    Process digitalisation and automation is unstoppable in all industries, including construction. However, its widespread adoption, even for non-experts, demands easy-to-use tools that reduce technical requirements. BIM to BEM (Building Energy Models) workflows are a clear example, where ad-hoc prepared models are needed. This paper describes a methodology, based on graph techniques, to automate it by highly reducing the input BIM requirements found in similar approaches, being applicable to almost any IFC. This is especially relevant in retrofitting, where reality capture tools (e.g., 3D laser scanning, object recognition in drawings) are prone to create geometry clashes and other inconsistencies, posing higher challenges for automation. Another innovation presented is its multi-scale nature, efficiently addressing the surroundings impact in the energy model. The application to selected test cases has been successful and further tests are ongoing, considering a higher variety of BIM models in relation to tools and techniques used and model sizes.The authors would like to express the gratitude to the European Commission by funding the research projects BIM4REN, EPCRECAST and ENSNARE (Grant Agreement No. 820773, 893118 and 958445, respectively), under the Horizon 2020 programme, where the presented work was conducted.

    The European building industry is facing a strong increase in renovation processes, which are still non-cost-effective, involve unproperly coordinated stakeholders, are disturbing for the occupants, and cause important inefficiencies in the overall renovation process. In this context, digitalization and Building Information Modelling (BIM), as an enabler, is the key solution that may drive renovation interventions to ensure a more successful and leaner process, aiding the whole value chain of actors to achieve its full potential. This research describes the OpenBIM methodology applied in order to transform the implicit knowledge from the stakeholders involved in the building renovation process, not structured enough for automation, into an OpenBIM digital process based on the BIM standards. The outcomes of this research are the OpenBIM ready workflows that represent the renovation process and information requirements according to the involvement of different stakeholders rooted in the analysis of barriers, requirements, and needs. Those workflows are the basis for the future development of specific products and tools for boosting digitalization and interoperability in the renovation process.This work has been developed within the project BIM4Ren.

    Although construction is one of the largest industries in the world, it is one of the least digitised and its productivity is still very low. Excesses of time and cost are common and are even more accentuated for building renovation. Recently, the building information modeling (BIM) methodology has strongly entered in the construction sector and appears to be an effective paradigm shift. Considering all of the previously mentioned aspects, this article addresses the identification and analysis of the critical barriers of renovation and the potential for digitalisation to overcome them using BIM. The methodology that was used is based on an open innovation approach called Living Labs, where consultations with the key stakeholders of the construction process aims for a higher digitalisation to focus on real needs and fitted to the user’s requirements. Starting from a worldwide survey, the analysis of the Spanish casuistry is deepened. From the analysis of barriers and opportunities, the necessary requirements for an optimal BIM application in renovation are highlighted. After identifying the key aspects that each stakeholder’ typology has considered as relevant, a set of key performance indicators have been selected, to monitor the improvements in the renovation process when BIM is adopted.This work has been developed within the project BIM4Ren.

    "Prävention ist keine 'Eintagsfliege'": Herausforderungen und Bedarfe der Prävention islamistischer Radikalisierung aus lokaler Perspektive in Nordrhein-Westfalen

    Get PDF
    Prävention gegen islamistische Radikalisierung ist nach wie vor ein wichtiges Politikfeld in Nordrhein-Westfalen. Wie aber stellt sich die aktuelle Problemlage aus Sicht kommunaler Präventionsakteure im Bundesland dar? Wo sehen lokale Präventionsberaterinnen und -berater, Lehrkräfte, Fachkräfte der Sozialen Arbeit, kommunale Behördenvertreterinnen und -vertreter sowie Polizistinnen und Polizisten die aktuell größten Herausforderungen? Welchen Beitrag können sie in ihrem Arbeitsfeld zur Verhinderung einer islamistischen Radikalisierung leisten? Was für Bedarfe haben sie in dieser Hinsicht? Was braucht es für eine wirksame Prävention? Und was wird unter dem Begriff der "Prävention" überhaupt verstanden? Diese Fragen stehen im Zentrum dieses BICC Working Paper. Wir unterscheiden dabei zwischen einem engen und einem breiten Verständnis von Prävention. Präventionsarbeit im engeren Sinn bezieht sich auf die konkrete Fallarbeit mit Individuen, die bereits Anzeichen einer Hinwendung zu islamistischen Ideologien und/oder Szenestrukturen erkennen lassen, sowie auf Aufklärungs- und Sensibilisierungsmaßnahmen. Breiter gefasste Prävention setzt hingegen bei den angenommenen strukturellen Ursachen islamistischer Radikalisierung an. Die Herausforderungen in diesem Arbeitsfeld spiegeln häufig größere gesellschaftliche Kontroversen, beispielsweise rund um das Thema "Integration", wider. Breit gefasste Prävention befasst sich zudem meist mit verschiedenen Ausformungen des Extremismus, etwa auch mit antimuslimischem Rassismus und Rechtsextremismus

    CRISPR/Cas9-mediated glycolate oxidase disruption is an efficacious and safe treatment for primary hyperoxaluria type I

    CRISPR/Cas9 technology offers novel approaches for the development of new therapies for many unmet clinical needs, including a significant number of inherited monogenic diseases. However, in vivo correction of disease-causing genes is still inefficient, especially for those diseases without selective advantage for corrected cells. We reasoned that substrate reduction therapies (SRT) targeting non-essential enzymes could provide an attractive alternative. Here we evaluate the therapeutic efficacy of an in vivo CRISPR/Cas9-mediated SRT to treat primary hyperoxaluria type I (PH1), a rare inborn dysfunction in glyoxylate metabolism that results in excessive hepatic oxalate production causing end-stage renal disease. A single systemic administration of an AAV8-CRISPR/Cas9 vector targeting glycolate oxidase, prevents oxalate overproduction and kidney damage, with no signs of toxicity in Agxt1(-/-) mice. Our results reveal that CRISPR/Cas9-mediated SRT represents a promising therapeutic option for PH1 that can be potentially applied to other metabolic diseases caused by the accumulation of toxic metabolites

    The objective of this study is to evaluate the practical application of a digital process for the buildings’ energy rehabilitation using prefabricated modules. The literature is extensive in this aspect, numerous technologies are mentioned for the digitalization of buildings’ rehabilitation process (BIM, laser scanner, drones, etc.), and there are also many prefabricated products for rehabilitation, but its introduction in the market is still very limited. This is due in part to the uncertainty in its practical application, and the difficulties that may entail changing processes, digitizing them, and integrating innovations in a sector as conservative as construction. Within BERTIM project, prefabricated wooden modules that integrate both carpentry and HVAC distribution networks and a methodology for the energy rehabilitation of buildings through a digitalized process have been developed. These developments have been implemented in two buildings which has allowed to identify the main barriers and difficulties that construction companies encounter in the execution. The main difficulties are: i) the method of capturing building data for the generation of its BIM model, ii) the integration of the HVAC distribution networks into the modules iii) the installation procedure of the modules on the existing building façade so that minimum execution times are ensured even in façades with many deviations and a large lack of verticality. This study addresses these difficulties and proposes practical solutions that will allow industrials to implement digital processes and will foster the use of prefabricated modules in the buildings’ energy rehabilitation.The authors want to recognize BERTIM project on Energy rehabilitation of buildings with prefabricated timber modules as the main framework of the present study. The project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No 636984. The authors would also like to thank all the members of the consortium for their technical and scientific contributions
