in the abandonment of old Mashrabiya in houses typified with Bahrain as a case. Presently, there is a growing wealth of literature that highlights not only the strength of Mashrabiya as a design concept but also as a possible 3D printed product. Interviews with a total of 42 local Bahraini manufacturers, academics and architects as well as 4 case studies and 2 surveys and 11 focus groups are hybrid mixed methods used to define a new 3D printed Mashrabiya (3DPM) prototype. The future of the 3D Mashrabiya prototype is further supported by economic forecasts, market research, and interviews with global manufacturers and 3D printing designers’ insights into the subject in an accretive design process. The research contributes to an understanding of the implications of technologies that enable mass customisation in the field of 3D-printed architecture in general and in the Bahraini market in particular. The process for developing a prototype screen and in determining its current economic value will prove significant in predicting the future benefits and obstacles of 3D-printed large scale architectural products in the coming five years as advised by industry experts. The main outcomes relate to establishing boundaries determining the validity of using 3D printing and a SAFE framework to produce a parametric Mashrabiya and other similar heritage architectural archetypes. This can be used to enhance the globalism of the design of Middle Eastern dwellings and to revive social identity and cultural traditions through innovative and reasonable yet superior design solutions using a hybrid architectural design language

A Finance Model for the Built Cultural Heritage - Proposals for improvements of future Heritage Economics

Abstract The new role of built cultural heritage, as an economic asset for development strategies and the widened definition of built heritage as a concept-, explains today’s affluence of sites. These can only be guaranteed with sufficient heritage funding. Financers’ inducement to fund cultural heritage depends on that heritage’s current value estimation and only highly revered sites qualify for support. Case studies imply that values are incessantly present in heritage and so these can be re-established when the right external conditions, or actions, arise. The assessment i.e. reflects the human perception of values projected onto buildings and not the physical characteristics of the heritage itself. This is way it is possible to modify finance incentive conditions. Finance models are needed but prototypes of such finance models are lacking. This inquiry aspires to supplement the findings of Cultural Economics, but from the viewpoint of actual building conservation practice. The aim of this doctoral thesis is to investigate the prospects of securing the successful future of built heritage by proposing a value stabilizing finance model, based on; the acquiring, the economizing and the assuring of heritage funding. The strategy of this inquiry involves five steps. Accelerators proved to determine all aspects of the heritage finance model, since these accelerators stabilize the values of built heritage sites by revealing the payback capacity of financial commitments to that heritage. Heritage funding in Sweden has stagnated due to weak emotional and financial accelerators, which means built heritage is at risk of falling into decay. The suggested contribution of this inquiry is the exploratory analysis of the mechanisms behind heritage funding including its accelerators, hence introducing new terminology into building conservation instigated by the idiom of economics, which could ease future strategic planning of heritage funding
