From Cognitive Buildings to Digital Twin: The Frontier of Digitalization for the Management of the Built Environment
Full text linkThe BIM holistic approach leads the AEC sector to manage all the different disciplines involved in the construction process. Its nDimensions, indeed, concern geometry, structure, systems (3D), work-site management—also in terms of time and costs—(4D, 5D), safety, energy performances (6D), maintenance and building management (7D). Besides the analysis of the state of the art, the n + 1 dome case study has been used to explain the advantages of BIM, sensitization and digital tool application for both product and asset management (PIM, AIM). Finally, the chapter illustrates the potential of Internet of Things (IoT), Machine Learning (ML) and Artificial Intelligence (AI), moving from Cognitive to Predictive buildings, nowadays conceived as the new perspective of 4.0 construction
Timber-Based Transformations of the Built Environment: A Portfolio of Case Studies
No full textThe case studies collection is based on a literature review on architectural databases and a survey among the enterprises network. Twenty are the individual tabs among + 100 projects, these are selected mainly in the Italian context because of the high-density building stock composition perfectly fittable for this purpose. Finally, European projects choice starts from the Active House catalogue to point out these transformations sustainable approach. Case studies are catalogued according to the BAEIOU taxonomy described in chapter 1 : building Above, bEside, Inside, Outside, Under. Tabs show buildings before and after the intervention, their architectural concept, relation with the existing volume relationship and the timber-based system used for the extension, according to chapter 2 taxonomy
Existing Building Transformation: Current Drivers, Issues, and Possibilities
No full textConstructions account for a huge amount of energy and resources consumptions, affecting our indoor and outdoor living environment with pollutant emissions, for our planet and ourselves. Besides the climate change, the constant development of urban areas leads to an increasing demand for building spaces (most of all, with residential functions), and, therefore, to the urban densification phenomenon. All those different needs require to be addressed by a set of integrated and valuable design strategies for the sustainable transformation—versus demolition—of the built environment, by combining the energy retrofit of existing buildings and the definition of newer and healthier constructions, with the choice of the most proper technologies and materials to interact with existing structures and envelopes. The chapter introduces the concept of additive building transformation and proposes a different taxonomic approach to the construction layering, foreseeing a new possible paradigm of action towards a sustainable “palinsesto”
A Validation Opportunity: Case-Studies Analysis and Outcomes on the Application of the Method on Real Buildings
No full textBy closing the current dissertation, this chapter presents the practical implications of taleah methodology and tools, through the opportunity of testing them on two concrete case studies: 1 + 1 house and n + 1 dome. The first one represents the vertically-up densification phenomenon, small-scaled on the widely spread one-family houses; the second one identifies the same phenomenon at an urban scale; two diversified applications of the Building Above strategy, realized through timber-based construction systems. As per Galileo Galilei’s words, sensata esperienza, necessaria dimostrazione represents the spirit and structure of the research method, and the importance to resort to the demonstration of deducted hypothesis, as based on the observation of real phenomena. Working with real buildings is fundamental, indeed, in order to understand the reliability of the set procedures, as tested on different scenarios
A New Taxonomic Perspective on Wood-Based Technologies for the Transformation of the AEC Sector
Full text linkThe transformation of the built environment requests specific considerations in the definition of construction strategies. Under the technological perspective, the major requirements are lightness and efficiency, intended as the minimization of the impact over the existing building, along with the maximization of the building performances and overall value. To find suitable solutions, this chapter investigates wood as a construction material. At first, it defines the domain of the timber construction industry, by addressing the state of the art on wood innovations, between processes and products, according to the literature review and the outcomes from the interviews with international stakeholders. Afterward, it describes the taxonomic approach as a method to characterize building systems, proposing a revision of the current classification approach and the introduction of a creative taxonomy of timber-based construction systems. Finally, this taxonomy review is used to structure the final case-history survey upon timber construction strategies for building transformation, whose methodology and results are presented accordingly
An Innovative Method for the Management of the Building Process
No full textThrough always more innovative IT applications, the construction industry is moving towards the digitalization of the building process, from digital design to automated manufacturing and smart buildings. Big data are now able to take us into an augmented reality—the virtual sibling of the real one—where buildings become cognitive and predictive, capable to actively interact with people. Towards this direction, the capability to store and organize building information at any level of its lifecycle is essential, especially when the multi-criteria evaluation of buildings’ behavior is required. Within this framework, the chapter introduces the review of the standards and best practices, mainly focusing on BIM as the driven method for the management of the entire building process. Hence, the methodology to develop a new assessment tool is presented, according to the investigation of the current platforms for the evaluation of buildings’ performances, and the pursued methods to define new additional shared parameters, specifically customized for the application to retrofit design solutions with timber-based construction systems
A BIM-enabled Decision Support System to support large-scale energy retrofitting processes and off-site solutions for envelope insulation
Full text linkThe urgency of renewing the Architecture, Engineering and Construction related processes to increase quality standards and performances while reducing costs and operations time is widely discussed in literature. In this scenario, increasing the energy renovation rate of the existing European building stock is a key priority to support the EU's 2050 decarbonisation targets through innovative solutions. The introduction of prefabricated panels for building renovation – incorporating insulation, mechanical systems, and finishing – can provide the existing buildings with improved structural, thermal, acoustic, and architectural features. The higher quality and safety for the off-site activities, the faster on-site application and the reduction of waste are some advantages of this typology of Modern Methods of Construction (MMC). Several digital and informative tools have been introduced over the last years to customize and integrate the design of prefabricated panels on existing building envelopes (i.e. panelisation tools). However, the comparison of technological alternatives is left to the intuition of designers and managed through the use of several tools that are not interconnected and often downstream the design process. This paper presents a Panelisation Design Tool, which is a Decision Support System (DSS) to help decision-makers in the choice of technological solutions for retrofitting operations during the Early Design Stage. Thanks to BIM integration, some indicators related to different aspects (n Dimensions) are extracted from the model of the panelised building to compare different technologies in a systematic way. The Panelisation Design Tool is tested on a case study building located in the city of Monza, in Northern Italy, used as a pilot in the BIM4EEB European Project. The test aimed at demonstrating the effectiveness of the chosen parameters to evaluate multiple technological solutions in an integrated BIM approach
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
